                             EXECUTIVE SUMMARY
                            Vision for EPA's Geospatial Program
   EPA will improve protection of the environment and public health through the efficient and
             effective use of geospatial data and technologies to conduct business
Background and Context

Regulators, analysts, researchers, and policy-makers have come to recognize that place is valuable for
understanding environmental interactions, health effects, and environmental performance. Data that
identify the geographical location and characteristics of natural or man-made features and boundaries, or
geospatial data, are invaluable for most planning and decision-making activities at EPA.  The EPA
Geospatial Activities Baseline Assessment, completed in June 2001, identified more than 500 people, in
nearly all EPA Program and Regional offices, who use geospatial data and technologies to support key
business operations. Many more benefit from the products developed.

While the  value of geospatial technologies to support business across the Agency has been demonstrated,
several issues have limited the Agency's ability to optimize investments already made. Investments in
these geospatial data and technologies are primarily made by individual offices, with relatively little
cross-Agency coordination.  Geospatial data and tools developed in one office are often difficult to find
and share with  another, even when needs are similar. There  is no recognized leadership to foster
coordination among offices using geospatial technologies. Many existing and potential EPA geospatial
data and technology users and managers interviewed during  the Baseline effort noted frustration with
finding and gaining access to data and tools, with the quality and availability of data, and with
telecommunications capacity. They indicated that these difficulties hindered their use of locational
analysis in their operations.  Recognition of the importance of these data  and technologies to EPA and
their extensive, but uncoordinated, use has led to development of this Geospatial Blueprint.

Proposed Geospatial Program

This Blueprint  proposes a Geospatial  Program that will leverage geospatial investments for EPA. The
Geospatial Program has been conceived and developed based on input and insights from individuals
across the  Agency. This Blueprint outlines five major goals  that support other key government-wide and
Agency-wide information management strategic planning efforts such as the EPA Strategic Information
Plan, the Federal and Agency Enterprise Architecture, and the Environmental Information Exchange
Network (Exchange Network). Implementing the strategic goals and actions of this Blueprint will result
in a Program that provides coordinated discovery, acquisition, management, and delivery of geospatial
data, as well as faster, easier, and less costly access to applications for manipulating geospatial data. The
Blueprint will enable the Agency to move from an environment where geospatial tools are considered
ancillary to addressing business activities to one where they  are viewed as essential to programmatic
operations.

The Geospatial Program will support  the geospatial component of the Federal and Agency Enterprise
Architecture and ensure its alignment with key activities such as Enterprise Repositories, the Central Data
Exchange, the System of Access, and the System of Registries.  Additionally, the Geospatial Program will
provide effective external representation of EPA's geospatial interests in  the government-wide National
Spatial Data Infrastructure and Geospatial One-Stop initiatives.

Geospatial Program Goals

The Geospatial Program goals were specifically developed and organized based on the components of the
Federal and Agency Enterprise Architecture. These goals are supported by objectives and actions which
are summarized below and described in detail in the remainder of this Blueprint.

GOAL 1:  BUSINESS PROCESSES: Improve EPA decision-making by incorporating location-
based approaches, data, tools and knowledge into EPA business processes.

       Objectives: EPA managers, Program staff, and information service providers understand the
       importance, costs, and value of location-based analyses and decision-making.
       •      Involve managers and staff in developing the Geospatial Blueprint and Program,
       •      Recognize the importance of and incorporate location into Agency strategic planning and
              Enterprise Architecture planning efforts,
       •      Foster an understanding of Agency business functions and assess location-based needs,
              and
       •      Conduct cost-benefit analyses of geospatial approaches.

GOAL 2: DATA ARCHITECTURE: Provide EPA, its partners, and the public with the geospatial

GOAL 4: TECHNOLOGY ARCHITECTURE: Design and implement an enterprise-wide
technical infrastructure that supports access, use, management, and delivery of distributed
geospatial data, applications, and Web services in a seamless manner.

       Objectives: EPA staff and EPA contractors have access to hardware and bandwidth in secure,
       interoperable networks that provide public access as appropriate.
               Identify, incorporate, and support high speed network requirements for geospatial data
               and tool sharing within the Enterprise Architecture,
               Ensure hardware and networks are in place for managing and accessing data as necessary
               to support Region and Program needs,
               Identify and set priorities for funding and other requirements to support distributed,
               networked, hardware and software installations,
               Promote EPA staff participation in various industry and government standards efforts to
               ensure Agency interoperability and openness, and
               Establish effective means for public access to EPA data and analyses.

GOAL 5: GOVERNANCE: Establish an effective governance structure for setting priorities for
geospatial investments, coordinating  geospatial efforts, and communicating how geospatial data
and technologies are used within the Agency.

       Objectives: EPA managers and staff clearly define roles and responsibilities for leadership and
       coordination in geospatial activities, including incorporation of a strategic planning process that
       assists in establishing priorities, appropriate policies for ensuring coordination, and partnership
       opportunities.
               Establish leadership mechanism(s) (e.g., Geospatial Information Officer or Geospatial
               Committee) for guiding geospatial efforts within the Agency,
               Clarify roles and responsibilities for geospatial data collection, management, analysis,
               distribution,
               Identify and set priorities for geospatial investments based on Agency needs,
       •       Establish process to identify, adopt and implement needed standards, and
               Encourage and support partnerships for data and tool development.

Implementation of these various actions will be monitored, and necessary changes in course identified
and taken. The Geospatial Program is intended to be a flexible and evolving effort that takes advantage
of new and innovative technologies to assist Agency business needs.

Next Steps and Timeline

Several actions outlined in this Blueprint have already been initiated. Staff and managers from all key
Program  offices and all Regions have been involved in the development of this document. Conversations
with key  information  technology staff responsible for the Enterprise Architecture and the Environmental
Information Exchange Network are ongoing.  An announcement for the GIO position has been issued and
will soon be filled.  The actions outlined above and described  in more detail in the following pages
represent the major next steps in developing a robust and effective Geospatial Program at EPA. Details
about the timing and sequencing over the next several years are described for the various activities.
Initial schematics and proposals for the  geospatial components of the overall Enterprise Architecture are
contained in the appendices of the document.  Within five years EPA will realize the full benefits of

developing a coordinated and integrated Geospatial Program. Please contact Wendy Blake-Coleman (202-
566-1709) for more information.

                                  INTRODUCTION
                           Vision for EPA's Geospatial Program
   EPA will improve protection of the environment and human health through the efficient and
             effective use of geospatial data and technologies to conduct business
Background and Context

The mission of the U.S. Environmental Protection Agency (EPA) is to protect human health and the
environment. Nearly every aspect of environmental management can be associated with a location on
earth. Incorporating data that identify the geographical location and characteristics of natural or man-
made features and boundaries, or geospatial data, into business operations can dramatically improve the
effectiveness of environmental planning and decision-making processes.

Currently, more than 500 people at EPA directly use geospatial data and technologies while many others
rely on the maps and analyses developed by them for planning and decision making. Millions of dollars
are expended annually at EPA for geospatial data, applications, and technologies, primarily on a project
or program-specific basis.  Yet, data and tools developed in one program are often difficult to share with
others, even when needs are similar, sometimes resulting in a duplication of efforts.

In 2001, the "Geospatial Activities Baseline Assessment" documenting the extensive use of geospatial
data and technologies across all EPA Programs  and Regions was completed. The Baseline summarizes a
number of issues that currently hinder Agency staff from using these data and technologies effectively.
This Blueprint builds on the Baseline Assessment by outlining a Geospatial Program that will serve the
interest of EPA as a whole. It outlines a cross-Agency Geospatial Program that coordinates and
establishes practices for geospatial data and technology, leverages resources, and contributes to better
information management and decision-making at EPA.

Several other information management initiatives are also underway at EPA. This Geospatial Blueprint is
evolving in conjunction with the Agency Enterprise Architecture, which will ultimately provide the
framework for all uses and investments in information technology at EPA. The Geospatial Program will
ensure that the Enterprise Architecture efforts appropriately consider and incorporate geospatial assets.
Work that is underway with the states and tribal governments to develop the Environmental Information
Exchange Network (Exchange Network) has been expanded to consider the locational aspects of
environmental data transported over the network.  For example, the FY 2003 Exchange Network Grant
solicitation makes activities that would improve locational coordinates for facilities, areas or boundaries
needed to carry out EPA, State, Tribal and/or local environmental programs eligible for funding.  Finally,
the Geospatial Program will provide a much-needed focal point for geospatial aspects of priority
activities at EPA, including environmental indicators, siruational analyses, and homeland security
responsibilities.

Outside of EPA, several  efforts are underway to coordinate geospatial activities, including the activities
of the Federal Geographic Data Committee to build the National Spatial Data Infrastructure and the
interagency Geospatial One-Stop initiative.  EPA's Geospatial Program will provide a mechanism for
coordinating Agency representation in these external activities and ensure the effective communication of
government-wide directives within EPA.

Use of Geospatial Technologies at EPA

Current Use

Environmental and public health protection requires not only an understanding of the distribution and
current conditions of environmental resources, but the ability to correlate pollutant behavior. This
includes where they are released, where they settle, where they may cause damage to both humans and
natural resources, where control and regulatory mechanisms must be applied, and where monitoring is
essential. These all require correlating locations against other variables and establishing relationships.
Facilitating these connections is a primary function of geospatial applications.  Examples of the EPA
activities that use geospatial applications include the following:

Program Offices
•      Protecting drinking water supplies
       Conducting analyses to help manage urban/suburban growth
•      Responding to oil spills and other emergency situations
       Identifying sources of pollution for source water protection
•      Examining and allocating regional  acid precipitation allowances
       Conducting risk assessments
•      Analyzing health conditions against pollutant distribution
       Modeling the distributions  of invasive species
•      Identifying priority sites for cleanup and enforcement actions

Regional Offices
       Developing Total Maximum Daily Load (TMDL) assessments for water bodies
•      Tracking toxic substances
       Cleaning up and monitoring Superfund sites
•      Monitoring water quality
•      Assessing children's health
•      Analyzing environmental justice situations
       Cleaning up hazardous waste sites
•      Conducting environmental  justice assessments
       Evaluating air emissions and ambient air concentrations
•      Modeling watersheds and storm water drainage systems

Office of Research and Development
       Conducting habitat assessments and risk analyses
•      Detecting and evaluating landscape patterns and changes
       Conducting real-time environmental monitoring and sharing the data with appropriate partners
       and stakeholders.
       Studying the effects of urbanization, at various scales
•      Developing accuracy assessment protocols
       Creating 3-D visualizations of specific sites or larger geographic areas
•      Analyzing the relationship  between health and environmental  contaminants

Issues with Use
While there are a wide variety of geospatial applications within EPA, most users believe that the Agency
is not fully optimizing and leveraging how these tools are used.  The Geospatial Activities Baseline
Assessment identified a number of concerns that currently affect the ability to leverage existing resources
at EPA.  These include:

•      Multiple sites of geospatial activity and no overall coordination or leadership, resulting in
       redundancy and an inability to leverage shared resources;
•      Inability to find, access, and use current and complete geospatial data sets to support needed EPA
       analyses;
•      Minimal existing quality control procedures to assist in developing and understanding the quality
       of geospatial data that EPA produces and accesses;
•      Lack of resources and flexibility to develop shared data resources with external partners (e.g,
       states and other federal agencies);
•      Inadequate bandwidth and telecommunication functionality to support transfers of large
       geospatial data sets;
•      Inability to share geospatial knowledge (including applications) easily across Programs and
       Regions; and
•      Lack of training for use of tools and development of skills at all levels (casual user to
       programmer).

Benefits of Implementing the Blueprint

The Geospatial Program outlined in this Blueprint will increase the effectiveness and efficiency of
geospatial technology use at EPA in a variety of ways. Examples of benefits possible with an effective
EPA Geospatial Program include:

•      Enhanced ability to develop and use indicators of environmental condition such as the extent of
       wetlands, emissions of pollutants, and ambient environmental conditions;
•      Improved ability to conduct multi-media environmental analyses;
       Improved response to situations involving hazardous materials;
•      Improved means to use locational information obtained during the course of regulatory reporting
       and permitting processes;
•      Better access to and use of distributed data sources and tools both inside and outside EPA through
       improved communication and web services; and
•      Improved ability to integrate real-time environmental data for environmental assessment,
       emergency response, and enforcement activities.

Organization of this Document

The remainder of this Geospatial Blueprint presents the components of the Geospatial Program.  These
are presented in the same framework as the Enterprise Architecture:

•      Understanding Agency business processes and how geospatial information can support them;
       Identifying the data, applications, and technology architectures needed to support Agency
       business processes; and
       Establishing organizational approaches that enhance the leadership and coordination of geospatial
       activities.

                                EPA GEOSPATIAL BLUEPRINT
Each of the enterprise components includes a major goal, several objectives, and action items. Timelines
for accomplishing the activities necessary to meet the goals and objectives are noted.  These proposals
were developed jointly by members of the Geospatial Blueprint Team, the OEI Geospatial Team and the
National GIS Workgroup. They are intended to serve as starting points for dialogues with the Enterprise
Architecture Teams, the Geographic Information Officer, and the Quality Information Council.

Following the body of this document are appendices that outline in detail preliminary proposals for
geospatial data, technology, and governance infrastructures for the Agency.  These proposals have been
developed based on extensive discussion with staff and managers across EPA.  The Appendices include:

                PROPOSED  EPA GEOSPATIAL  PROGRAM

The strategic goals, objectives, and activities for the EPA enterprise-wide Geospatial Program are
outlined on the following pages.  The Program envisioned will support an internal and external network
of shared, distributed geospatial data repositories and common application services which conform to
mutually accepted open standards and are based on EPA's business needs. Data and applications that can
be delivered over the Intranet and Internet via "geoservices" will be key.

The Program will enable geospatial data and applications to be used in both geospatial and non-geospatial
applications to improve overall work processes at the Agency. This section of the Blueprint outlines
current states, desired outcomes, goals, objectives, and action items for each of  the major components of
the Agency Enterprise Architecture, including business processes, data, applications, technology, and
governance.  The action items for achieving each objective under the five goals  are listed chronologically
in priority order for implementation. The lead offices for each action are also identified. Figure 1 depicts
the goals discussed in the next several pages.

  technical infrastructure that supports
access, use, management, and delivery of
 distributed geospatial data, applications,
and Web services in a seamless manner
                       Figure 1: Vision and Goals of the Geospatial Program

The time frame for accomplishing all of the goals and objectives is within the next five years. Various
activities are already underway, while some activities are dependent on the completion of other tasks, not
specific to geospatial interests. The Agency's Enterprise Architecture efforts, and in particular the
documentation of business processes and information and technology requirements to  support those
processes, are critical to understanding the role of location and geospatial data in the work of EPA. The
Geospatial Program will develop in concert with other information resources both inside and outside of
EPA, including network initiatives such as the Exchange Network, and data sharing efforts such as
Geospatial One-Stop. Table 1 summarizes the time frames for the activities of the five goals. Most action
items will have an individual project plan. The implementation of the activities will be tracked to measure
overall progress in meeting the goals of the Geospatial Program outlined in this Blueprint.

                                EPA GEOSPATIAL BLUEPRINT
                                Goal 1: Business Processes
 Improve EPA decision-making by incorporating location-based approaches, data, tools and
 knowledge into EPA business processes
Current Status and Issues

Many EPA Program and Regional offices use location-based approaches, but their focus is usually on
specific projects rather than on overall operational work processes. The Office of Water is the only
Program office that uses location as a framework for addressing almost all their programmatic
responsibilities. Region 4 has developed the South East Ecological Framework, in which geospatial data
layers are a key component.  They use this as a tool for many strategic and targeting decisions.  Most
other Programs and Regions are just beginning to recognize the usefulness of utilizing location as an
enterprise framework for their programs and using geospatial data and technologies to integrate
environmental management activities within and across media.

Desired Outcome

EPA Program Managers will understand how geospatial data, information, applications, and technologies
can be meaningfully used to enhance their business operations.  They will recognize when locational
analysis can improve their decision-making processes and they will have ready access to the geospatial
data and applications they need.

Objectives and Action Items

1.1 Foster appreciation for locational data and analyses in addressing environmental and related human
health issues.
•      Action 1.1.1: Engage EPA managers, staff, and partners in developing and maintaining the EPA
       Geospatial Blueprint. (QIC.  FY 2002-3.)
•      Action 1.1.2: Participate in EPA overarching Strategic Planning and Enterprise Architecture
       efforts to ensure the incorporation of location-based approaches. (QIC, OEI Geospatial Team
       with Program and Regional staff.  Ongoing.)
•      Action 1.1.3: Communicate and demonstrate the effectiveness of location-based analyses through
       Agency-wide newsletters, joint pilots/projects and events such as GIS Day. (GIO, and  OEI Staff
       with Program and Regional staff.  Ongoing.)

1.2 Assist EPA Program Managers to understand how locational information can support specific
business processes.
       Action 1.2.1: Identify the current and potential role of location-based approaches in two to four
       key business processes annually and develop tools as appropriate. (OIAA with program and
       Regional staff.  Ongoing.)
• •      Action 1.2.2: Identify Agency-wide needs for geospatial data, analytical tools, and products
       through a biennial survey of EPA Program offices and Regions based on their specific business
       functions. (QIC with Program and Regional staff. Summer/Fall 2003.)

                                EPA GEOSPATIAL BLUEPRINT
1.3 Assist in assessing costs and benefits of using geospatial data, technologies, and analyses to address
EPA business needs.
• •     Action 1.3.1: Conduct a Geospatial Program cost benefit analysis in support of the FY 2005
       budget. (QIC with OEI Geospatial Team, Program Offices, and Regional Offices.)
       Spring/Summer 2003.)
       Action 1.3.2: Provide templates to EPA Programs and Regions to help them examine and set
       priorities among investments in geospatial data, tools, and technologies. (OEI Staff. Fall/Winter
       2003/4.)
                                  Goal 2: Data Architecture
 Provide EPA, its partners, and the public with the geospatial data they need to carry out EPA
 business processes and make environmental decisions
Current Status and Issues

Geospatial data at EPA are often difficult to find, access, and use. Data tend to be acquired in an ad-hoc
manner, with some data sets being  purchased and stored multiple times. Regional and Headquarters
offices maintain independent geospatial libraries that are not built in such a way that they can be easily
integrated.  In addition, network access to geospatial data is difficult and the quality of the data is not well
known or communicated.  EPA does not have procedures for ensuring that locational data are collected in
a consistent and accurate manner. EPA's geospatial data partnerships with states and other federal
agencies tend to be ad-hoc and based on limited, currently available funding.

Desired Outcome

All EPA offices, partners,  and the public, will know what geospatial data EPA manages and maintains
and its quality, and will be able to find the data and metadata they need using enterprise-wide indices,
registries, or catalogs.  Regional and Headquarters offices will jointly maintain a repository so that
duplicate data purchases and unnecessary storage requirements are eliminated.  In addition, the geospatial
data reported to EPA in the course of regulatory reporting activities will be captured for future use.  Data
users will have effective means to express needs for data. These needs will be understood by senior
managers and addressed as annual budgets are developed and expended and as partnerships are
established for data with States  and other federal agencies.

Objectives and Actions

2.1 Ensure that geospatial data are accurate, well documented, and available to all users.
       Action 2.1.1: Develop options and an implementation plan for increasing the locational accuracy
       of data for which EPA is responsible or funds. (QIC Staff with Program and Regional staff.
       Spring/Summer 2003.)
• •     Action 2.1.2: Revise the EPA Locational Data Policy to include requirements that locational
       attributes and Federal Geographic Data Committee (FGDC)-compliant metadata be included
       with all geospatial data funded by EPA. (OEI Staff with LDIS.  Spring/Summer 2003.)

• •     Action 2.1.3: Establish  clear and appropriate guidance for collection and maintenance of EPA's
       locational data (e.g.  FRS and LRTs) to better address Regional and National Program Office
                                      June 2003 - page 8

       needs. (GIO, OEI staff, and LDIS. Summer/Fall 2003.)
       Action 2.1.4: Use the Enterprise Architecture business process modeling as a starting point to
       identify opportunities to obtain locational data during routine EPA business activities (e.g.,
       inspections). Develop guidance or procedures as appropriate to ensure data accuracy and a
       means to access. (Program Staff.  Summer/Fall 2003.)
• •     Action 2.1.5: Work with Program Managers to ensure key regulatory facility databases and other
       data sets (e.g., water quality standards) contain locational data adequate for their intended use.
       (GIO and Program Managers. Fall/Winter 2003.)

2.2 Provide indices/catalogs of geospatial data to facilitate use by EPA personnel.
       Action 2.2.1: Enhance the Geospatial Data Index and integrate it with other efforts such as the
       interagency Geospatial One-Stop  Initiative, EPA System of Registries, and System of Access for
       the National Environmental Information Exchange Network.  (OEI Staff. FY 2003 and then
       ongoing.)
       Action 2.2.2: Establish Agency-wide policies and procedures to ensure that information about
       the availability of geospatial data  is current, well organized, and well documented. (GIO with
       OEI and Program and Regional staff.  Winter 2004.)
• •     Action 2.2.3: Continue to identify and assess the best mix of external versus internal EPA
       solutions for accessing, acquiring, managing, distributing, and standardizing key geospatial data
       to meet Agency business needs more effectively. (GIO with OEI and Program and Regional staff.
       Winter/Spring 2004.)

2.3 Ensure that all geospatial data collected or funded by EPA are of known origin and quality.
       Action 2.3.1: Conduct peer review of "Guidance on Quality Assurance Project Plans for
       Geospatial Data" and finalize. (OEI Quality Staff with Program and Regional staff. Winter 2003)
       Action 2.3.2: Facilitate EPA Program and Regional efforts to implement the FGDC metadata
       standard (QIC with EPA Program and Regional offices. Winter/Spring 2003.)
       Action 2.3.3: Examine needs for additional metadata (e.g., feature- or transaction-based) and
       engage the Environmental Data Standards Committee and/or FGDC in considering the
       development of standards for such metadata (QIC with Program and Regional staff.  Summer/Fall
       2004.)

2.4 Participate in efforts to improve the quality and accessibility of geospatial data nationwide.
• •     Action 2.4.1: Increase participation in State and national efforts that promote more effective use
       of geospatial data for environmental decision-making (e.g, National States Geographic
       Information Council (NSGIC), FGDC, Geospatial-OneStop). (GIO and OEI Staff. Ongoing.)
       Action 2.4.2: Participate in developing extensible Mark-up Language/Geographic Mark-up
       Language (XML/GML) standards to meet EPA needs for specific geospatial themes (e.g.,
       hydrography, transportation) and provide training to ensure Agency-wide awareness of how to
       use and implement these standards. (GIO and QIC Staff.  Spring 2003  and ongoing.)
       Action 2.4.3: Set priorities for acquiring and entering into geospatial data acquisition,
       development or exchange partnerships to ensure the availability of geospatial data needed for
       EPA business. (QIC with  Program and Regional Staff. Summer/Fall2003.)
• •     Action 2.4.4 : Clarify OEI and ORD  roles and responsibilities with respect to remote sensing
       and develop a strategy for enhancing collaboration in this arena (Remote Sensing Roadmap).

                                EPA GEOSPATIAL BLUEPRINT
       Action 2.4.5: Establish standard grant and contract requirements to ensure that environmental
       data collected or developed with EPA funds are compliant with the EPA latitude/longitude
       standard and FGDC data and metadata standards. (QIC and Program Staff. Winter/Spring 2004.)
                              Goal 3: Applications Architecture
 Provide EPA staff, partners, and the public with the applications and web-services to access,
 manage,  use, analyze, present, and interpret geospatial data to conduct business and make
 environmental decisions
Current Status and Issues

There are over 70 geospatial applications in use throughout the Agency; however these are actively used
by only about 500 of the 18,000 EPA employees.  Many who could benefit from using geospatial
analyses in their work do not because they do not know of their existence or find them too difficult to
access and use without training. Many of the applications that currently exist have been created
independently in different Regions or Programs (e.g., Environmental Justice tools). Some duplication
occurs because Regions have different requirements and time frames within which they are working or
significantly different geographic conditions. Duplication also exists because there is no often no
standard Agency-wide policy or guidance for implementing national programs and slightly different tools
are developed to satisfy the implementation approach developed in specific Regions. This is compounded
by the lack of enterprise-wide search mechanisms to identify and share existing applications that might
meet multiple needs.  Additionally, requirement assessments for applications have not generally involved
a broad cross section of Programs and Regions. Where enterprise geospatial tools have been developed by
OEI, they have often focused on public access rather than internal Agency business areas. In addition,
geospatial software licenses have been difficult to track, resulting in inefficiencies in purchases and
maintenance.

Desired Outcome

EPA staff, partners, and the public will be able to identify agency applications available for manipulating
and displaying geospatial data via an enterprise index or catalog. Software will be interoperable and
based on open standards. Most of these tools will be available through desktop Web browsers, however
mobile and wireless applications will also be available for field work.  Easy to use web-based services
will significantly increase access to geospatial data and technologies by EPA Program Managers and
analysts.  Geospatial training will be available to EPA staff as needed.  As new needs for analysis are
identified, EPA offices will work together to develop the most appropriate applications drawing on
expertise from across the Agency.

Objectives and Action Items

3.1 Increase Agency-wide awareness of and access to available geospatial tools to conduct EPA business.
• •     Action 3.1.1. Develop geospatial applications that support EPA business activities. (OIAA,
       OTOP, and Program and Regional offices.  Ongoing.)
• •     Action 3.1.2. Monitor the evolution of commercial geospatial web services for possible use by
       EPA and provide recommendations to the CIO, GIO and QIC on the use and/or responsibilities

       Agency-wide access to geospatial software. (QIC with OEI, Program and Regional offices.
       Spring/Summer 2003.)
• •     Action 3.1.4. Establish and implement procedures and tools to document, inventory, and
       advertise all geospatial applications and services developed within EPA (including by states with
       EPA funding).  (OEI Geospatial Team with Program and Regional Offices.  Summer 2003.)
       Action 3.1.5. Set Agency priorities for acquiring or developing geospatial applications in annual
       budget and operating plan processes using results of the biennial survey process (see action
       1.2.2). (OIAA with Program and Regional offices. FY 2004 then ongoing.)
• •     Action 3.1.6. Establish criteria for evaluating potential software acquisitions, including the ability
       of the product to meet EPA functional needs. Conduct bench-marking analyses as necessary.
       (OTOP with Program and Regional offices. FY 2004 then ongoing.)

3.2 Incorporate open and interoperable standards when developing EPA geospatial tools.
• •     Action 3.2.1: Participate in industry efforts and public-private partnerships to develop open
       specifications. (OEI Offices and Program and Regional offices.  Ongoing.)
• •     Action 3.2.2: Design and implement effective means to access and use open source code for
       geospatial applications. (OEI Staff.  Ongoing.)

3.3 Provide EPA staff with access to training needed to use geospatial tools as effectively.
       Action 3.3.1: Identify employee training needed for various geospatial tools. (OEI Staff. Fall
       2003.)
       Action 3.3.2: Develop a Geospatial Training and Workforce Development Plan. (OEI Geospatial
       Team with Program and Regional offices.  Spring/Summer 2004.)
• •     Action 3.3.3: Implement the Geospatial Training Plan. (OEI Offices with Program and Regional
       offices. FY04.).
                              Goal 4: Technology Architecture
 Design and implement an enterprise-wide technical  infrastructure that supports access, use,
 management, and delivery of distributed geospatial data, applications,  and Web services in
 a seamless manner
Current Status and Issues

EPA's geospatial activities are currently supported by a diverse array of handheld devices, personal
computers, servers, and networks which were documented in the Geospatial Baseline (2001). EPA's
technical infrastructure1 was originally designed to support individual and independent applications,
without considering needs for enterprise-wide data exchange. While the current configuration supports
many distributed users, EPA Regions and Program offices often have difficulty accessing and sharing
data due to limitations in both network configuration and capacity. In some cases, network bandwidth
within offices is significantly less than between offices across the country, creating challenges for inter-
regional, headquarters, and National Computer Center exchanges.  In addition, EPA security concerns
have created new challenges in sharing  data with external partners.  Use of Web tools and technology to
        A technical infrastructure includes hardware, operating systems, software, and networks.

deliver GIS and other geospatial products is generally restricted to those offices with significant funding
and the ability to navigate difficult technology and administrative hurdles.

Desired Outcome

EPA staff will be able to access, process, and manage geospatial data needed at any time to accomplish
their operational responsibilities, including sharing the data with EPA partners. EPA information
technology managers will have a clear understanding of all components of the technical infrastructure and
how to optimize performance. Managers will be able to add, delete, and/or replace components of the
architecture as needed based on compliance with open standards. Specific field sites will be able to
provide GIS and other geospatial products via the Web. This will enable innovation by Program and
Regional offices that can be scaled up for broad audience use as appropriate.

Objectives and Action Items

       Action 4.1.4: Implement the EPA Geospatial Network based on work completed under actions
       4.1.1 and 4.12. (OEI/NTSD  with Regions and Programs. FY2003-4.)
       Action 4.1.5: Ensure that all nodes within the EPA geospatial network are properly staffed and
       fully operational. (GIO, QIC, and OEI Staff.  Winter FY 2003-4 and ongoing)
       Action 4.1.6: Provide access to equipment and training for inspectors and other on-the-ground
       staff to help them  collect geospatial data in the course of their regulatory and monitoring
       activities. (OEI  Staff.  FY 2004 and then Ongoing)

4.2  Ensure that the security of EPA geospatial data and applications is protected, while allowing
appropriate exchanges of data with partners and stakeholders.
• •     Action 4.2.1: Establish network protocols to allow the exchange of geospatial data with external
       users, coordinating such efforts with the Agency's broader EA and NEIEN activities as
       appropriate. (OEI Geospatial Team with Program and Regional offices. FY 2003.)
       Action 4.2.2: Establish secure Web-services that enhance the ability to share EPA data and tools
       with external partners via the internet and extranet. (OIAA, OTOP, and Program and Regional

4.3 Build the EPA geospatial technology architecture based on open standards that foster interactions
with other partners and the timely implementation of emerging technologies.
       Action 4.3.1: Increase EPA participation in standards testing and protocol development with the
       Open GIS Consortium, Inc. and other industry-public sector consortiums to ensure open

       interoperability of hardware components. (OTOP/NTSD with Program and Regional offices.
       FY2004-5)
                              Goal 5: Governance Architecture
 Establish an effective governance structure for setting priorities for geospatial investments,
 coordinating  geospatial efforts, and communicating how geospatial data and technologies
 are used within the Agency
Current Status and Issues

Regions, Programs, ORD, and OEI offices make independent investments in geospatial data, applications,
and technologies with only a partial understanding of other agency geospatial efforts. In some cases this
results in inefficiencies and duplication. Offices needing assistance in geospatial activities do not know
where to turn for full support.  Specific roles and responsibilities are not clear, and offices, to some
extent, compete for resources.  Standards are developed that are not used or enforced, and in other
situations potentially valuable standards have not been identified and adopted. Existing coordination
efforts (e.g. National GIS Workgroup) tend to focus on technical solutions and information exchange,
rather than joint application project definition and management or planning for future needs. Partnership
interactions tend to be ad-hoc and uncoordinated.

Desired Outcome

The leadership and governance structure for geospatial activities will be clearly articulated. It will provide
guidance and coordination in setting priorities and pursuing investments. Managers, users and potential
users of geospatial technology understand their responsibilities, know where to turn for assistance, know
how agency geospatial investment priorities are being decided, and have opportunities to provide input
into the process. Agency guidelines and standards, based on interoperability, for collecting, documenting,
and managing geospatial data will be implemented. Trends in geospatial technologies and EPA
geospatial activities will be examined at least every other year and decisions will be made about
directions and priorities.  Nearly all of EPA data investments will be pursued in strategic partnership with
other federal, state, and private sector entities.

                                      NEXT STEPS
Several actions outlined in this Blueprint have already been initiated.  Staff and managers across the
Agency have gained far more understanding of how EPA uses geospatial data and what the potential for
geospatial technologies is in the organization. The GIO position has been advertised and applications
received.  Discussions about configurations for hardware and data have been initiated and a governance
plan has been drafted. Finally, the Agency's Locational Data Policy is being  revised as EPA examines
the quality of locational information across various programs.

Critical next steps include hiring a GIO and initiating the various actions in this Blueprint. The actions
will provide a guide for conducting a return on investment analysis, as well as outlining budget and
operating plans. The GIO will provide the leadership necessary to implement the actions in an effective
and timely manner.  The Blueprint will continue to be used to inform the Enterprise Architecture effort
and will assist in ensuring that geospatial activities and needs are recognized as the Architecture is built
out. Deploying a geospatial network capable of supporting web-based geoservices will be a key priority
on the next FY.  As sequencing plans for other information initiatives are developed such as Central Data
Exchange, Enterprise Repositories, System of Access, and Exchange Networks, this Blueprint will
provide guidance for addressing where and how geospatial efforts support and benefit from those
activities.

The governance proposal will be reviewed, discussed Agency-wide, modified as necessary and
implemented so that investments and actions carried out meet enterprise needs. Data requirements will be
more fully examined as part of the EA efforts implemented by the programs and regions in FYs 2003-
2004. Data stewardship responsibilities will be identified as requirements are finalized and priorities for
meeting these requirements set through the agreed upon governance structure.

These coordinated efforts will ultimately result in the ability to effectively and efficiently collect, access,
interpret, and use geospatial data and technologies to make better environmental decisions. This is the
vision of the Geospatial Program.

      Appendix B: Definitions of Commonly Used Geospatial Terms

Aerial Photography: The method of taking photographs from an aerial platform (aircraft). 1) Vertical
photography, some times called orthophotography (see entry) is used for photogrammetric mapping and
requires a high degree of accuracy.  2) Oblique photography is used for general information, sometimes to
verify certain attributes, but does not provide accurate measurements for photogrammetric mapping.

Bandwidth: The term bandwidth in computer networking refers to the data rate supported by a network
connection or interface. One most commonly expresses bandwidth in terms of bytes per second (bps). The
term comes from the field of electrical engineering, where bandwidth represents the total distance or
range between the highest and lowest signals on the communication channel (band).

DBMS:  Stands for database management system. A DBMS provides the means to store and manage data.

Distributed, Networked Hardware: Servers and clients distributed throughout an organization and
connected via the Internet, Extranet, or Intranet to allow processing on and access to and from multiple
platforms.

Enterprise: The enterprise is EPA and its partners in environmental protection.  Enterprise activities are
those efforts that further the broad needs of EPA and its partners. Geospatial enterprise efforts include the
data, services, technology, and expertise that will most effectively meet the most common needs of the
most people. An "enterprise approach" is intended to minimize duplication, and foster integration and
consistency, while still promoting innovation. An enterprise approach for managing geospatial data,
technology, and services will not necessarily address every geospatial need within the Agency or between
EPA and its partners.  Enterprise Architecture is defined by the federal ClO-Council to be a
comprehensive series of principles, guidelines, models, diagrams, and standards that:
    depict the existing business, information flows, data, applications, and technology;
•   describe the potential impacts of business and technology change drivers on the enterprise;
    recommend a target environment for the enterprise that is aligned with its business and data needs and
    incorporates overarching processes such as quality and asset management, IT investment, and
    security management;
•   identify a technical reference model (TRM)  and standards profile; and
    include a sequencing plan to guide migration from the baseline (current state) to the target
    architecture.

The Federal Geographic Data Committee ("FGDC"): coordinates  the Federal Government's
development of the National Spatial Data Infrastructure. FGDC was established by the Office of
Management and Budget ("OMB") Circular No. A-16  ("Coordination of Surveying, Mapping, and
Related  Spatial Data Activities") and chaired by the Secretary of the Department of the Interior
("Secretary") or the Secretary's designee.

Framework Data: Term used by the FGDC in development of the NSDI that describes the data layers
most commonly needed and used by most users  in the development and use of geographic analyses.
These layers often form the base to which other  data are attached.  The FGDC defined the following
seven framework data sets as a means to identify priorities for data collection, but recognizes that many
other data sets may be critical for specific agency analyses,  including EPA.  The agencies primarily
responsible for organizing these data on a national basis are noted in parenthesis.

•   Digital orthoimagery (Department of Interior (DOI) - United States Geological Survey (USGS)):
                                     June 2003-page 19

-------
                                 EPA GEOSPATIAL BLUEPRINT
    This data set contains geo-referenced images of the Earth's surface, collected by a sensor. Digital
    orthoimages have the geometric characteristics of a map and image qualities of a photograph.
    Cadastral data (DOI - Bureau of Land Management (BLM)): This dataset describes the geographic
    extent of past, current, and future right, title, and interest in real property, and the framework to
    support the description of that geographic extent.  The geographic extent includes survey and
    description frameworks such as the Public Land Survey System, as well as parcel-by-parcel surveys
    and descriptions.
    Geodetic control (Department of Commerce (DOC) - National Geodetic Survey (NGS)):  Geodetic
    control provides a common reference system for establishing coordinates for all geographic data.
•   Elevation (DOI - USGS and DOC - National Oceanic and Atmospheric Administration (NOAA)):
    This data contains geo-referenced digital representations of terrestrial surfaces, natural or manmade,
    which describe vertical position above or below a datum surface.
•   Hydrography (DOI - USGS): This data theme includes surface water features such as lakes, ponds,
    streams, rivers, canals, oceans, and coastlines.
    Transportation (Department of Transportation (DOT) - Bureau of Transportation Statistics (BTS)):
    Transportation data are used to model the geographic locations, interconnectedness, and
    characteristics of the transportation system within the United States.  The transportation system
    includes both physical and non-physical components representing all modes of travel that allow the
    movement of goods and people between locations.
    Government units (DOC - United States Census): These data describe, by a consistent set of rules
    and semantic definitions, the official boundary of Federal,  State, local, and Tribal governments.

Geospatial data: Geospatial data are defined as any data that are referenced to a location on the surface
of the earth.  This term is often used in place of other terms such as maps, geographic data, or spatial data.
It also includes individual point or site specific data that are referenced to a location on the earth and
digital aerial imagery of the earth.

Geospatial Data Index (EPA):  A system of XML web services providing the user access to metadata
records  about spatial data (layers) stored in various spatial  data servers throughout the EPA. This web
site allows internal users to search for, locate and obtain geospatial data, and other related information.
The index supports access to and maintenance of FGDC compliant metadata.

Geospatial technologies: Geospatial tools and technologies describe the combination of hardware and
software that are commonly used to collect, import, store, manipulate, analyze, and display  digital
geospatial data. These technologies include geographic information systems (GIS), georeferencing tools
(global positioning systems - GPS), remote sensing, and visualization systems.

Geospatial One-Stop: One of 24 OMB electronic-government initiatives that will enhance government
efficiency and achieve the vision that government be more citizen-based and results oriented. Geospatial
One-Stop will build on investments already made to develop a National Spatial Data Infrastructure
(NSDI)  and advances in geospatial information technologies to encourage greater collaboration and
coordination in their use across all levels of government.

Geoservices: Internet Geoservices are Internet Services that can be requested with a geographic
reference or parameter imbedded in the requesting media such as a URL or XML  file. The concept here is
that an enterprise can share all its our data and applications as long as they are published as  Web services.
These Internet Geoservices can be used separately or in concert with each other, sometimes referred to as
cascading or aggregate services. These include but are not limited to:

•   Geodata services: Will generate a geospatial data file that can be 'streamed' to an Internet enabled
                                      June 2003 - page 20

-------
                                 EPA GEOSPATIAL BLUEPRINT
    application. The NWIS access illustrated in WME is an example of a Geodata Service. WME sends
    a request to the USGS NWIS Web service for  an XML file of NWIS data using the coordinates of
    the 'window' for the request.
•   Georeporting services: These are typically HTML reports that can be requested with some specified
    geography in the request string. WME's 'Your Environment' tab is dominated by georeporting
    services.
•   Geomapping services (Web mapping services): Allows the users to print out or view a map of
    consisting of user selected geospatial data layers. WME is an example of a Geomapping Service.
•   Geographic Interface services: Will generate a complete interface or a component of an interface to
    other Internet Geoservices. EnviroMapper is an example of a geographic interface service.
•   Geometadata Service: - Internet services that provide access and dissemination of metadata for
    geospatial information. Metadata are a means to determine the content and suitability of data that
    may be desired to be accessed by GIS users. Geospatial Metadata Services are web services that
    provide catalogues, search capabilities and  links to both the geospatial metadata and data they
    describe.
•   Geoprocessing/Geoanalysis Service: Allows the users to put environmental data into a
    georeferenced format or generate assessments with the geospatial data available. Examples include
    geocoding,(E.g  the user inputs a  street address and a - latitude/longitude value is calculated for that
    address) buffering, and networking/routing.

Geographic Analysis:  GIS aids in analyzing geographic data. Geographic analysis uses the geospatial
properties of features to look for patterns and trends, and to undertake "what if scenarios. The most
common forms of GIS analyses include Proximity Analysis and Overlay Analysis.

Geographic Information Systems (GIS): Computer system designed to allow users to collect, manage,
and analyze large volumes of spatially referenced and associated attribute data. GIS's are used for
solving complex research , planning, and management problems.  The major components of a GIS are: a
user interface, system /database management capability, database creation/data entry capacity, spatial data
manipulation and analysis package, and display generation capacity.

Geospatial Network (EPA): A virtual network consisting of one central node and multiple regional
nodes connected via the EPA intranet that will allow the sharing of geospatial data, applications and
services throughout the EPA.

Global Positioning System (GPS): A system developed by the U. S. Dept. of Defense that is based on a
group of 21 satellites orbiting the earth at very high altitude. GPS receivers are inexpensive and small.
GPS is the technology used in  vehicle navigation systems.

Imagery:  Visible representation of objects and (or) phenomena as sensed or detected by  cameras,
infrared and multi-spectral scanners, radar, and photometers. Recording may be on photographic
emulsion or on magnetic tape for subsequent conversion and display on a cathode ray tube.

Interoperability:  The capacity of different systems or components to interact and work together. For
instance, two interoperable software systems seamlessly share information and can be "chained" or
"connected" to work together as a unified software system.

Land Cover: What can be seen on the landscape - essentially the vegetation and other physical
characteristics. Land cover is often mapped using remotely sensed data as cover types can be delineated
based on appearance or their spectral reflectance.
                                      June 2003 - page 21

-------
                                EPA GEOSPATIAL BLUEPRINT
Land Use:  How land is managed for human purposes. Land use is generally locally regulated in the U.S.
based on zoning and other regulations. Land use mapping differs from land cover mapping in that it is
not always obvious what the land use is from visual inspection.

Layer:  is a subdivision of a CAD or GIS database containing related data. Layers can be visualized as
"transparencies" which allow the user to view and analyze information selectively by theme.  Some GIS
build their databases as a series of layers covering a single area. Layers are fundamental to overlay
analysis.

Locationally referenced data: Tags on point or site specific data that are referenced to a coordinate or
address on the surface of the earth. (This may also be referred to as locational data.)

Map: A representation of a portion of the earth, usually drawn on a flat surface. (From Latin
mappa, a napkin, sheet or cloth upon which maps were drawn.)

MRLC: Multi-Resolution Land Characteristics Consortium is an organization formed in  1992 among
several federal agencies agreed to acquire satellite-based remotely sensed data for environmental
monitoring programs. Original members of the Multi-Resolution Land Characteristics (MRLC)
consortium were the U.S. Geological Survey (USGS), Environmental Protection Agency  (EPA), National
Oceanic and Atmospheric Administration (NOAA) and the U.S.  Forest Service (USFS) . Later joining the
consortium were the National Atmospheric and Space Administration  (NASA) and the Bureau of Land
Management (BLM). During the 1990's, the MRLC resulted in several successful mapping programs,
including the: (1) Coastal Change Analysis Project administered by NOAA; (2) Gap Analysis Project
directed by the USGS Biological Resources  Division, and the National Land Cover Data (NLCD) project
directed by both the USGS and EPA. The data developed by these projects are available publicly via the
Web or by contacting the agencies involved.
National Geospatial Data Clearinghouse:
managers, and users linked electronically.
a distributed network of geospatial data producers,
National Spatial Data Infrastructure ("NSDI"): The technology, policies, standards, and human
resources necessary to acquire, process, store, distribute, and improve utilization of geospatial data.

N-Tier: An application program is distributed among three or more separate computers in a distributed
network. The most common form of n-tier (meaning 'some number of tiers') is the 3-tier application, in
which user interface programming is in the user's computer, business logic is in a more centralized
computer, and needed data is in a computer that manages a database. N-tier application structure implies
the client/server program model. Where there are more than three distribution levels or tiers involved, the
additional tiers in the  application are usually associated with the business logic tier.)

Open Standards for  GIS Software: Common protocols on how GIS information is presented to ensure
various systems "talk to each other."
Overlay Analysis: The integration of different data layers involves a process called overlay. At its
simplest, this could be a visual operation. For example, the question: "Does Palmer Colonia lie within a
100 year floodplain?" can be answered by overlaying a flood plain map on a Colonia boundaries map.

Platform: is a another term for computer hardware, including microcomputers, workstations, and
mainframe computers. When discussing software, platform independence implies the software can be run
                                      June 2003 - page 22

on any computer.
Points: Items such as oil wells, utility poles, etc. Specific objects with exact location noted usually by
latitude and longitude.

Polygon: Irregularly shaped area that conforms to the boundaries of some characteristic being
mapped (fire protection districts, vegetation type, elevation, etc.)

Precision: The degree of refinement in the performance of an operation, or the degree of
perfection in the instruments and methods used when making the measurements. A measure of the
uniformity or reproducibility of the result. Precision relates to the quality of the operation by which a
result is obtained, and is distinguished from accuracy which relates to the quality of the result.

Proximity Analysis: GIS is often used to answer such questions as
•   How many houses lie within 100 m of this water main?
•   What is the total number of customers within 10 km of this store?
•   What proportion of the citrus crop is within 500 m of the well? To answer such questions, GIS
    technology uses a process called buffering to determine the proximity relationship between features.

Portal (enterprise):  single Internet location through which users can gain access to multiple sources of
information and services. A centralized portal offers "one stop shopping". With respect to geospatial
Information is presented in a manner that would be increase the effectiveness of the centralized portal e.g.
by tagging all geospatial data to make it readily searchable.)

Remote Sensing: (From the American Society of Photogrammetry and Remote Sensing) "The art,
science, and technology of obtaining reliable information about physical objects and the environment,
through the process of recording, measuring, and interpreting imagery and digital representations of
energy patterns derived from non-contact sensor systems". Photography is a form of remote sensing.
Satellites are a remote sensing platform that collect nearly real-time or periodic imagery for conducting
analyses of land cover and land forms based on spectral signatures of various features on the earth.

Thick client:  Computer (often desktop) that has full functionality to store and run  applications and
manipulate data, including input devices (e.g., CD ROM, disk drives), but is connected to a server. Most
applications will be run on the computer rather than the server, although data may be accessed from the
server.

Thin Client: Low-cost, centrally-managed computer that does not include many applications, data or
input devices (e.g., CD-ROM players, diskette drives, and expansion slots). These computers have limited
capabilities and will only run essential applications. "Server-based computing"  may be used as a
synonym for "thin client" because most thin clients today are powered by back-end centralized servers
that are capable of serving either "thick" or "thin" clients.
TIGER: Acronym for Topologically Integrated Geographic Encoding and Referencing (Street
network files). TIGER data is an automated, single source geographic database of street network
files developed for the 1990 census.

Vectors: Lines defined by "x", "y" and "z" coordinate endpoints. Roads, rivers, contour lines, etc.
presented as vector lines.

                                EPA GEOSPATIAL BLUEPRINT
Visualization: For many types of geographic operation the end result is best visualized
as a map. Maps efficiently store and communicate geographic information. While cartographers have
created maps for millennia, GIS  provides new and exciting tools to extend the art and science of
cartography.

Web Services: Loosely coupled, reusable software components that semantically encapsulate discrete
functionality and are distributed and programmatically accessible over standard Internet protocols. (The
Stencil Group (http://www.stencilgroup.com/ideas_scope_200106wsdefined.html#whatare)

XML/GML:  XML (Extensible Markup Language) is a flexible way to create common information
formats and share both the format and the data on the World Wide Web, intranets, and elsewhere. XML,
a formal recommendation from the World Wide Web Consortium (W3C), is similar to Hypertext Markup
Language (HTML). Both XML and HTML contain markup symbols to describe the contents of a page or
file. HTML, however, describes the content of a Web page (mainly text and graphic images) only in terms
of how it is to be displayed and how to interact with it. For example, the letter "p" placed within markup
tags starts a new paragraph. XML describes the content in terms of what data is being described. For
example, the word "phonenum" placed within markup tags could indicate that the data that followed was
a phone number. This means that an XML file can be processed purely as data by a program or it can be
stored with similar data on another computer or, like an HTML file, it can be displayed. XML is
"extensible" because, unlike HTML, the markup symbols are unlimited and self-defining. GML or
Geography Markup Language is an XML encodes the geometry and attributes of geographic information
for transfer and storage of geographic information.

            Appendix C:  Proposed EPA Geospatial Data Architecture
As part of both the Geospatial Activities Baseline Assessment and Geospatial Blueprint efforts, initial
conversations were held with Regional and Program Office employees about the geospatial data
necessary to support their program needs. Additionally, the OEI/Office of Information Collection and
Region 3 jointly explored a prototype geospatial data planning process that involved identifying
geospatial data needed to support key Region 3 business activities. The information obtained from these
efforts served as the basis for developing a preliminary list of the geospatial data sets required to
effectively support implementation of business operations Agency-wide.  This list will be the starting
point for more in-depth conversations with Program and Regional offices to identify the  data that will
comprise the geospatial component of the Enterprise Repository. These conversations will be held with
both the Program and Regional offices  as part of the Enterprise Architecture effort currently underway.

These enterprise geospatial data sets will only reside on EPA servers when it is not possible or practical to
access the geospatial data from their original sources - the other Federal, state, local geospatial data
servers that are part of the National Spatial Data Infrastructure (NSDI). For example, in  the long term
data and applications users will directly access the USGS master files for National Hydrography Dataset
(NHD), National Elevation Dataset (NED), National Land Cover Dataset (NLCD), and the National
Watershed Boundary Dataset (NWBD).  The government-wide Geospatial One-Stop will support this
type of access. EPA geospatial data sets will also be accessible to others within security constraints via
Geospatial One-Stop.

The geospatial data sets that are part of the EPA Enterprise Architecture will reside on distributed servers
within the National Computer Center (NCC), Regions, and Programs. Regional integrated geospatial data
servers, and Program and ORD laboratory integrated geospatial data servers will comprise this repository
as a network of data servers. The servers will be organized consistently with data formatted according to
FGDC standards. Users of data will be able to access multiple servers transparently and  seamlessly (See
Figure D-2).  All data will be known through the Geospatial Data Index.

Discussions over the next year will determine optimal allocation of data sets based on resources available
to support access, resolution, and use of the data, and needs for site specific integration. Geospatial data
that are needed by more than one office will have identified "stewards" responsible for ensuing data
availability and documented quality.  In some cases, data may be duplicated across servers for security
reasons.  Data for public access will be maintained on separate server. Not all EPA data will be
publically accessible.  Table C-l lists the various data sets identified as needed by EPA employees.

Initial Agency discussions have outlined specific responsibilities for ensuring the reliability of and access
to needed geospatial data within EPA. Table C-2 makes the distinction between small scale (e.g., equal to
or smaller than 1:100 K scale) national data and regional or site specific data which exist at larger scales
and are often not complete for the nation. Georeferenced and Programmatic data represent EPA specific
data.  Data stewards are individuals who will report on the availability of data to the GDI, as well  as tend
to the quality of the data.

       Appendix D:  Proposed Technology Architecture to Support
                   Geospatial Applications and Data Access


As previously discussed, geospatial data and technologies are recognized as key components of the
overall EPA Enterprise Architecture. No place is this more prevalent than in the technology component.
The same hardware will support geospatial functionality, word processing, database management, and so
forth. The primary technology challenge in the use of geospatial data tends to be network capacity. Over
the last year members of the OEI Geospatial Team and Geospatial Blueprint Team have been working
closely with the Enterprise Architecture team to ensure coordination in goals and objectives, and
recognition of unique geospatial processing requirements.

Figure D-l schematically depicts the geospatial components of the Enterprise Architecture at EPA. The
drawing illustrates how the geospatial elements fit into the other key enterprise components under
development.  This drawing highlights the geospatial pieces and provides considerably less detail on the
other components. The diagram will be used as a starting point in discussions with EPA staff designing
other enterprise components and in developing the integrated project and sequencing plans for the OEI
components of the Environmental and Public Heath Protection Architecture (to be initiated in the spring
of2003).

    	I Denotes components of the virtual Geospatial Network

As part of the Geospatial Blueprint planning effort, members of the OEI Geospatial Team and National
GIS Workgroup have jointly defined and proposed a preliminary design for the Geospatial Technical
Architecture. The EPA Geospatial Network (See Figure D-2), comprised of geospatial data, applications,
and technologies, is designed to be integrated within the Enterprise Architecture through the System of

-------
                                    GEOSPATIAL BLUEPRI
Access, CDX, System of Registries, and Enterprise Repository. The Geospatial Network will significantly
improve and simplify the exchange and sharing of GIS databases and applications among Regional and
Program Offices, Research Laboratories, and the NCC. It will utilize Web Services and new technologies
to improve efficiency, minimize duplication; and save costs.

The Network, which is comprised of a series of NCC, Program, laboratory, and Regional Nodes consists
of linked data and application servers. This configuration will enable each node to provide geospatial
data, metadata, analytical and/or application Web Services.  Each node will have a standard minimum
level of functionality/performance which will include requirements for comprehensive, current, metadata

for all datasets. These nodes will represent components of the overall Agency Enterprise Architecture
and will support metadata that may be stored locally or within EIMS, but in both cases accessible through
a Geospatial Data Index as part of the Enterprise Architecture and the Geospatial Network. XML/GML
and SVG open standards will be the basis for transporting data. FGDC and Agency standards will be
required, and national and international standards will tie the Geospatial Registries within the System of
Access to facilitate discovery and access to the data. Figure D-2  provides additional details on the
components and flows relative to geospatial data and highlights the different infrastructures needed to
respond to different users and levels of security. The dark blue arrows represent the general public, with
access to some, but not all EPA data. The dark red lines show EPA users and/or their partners who have

Utilizing existing and proposed communications hardware (routers, Tl and T2 lines, switches, WAN and
LAN), the Geospatial Network will be physically integrated with the rest of the Agency
telecommunications infrastructure, but will provide a virtual geospatial network.  The virtual network will
allow Regional, Program, and Research Laboratories to host the geospatial data related to their local
environmental protection activities. This provides these offices the means to manage the data they need
most. The local hosting will allow Regional, Program and Research Labs to efficiently conduct
geospatial analysis, create maps, update databases, and create new data and application performance.
Minimizing the separation for the local/specialized data used primarily by these offices maximizes the
resources at the local site and reduces the bandwidth load over the network for the entire Agency.
National data sets will be hosted on the NCC node; however, over time base coverages (such as NED,
NALC, MLRC) will be retrieved from the host agency via established connections such the Geospatial
One-Stop Portal. Data replication requirements will need to be established as they pertain to security and
disaster recovery. Data utilization (who, what, when, how often) will be a determining factor for where
data are hosted.

Web services will be developed and deployed across the Geospatial Network. These Web services will
provide the various levels of data access required by the users. Web services will provide  users with tools
and applications to assist in metadata creation, cataloging, querying, and analysis.

In early November 2002 a survey was sent to EPA Programs and Regions to help determine the
architectural requirements and resource needs for the nodes on the Geospatial Network.  Issues that were
raised included:
       Level of service required of each node on the network
•       Capacity to participate
       Architectural options and tradeoffs for deployment (e.g., distributed, centralized, mixed)
•      Requirements to support distribution
       Long term support needs
•      Keeping pace as technology changes
        Organizational issues

The results of this survey have been posted to the National GIS Workgroup web site for use in developing
node requirements and as input to the overall EPA Enterprise Architecture effort. Based on these results
the NCC staff developed a list of proposed hardware and software components for each node on the  EPA
Geospatial Network (Table D-l)  The Geospatial Network is currently being built with available
equipment (hardware/software) at both the NCC and the Regional Sites.  This ad hoc construction will not
guarantee the level of performance and capacity necessary to sustain EPA geospatial needs, but will
provide the initial proof of concept and a test platform for further functionality and utility. For more
information on how and why the Geospatial Network will utilize a Regional node configuration, please
refer to document "Recommendation on Building a Geospatial Node in EPA Regional Offices" (April
2003) posted on the National GIS Workgroup web page.

The Regional Node Survey provided the base information about the current physical makeup and
available resources that could  be utilized to construct each Regional node.  The results of the survey
showed that most Regions have the required software licenses to support an initial rollout of the
Geospatial Network.  The largest shortfall is believed to be on the hardware side. Further investigation is
needed to catalog the system specifications of the available equipment and run a comparison against the
recommended standard configuration specifications. The second shortfall is in trained personnel to
support a distributed database  that will be accessible across the network. This represents a training need
for Regional, Program and Research Laboratory personnel in database management skills and tools.  Most
of these individuals have general GIS knowledge and skills and have access to other personnel with
database management skills, but they lack the overall data hosting and spatial database skills.

The next steps for training GIS personnel in the Regions will consist of the following:
        1.      GIS personnel will attend general vendor-offered GIS training courses relating to Oracle
               Spatial Database administration, ArcSDE, ArcIMS and Windows2000 administration.
        2.      OEI Geospatial Program Support will create and conduct a basic geospatial node
               development and administration course (specific to EPA environment).
        3.      OEI Geospatial Program Support will conduct on-site support and hands-on training
               visits to each region developing a node.

The vendor-offered training will provide base knowledge and skills. The training provided by the OEI
Geospatial Program support will provide knowledge on applying vendor software within the unique EPA
geospatial environment. The on-site visits will provide tailor-made solutions and training required by
each site. Additional information on this approach can be obtained from the document "Recommendation
for Building a Geospatial  System for EPA Regional Offices" (April 2003) which is posted on the
National GIS Workgroup  Website.

The NCC node will need considerable upgrading to enable hosting large national datasets, applications,
tools and connection services. Presently, there is no hardware available to begin construction. The UNIX
server is the largest and most crucial piece of hardware required by the NCC node. The central node will
be responsible for hosting a large quantity of data for the agency, acting as temporary (possibly
permanent) host for Regional data until Regional nodes can be built, hosting national Web services and
tools, and facilitating connections between all geospatial nodes. Without a strong central node,
performance and communication will be severely affected.  The Geographic Data Index (GDI),
Environmental Information Management System (EIMS) and the Integrated Geospatial Database (IGD)
will be integrated and/or linked into the NCC central node once the hardware is in place. The linking of
these  systems into the NCC node will provide all users a permanent and continuous connection to GDI,
EIMS, and IGD. The linking will also allow developers to create applications that access these systems
directly. The OEI Geospatial Team will continue to solicit cooperation from other geospatial data owners
for inclusion in the network.

Trusted partners will be able to access EPA data via the Geospatial Network. Controls will be in place
that will allow access to approved data sets.  Controls can also be set up to allow only a certain type of
access (view, download, read/write, etc.).

The dialogs on the geospatial technoloy architecture/Geospatial Network and the resulting proposals are
considered a tool to work with those responsible for designing and implementing the broader EPA
Enterprise Architecture.  The proposed Geospatial Network will work within the Enterprise Architecture
in concert with the System of Access, the Enterprise Repository, and the System of Registries, and CDX.
The proposed diagrams and specifications will be used as a starting point for working with others who are
currently developing overall project plans and sequencing plans for the Environmental and Health
Protection architectures.  Over the next 3-6 months the following activities will be undertaken to complete
the design and cost assessment for the proposed geospatial network to prepare for these dialogues.

•  Work closely with the EPA's wiring upgrade effort to ensure that the telecommunications network
   will provide adequate bandwidth for the Geospatial Network.
•  Catalog existing Regional and Program geospatial equipment and compare against the recommended
   standard configuration specifications to determine investments needs.
•  Finalize skill mix necessary to maintain and operate a node on the Geospatial Network
   Investigate the FTE requirements of all locations supporting the Geospatial Network and provide
   possible solutions and/or options to meet these requirements.
   Revisit the training requirements issue to ensure that GIS personnel have the necessary skills.
•  Generate the finalized costs and incremental funding necessary to fully implement the proposed
   Geospatial Network.
•  Examine issues associated with external access to the EPA Geospatial Network and propose
   approaches  for secure access.
•  Develop a cost-benefit analysis document for this proposal in coordination with enterprise
   architecture efforts.

             Appendix E:   Proposed  EPA Governance Architecture


Participants in the Geospatial Blueprint effort placed a high priority on establishing a strong focal point
for coordinating geospatial efforts Agency-wide and clarifying the roles and responsibilities of OEI,
Programs, and Regions. Numerous discussions on roles and responsibilities were held with members of
the Geospatial Blueprint Team, the National GIS Workgroup, and the OEI Geospatial Team between
November 2001 and March 2002. The recommendations from these discussions are summarized in
Tables E1-E3 of this Appendix.

The Assistant Administrator for Environmental Information charged several EPA staff from OEI, the
Programs, and Regions to propose a governance structure for EPA geospatial activities at the end of 2002.
The information contained in this Appendix was used as  a starting point to develop a proposal on the
scope and functions of a Geospatial Governance Group.  The draft Geospatial Governance Group
proposal was submitted to OEI senior management for review in March 2003.
