Approved on January 6, 2006 by the
Chief Information Officer of the

under the guidance of the Exchange Network Leadership Council and its predecessor organization, the
Environmental Data Standards Council.

Latitude/Longitude
Data Standard
Std No.:EX000017.2

Foreword

The Environmental Data Standards Council (EDSC) identifies, prioritizes, and pursues the creation of data
standards for those areas where information exchange standards will provide the most value in achieving
environmental results. The Council involves Tribes and Tribal Nations, state and federal agencies in the
development of the standards and then provides the draft materials for general review. Business groups, non-
governmental organizations, and other interested parties may then provide input and comment for Council
consideration and standard finalization. Standards are available at http://www.epa.gov/datastandards.

1.0	INTRODUCTION

The Latitude/Longitude Data Standard is a set of data elements that can be used for recording horizontal and
vertical coordinates and associated metadata that define a point on the earth. The latitude/longitude data
standard establishes the requirements for documenting latitude and longitude coordinates and related method,
accuracy, and description data for all places used in data exchange transaction. Places include facilities, sites,
monitoring stations, observation points, and other regulated or tracked features.

1.1	Scope

The purpose of the standard is to provide a common set of data elements to specify a point by latitude/longitude.

This standard describes data elements and data groupings that are used to exchange Latitude/Longitude data
and information.

Environmental Data Standards Council adoption of the revised
standard, format and content changes, added examples values,
and renumbered the standard.













1.3 References to other data standards

This standard relies on two other standards to make it complete and provide the necessary support. As such,
users should reference the normative standards listed below and consider them integral to the
Latitude/Longitude Standard. These include:

• Representation of Date and Time [EX000013.1] Data Standard

Measure [EX000010.1] Data Standard

1.4	Terms and Definitions

None

1.5	Implementation

Users are encouraged to use the XML registry housed on the Exchange Network Web site to download schema
components for the construction of XML schema flows (http://www.exchanqenetwork.net').

1.6 Document Structure

The structure of this document is briefly described below:

a.	Section 2.0 Latitude/Longitude Data Structure Diagram illustrates the hierarchical classification of the

Latitude/Longitude data standard. This diagram enables business and technical users of this standard
to quickly understand its general content and complexity.

b.	Section 3.0 Latitude/Longitude Data Standard Table provides information on the high level, intermediate

and elemental Latitude/Longitude data groupings. Where applicable, for each level of this data standard a
definition, XML tag, note(s), example list of values and format are provided. The format column may
include the number of characters for the associated data element, where "A" specifies alphanumeric,
"N" designates numeric, and "G" and "D" are used for grouping and date/time respectively.

c.	Data Element Numbering: For purposes of clarity and to enhance understanding of data standard hierarchy

and relationships, each data group is numerically classified from the primary to the data element level.

d.	Code and Identifier Metadata: Metadata, defined here as data about data or data elements, includes their
descriptions and/or any needed context setting information required to identify the origin, conditions of
use, interpretation, or understanding the information being exchanged or transferred. (Adapted from
ISO/IEC 2382-17:1999 Information Technology Vocabulary—Part 17: Databases 17.06.05 metadata).
Based on the business need, additional metadata may be required to sufficiently describe an identifier or a
code. A note regarding this additional metadata is included in the notes column for identifier and code
elements. Additional metadata for identifiers may include:

•	Identifier Context, which identifies the source or data system that created or defined the

identifier

Additional metadata for codes may include:

•	Code List Identifier, which is a standardized reference to the context or source of the set of

codes

•	Code List Version Identifier, which identifies the particular version of the set of codes.

•	Code List Version Agency Identifier, which identifies the agency responsible for maintaining the set

of codes

• Code List Name, which describes the corresponding name for which the code represents
e. Appendix A, lists the references for Lat/Long Data Standard. Appendices "B" through "I" provide

example lists of values for the designated data elements. The tables present code and name (General
or Specific where applicable) plus value meaning for each listed value.
