About EnviroAtlas

EnviroAtlas is a collection of tools and resources to provide data, research, and analysis on the
relationships between nature, people, health, and the economy.

EnviroAtlas is designed for use by government, professional, academic, and community users as well as
members of the public with an interest in ecosystem services, clean air, water resources, hazard
mitigation, recreation, wildlife, conservation, climate, transportation, land use, health, and sustainable
and healthy communities.

The EnviroAtlas interactive map displays spatial data layers grouped by category at the national level and
for select communities. These data layers depict environmental metrics calculated or modeled by EPA and
its partners, and may be referred to as "metrics" or "layers" in EnviroAtlas documentation. Map layer
exploration is facilitated by the navigation toolbar (for zooming in and out, panning, and re-centering the
map), bookmarks to commonly used locations, feature identification, and a locator (overview) map.

For additional information about EnviroAtlas, please see the EnviroAtlas home page.

Interactive Map Disclaimer

The EnviroAtlas interactive map initially opens with an EnviroAtlas use disclaimer. After several seconds
the disclaimer pop-up window provides a button to agree to the terms and conditions of the disclaimer.
This disclaimer pop-up contains two tabs: the Main tab with the user agreement, and the Demo Video
tab which contains a link to the "Welcome to EnviroAtlas" video, explained below. After reading the terms
and conditions for use on the Main tab, select the Agree button to proceed to the map. If desired, check
the Don't show again box to bypass the disclaimer pop-up on subsequent visits to EnviroAtlas (bypass

Interactive Map Start Location

Once the disclaimer is accepted, the interactive map offers
dropdown menus to select a starting location for the map.
Select a state from the State (Required) dropdown (currently
only the 48 contiguous states are available in the list) and,
optionally, a county within the selected state. If no county is
selected, the state boundary is used for the starting location.

When the selection box is empty, typing in the first letter of a
state (or county for the optional county menu) scrolls in the list
to that letter. For example, typing "i" in the blank State
(Required) selection box moves the scroll list to "Idaho" - the
first state in the list starting with "i". Once a state is selected,
the county list is populated and one county may then be
selected. Once the state or state and county have been
selected, click the Go to my start location! button. The
Interactive Map zooms to the selected location.

The map automatically displays state and county boundary lines
for reference. To turn off these layers, click on Supplemental
Maps in the ribbon above the map to access the Supplemental
Maps table of contents, and uncheck the layers in the
Boundaries category.

Ecosystem Services and Biodiversity

Layers

The Ecosystem Services and Biodiversity link provides layer choices
developed for the National and selected Community geographic extents.

After selecting the geographic extent of interest, the TOC pop-up will appear
with layer choices.

The geographic extent of the National layers includes the conterminous 48 United States. EPA and
EnviroAtlas partners have developed these layers to help governments, researchers, and other interested
parties understand the status and impacts of Ecosystem
Services within a watershed or region. As shown earlier,

National layers are arranged in seven categories:

1.	Clean Air

2.	Clean and Plentiful Water

3.	Natural Hazard Mitigation

4.	Climate Stabilization

5.	Recreation, Culture, and Aesthetics

6.	Food, Fuel, and Materials

7.	Biodiversity Conservation

Most of the National layers available in the interactive map
through the Ecosystem Services and Biodiversity link are
summarized by 12-digit hydrological unit code (HUC).

Community

Community layers are continually being created. Layers are
arranged by community, and are organized in the same
categories as the National layers. The Community layers are
designed to be used in conjunction with the national-scale
layers. Each community includes layers that have been
summarized by US Census Bureau block group. The defined
boundaries for the community are based on selected block
groups within the 2010 US Census Bureau Urban Area
boundary for the community.

People and Built Spaces Layers
The People and Built Spaces link contains layers associated
with demographics and built environments. Demographic
layers make up the majority of these datasets. They are
displayed as National census tract level polygon data and
Community census block group point (centroid) data.

The National American Community Survey (ACS) category
includes layers with information about population (race,
poverty, age, and education) and housing units for the
entire US by census tract from 2010.

The Community layers display information about
populations vulnerable to detrimental impacts to the
environment due to age or economic disadvantage. Also,
information relating to schools and day care facilities are included

Supplemental Maps Layers
The Supplemental Maps link contains layers that provide
context and additional information for exploring
Ecosystem Services along with natural and human-altered
landscape features. Supplemental Maps layers are
divided into:

1.	Boundaries

2.	Biophysical Data -Vector

3.	Biophysical Data - Raster

4.	EPA WATERS Data

A variety of layers including rivers, wetlands, political and
other boundaries, USGS Gap Analysis Program (GAP)
data, EPA Ecoregions, high-resolution land cover data for
communities, impaired stream reaches, etc. are included under Supplemental Maps. Unlike most other
layers, these layers are mapped with unique boundaries and may not be organized by MUC or Census
Bureau boundaries. More information about each layer may be accessed by clicking the blue circular "i"
icon and selecting the Data Fact Sheet link.

Layer Functionality

The EnviroAtlas interactive map includes a variety of functions which act upon the map layers. These
functions range from simple tasks such as turning layers on and off, to more complex functions such as
modifying the appearance of a layer in the map (also called "change symbology"). In addition, detailed
information about the contents of individual layers may be obtained. Much of this functionality is
accessible through the TOC.

How to Interact With Map Table of Contents (TOC)

Within each TOC pop-up, layers are arranged by category. For example, the Ecosystem Services and
Biodiversity - National layers are arranged in seven categories:

1.	Clean Air

2.	Clean and Plentiful Water

3.	Natural Hazard Mitigation

4.	Climate Stabilization

5.	Recreation, Culture, and Aesthetics

6.	Food, Fuel, and Materials

7.	Biodiversity Conservation

Users may interact with the named items in
each TOC via the plus/minus sign, the
checkbox, and the blue circular "i" icon.

Plus Sign

The plus sign ("+") indicates that individual layers are
collapsed into the category to save space in the TOC and
to provide thematic grouping. Many of the categories
contain additional levels of subcategories which further
refine the layer(s) within the overall category. Once
clicked, the plus sign becomes a minus sign and
reveals the subcategory or theme names or individual
layers in the category. To view the available layer
names, click the plus signs to expand the TOC. The
example at the right shows that the Climate
Stabilization category is comprised of three
subcategories (Land Cover, Ambient Temperature, and
Greenhouse Gasses and Pollutants), the Land Cover
subcategory contains two additional subcategories
(Vegetated and Developed), and the Developed
subcategory contains three EnviroAtlas layers.

Classification - provides three classification methods:
o Natural Breaks (Jenks method) - classes are
based on natural groupings in the data,
maximizing differences between classes,
o Quantile - classes are created by assigning an
equal number of features per class. The default
EnviroAtlas layer classification in the TOC uses
five-class quantile (or quintile) classification,
o Equal Interval - classes are split into equal value
ranges based on the minimum and maximum
values.

Number of classes - provides the number of classes
in the classification, with a minimum of four and a
maximum of 12.

Higher values - the color assignment of the highest
values in the classification.

•	Lower values - the color assignment of the lowest values in the classification. Each class between
the highest and lowest values is assigned an intermediate color between the two.

•	Transparency - assigns a transparency of the layer from 0.00 (completely transparent) to 1.00
(completely opaque).

•	Clear this layer - button turns the layer off and closes the Change Symbology pop-up window.

•	FOR COMMUNITY LAYERS ONLY: Classify all

classifies the values across all communities in the
TOC rather than just the selected community. Once
the Classify all communities button is clicked, the
button toggles to Classify selected community,
which returns the map to the originally selected
layer and symbology. The graphic (right) shows
Durham, NC as the selected community while the
classification is displaying data for all communities.

When classifying all communities, an option to click
on the Find communities button is provided. This
button opens the Bookmarks window. Click on the
desired community in the Bookmarks tool
(described in the Mapping Toois section). Once a
community is selected, the map will pan and zoom
to the selected community.

Identify Tool

Identifying values for features displayed on the map is available
for select map layers. When a layer in either the Ecosystem
Services and Biodiversity TOC (both National and Community) or
People and Built Spaces (Community layers only) TOC is selected
for display, left-clicking on a mapped feature highlights the
feature (HIJC or census block group) and invokes a new pop-up
showing the layer's data value for the feature.

When more than one layer is displayed, multiple features may be
selected when a map location is interactively queried. Data values
for each feature in each layer are populated in the pop-up and may
be viewed by clicking on the forward and backward arrows in the
top bar. The text between the arrows indicates how many "pages" of values are visible. Dismiss the pop-
up for all pages by clicking the "X" in the upper right corner.

NOTE: The Identify pop-up limits the number of digits after the decimal place to two. For some layers,
this limitation may result in data values appearing incomplete. For these layers, the range of values can
be obtained by looking at the map legend classification for the layer in the TOC.

Example of identify pop-up pages for
two displayed layers.

Map Navigation and Display Tools

EnviroAtlas provides multiple methods to navigate within the map, modify the display, and obtain map
extent and coordinate information.

Clear Layers

Clear Layers on the menu bar removes all layers from the Interactive Map - including any open tool.
Clicking Clear Layers refreshes the map without reloading layers or adjusting the map extent. This function
is useful when a clean start with the map layers is desired without restarting the Interactive Map page.

Data Layer Matrix

The Data Layer Matrix item on the menu bar opens a new browser tab containing a table (PDF format)
listing all EnviroAtlas Ecosystem Services and Biodiversity layers and the categories in which the layers
reside. A link to the associated metadata is also provided in the table. This same table is accessible through
the EnviroAtlas Data website as a PDF, text file, or MS Excel® xls spreadsheet.

Help Document

Clicking Help in the menu bar opens this help document - "EnviroAtlas Interactive Map User's Guide."

Analysis Tools

The Analysis Tools link provides three tools to assist in exploring and
analyzing the data:

1.	Analyze Ecosystem Services

2.	Raindrop Tool

3.	Elevation Data

NOTE: Some of these tools are still under development and are for
demonstration purposes only. The tools and data are provided as an
example of the tool functionality.

Analyze Ecosystem Services Tool

Analyze Ecosystem Services is an interactive mapping tool that displays index values for the seven
ecosystem services within a selected 12-digit HUC. The index values for each ecosystem service, which
range from 0 to 1.5, represent the degree to which certain ecosystem attributes within the HUC, when
analyzed together, are able to mitigate stressors and maximize human health benefits. Separate index
values are displayed for each ecosystem services category in graphical and tabular formats.

Multiple HUCs may be displayed simultaneously to facilitate comparison. Select another location on the
map to display another HUC. The radar graph for the each newly-selected HUC is superimposed on the
previous graph. In the example above for HUC 102100030306 and 102100030401, the index value is
lowest for the Food, Fuel, and Materials and the Clean and Plentiful Water ecosystem services categories.
This indicates that ecosystem attributes which are known to provide human benefits in the Food, Fuel,
and Materials and Clean and Plentiful Water categories are lacking. The highest index value is in the Clean
Air ecosystem services category which indicates that ecosystem attributes in these HUCs offer
comparatively better human benefits in that category. In this example, HUC 102100050101 is comprised
of ecosystem attributes showing a higher index value for the Natural Hazard Mitigation ecosystem
services category.

The settings icon ( ) has three tabs of information:

•	Map - clicking on the checkbox
allows the map to automatically pan
and zoom to the selected HUC.

•	Field Assignment - by placing values
from 0 to 1 in a variable column and
the associated Ecosystem service
category row, the selected HUC will
display the graph using the fields
assigned.

•	Field Normalization - by modifying
the minimum and maximum values
of the variable, the field
normalization in conjunction with
the field assignment create a
weighting used to populate the graph for each HUC selected after the changes are made. For
information about the calculations, please contact the EnviroAtlas team.

Only 12 distinctly colored HUCs are able to be displayed on the map simultaneously, however, the graphs
can display additional HUCs. As HUCs are added to the map and graphs, the ability to discern them may
become difficult. Graphs for any of the HUCs may be turned off by clicking the HUC number in the widget's
legend.

Raindrop Tool

The Raindrop Tool generates a raindrop flow path (linear
feature) based on the interactive selection of a location and
returns the distance to the nearest water feature as
depicted in National Hydrography Dataset Plus (NHDPIus).

The tool pop-up window includes three icons at the top:

Results ( ), Settings ( ), and Help ( ).

NOTE: It may be helpful to display the NHD Flowlines layer
while using this tool to provide context The NHD Flowlines
layer is in the Supplemental Maps link, within the
Biophysical Data - Vector category. This tool is built using
nationally available 30 meter elevation data; it does not account for buildings or engineered
stormwater infrastructure (such as culverts and pipes) and is not for use in heavily engineered locations.

Draw and Measure

The Draw and Measure tools allow points, lines,
polygons, and text to be placed on the map.
Measurement values (if activated) for the features
drawn can also be displayed: lengths for lines, and areas
and perimeters for polygons. To discover the function
of each feature creation tool, hover the mouse over a
tool to see a pop-up describing the tool.

To add a feature, click on the desired feature creation
tool. When the feature creation tool is selected, its icon
displays with a blue highlight. Before creating a new
feature, the feature properties can be customized for
the feature being created. Note that line and polygon
features also support measurement values, which must
be activated by checking the Show Measurements
check box.

To add a new line or polygon feature, click the map at
the desired location and define the feature extent, then
double-click to finish the feature. To add a point
feature, click the map at the desired location.

In the case of the text tool, the text string needs to be
specified in the Text input box first, then click the map
to place the text. Note: For measurements to display for
a feature, the feature must be activated and units must
be set before a feature is created to display on the map.

Click Clear drawings to remove added features or text.

Created features and text are temporary and only
visible when the Draw tools are active or minimized.
The drawings are located on a graphics layer which is
automatically instantiated when the widget is opened
for the first time. These features are removed from the
map display when the Draw and Measure tools are
closed. Features and text will reappear when the Draw
and Measure tools are reactivated.

Map Legend

The Map Legend tool provides a dynamic legend that automatically updates if the visibility of a layer or
sublayer changes. The order in which layers appear in the Legend corresponds to the layer order in the
TOC. Note: Basemaps are not shown in the Legend. This Map Legend will display with selected layers in
the TOCs and is provided here for convenience if the widget is closed or removed from the display. Change
Symbology creates a separate legend within the tool.

Print

The Print tool provides a simple map printing function. Options include the ability to add a title and, if
desired, a subtitle to the map. Note: For best results, set the layout for the map to Landscape.

Add Shapefile to Map

The Add Shapefile to Map tool allows the uploading of a GIS shapefile dataset into the EnviroAtlas
interactive map. Symbols and labels for the shapefile features are configurable in the toot

The following preliminary steps must be taken before the shapefile is loaded:

1.	Review the shapefile to ensure that the .shp and .dbf component files are present.

2.	Verify the shapefile projection is defined.

•	If the projection is undefined, a projection must be accurately defined so EnviroAtlas can
reproject into the native map projection (Web Mercator Auxiliary Sphere, WGS 1984, units
in meters).

•	A shapefile with a defined projection will include a .prj component file. While not essential
to loading a shapefile in EnviroAtlas, the .prj component file is highly recommended to avoid
unexpected results.

3.	Compress (zip) the shapefile component files (including the .shp, .dbf, .prj and any other
component files as well) using a file compression application that results in a .zip file output. The
zip file should contain only one shapefile and must contain one .shp file and one .dbf file.

To load the zipped shapefile into EnviroAtlas, click Add Shapefile to Map.

The Add Shapefile to Map pop-up appears.
The two icons at the top of the pop-up provide
options for adding the shapefile. The Load
Shapefile icon ( ) provides guidance on
loading a shapefile into EnviroAtlas, along
with the button to Load Local Zipped
Shapefile. The Preferences icon ( )
provides options for shapefile feature labels
and symbology.

The guidance text on the Load Shapefile
screen provides four pieces of helpful

Add Shapefile to Map	Jpl	_ ©

| To add your shapefile to EnviroAtlas. the files must Be zipped.

Yourzipped shapefile must contain a .shp file and a .dbf file. It can
also contain an optional prj file.

While loading complex or large line or polygon shapefiles is
possible, performance of the application will be impacted by these
uploaded shapefiles.

Before uploading each shapefile zip, modify the symbology in the
preferences for the point, line, or polygon layer being added to
EnviroAtlas using the wrench icon button above. These uploaded
shapefiles will remain on the map until removed through the Add
Shapefile widget or until the Interactive Map window is closed.

information about preparing a shapefile for loading. Details about the zip format and the shapefile
component files are addressed at the beginning of this section.

Many simple shapefiles load easily into the EnviroAtlas map. However, shapefiles with complex line or
polygon geometry or with a large number of features may be problematic and take an excessive amount
of time to load. EnviroAtlas may return an error during the loading process, or performance may slow
after loading a large or complex shapefile. If this is the case, consider removing the shapefile from the
EnviroAtlas map and editing the shapefile using GIS software to simplify the polygons or lines and/or
removing records that are unnecessary for visualization. Once edited, ZIP the shapefile and reload.

Symbology can be modified before loading
the shapefile (via the Preferences button) or
after loading the shapefile (via the Configure
this Shapefile button).

To modify the symbology before loading the
shapefile, click the Preferences icon ( ).
The pop-up shows options for labels and
symbology. The symbology options are
divided into the three shapefile geometry
types: Point, Line, and Polygon. Set the
desired label configuration preferences, and
set symbology configuration preferences for
the geometry type that matches the
shapefile being loaded.

NOTE: All features in the shapefile are
represented with a single symbol. Classifying
symbols by type and using varied symbology
is not available.

Import Excel/CSV Lat/Long File

The Import Excel/CSV Lat/Long File tooi allows for the loading of a Microsoft Excel® (MS Excel®)
spreadsheet file or comma-separated values (CSV) file into the EnviroAtlas interactive map to display point
locations.

The following preliminary steps must be taken before a MS Excel® file or CSV is loaded:

1.	Review the file to ensure that coordinates exist, The coordinates may be either latitude/longitude
(expressed in decimal degrees) or Web Mercator coordinates.

2.	The MS Excel® file must be in 97-2003 format and the file name must have an ".xls" extension.
MS Excel® files with the newer ".xlsx" extension are not compatible. To save a ".xlsx" file as a
".xls", open the file in MS Excel® and perform a Save As to the "Excel 97-2003 Workbook" format.

To load the MS Excel® file or CSV into EnviroAtlas, click Import Excel/CSV Lat/Long File. The Import
Excel/CSV Lat/Long File pop-up appears. Three icons at the top of the pop-up provide options for the
loaded file:

•	The Search icon ( ) opens the Load File (main) page.

•	The Preferences icon ( ) provides options for point symbology.

•	The Results icon ( ) provides a summary of the MS Excel®/CSV file importing and includes the
number of features added to the new layer, a transparency control for the new layer, and the
ability to remove the new layer by clicking on the red 'x' or Clear All Layers.

Once an MS Excel® or CSV file is loaded, the following settings must be set:

•	The appropriate Coordinate System for the new
layer must be assigned by choosing
"Geographies" or "MGRS".	Because
"Geographies" is the more common coordinate
system, it is assumed that "Geographies" will be
chosen for the rest of this guidance.

•	Choose the Projection of the data on file:

Lat/Long, US Albers, or Web Mercator. If the
projection of the data is unknown, try choosing
Lat/Long first. If the layer is created, but a
basemap does not load and the map shows "Map
data not yet available", the projection of the data
is most likely incorrect.

Add Map Service

The Add Map Service tool allows ArcGIS dynamic map services, image services, feature services, tiled
services along with Open Source WMS and KML services to
be added to the EnviroAtlas interactive map.

To add a map service into EnviroAtlas, click Add Map Service.

The pop-up will display the Help text. Click on the Add Map

t'p

Layers tool ( ) to open the add map service window.

Select the appropriate type of map service that is being
added to the map, i.e. ArcGIS Server Dynamic Web Service,

KML Layer Service, or WMS Layer Service (Note: WMS
services will not overlay well if the service does not have a
Mercator projection). Add an optional Layer label for the
map service. This label will display in the Legend. If a Layer
label is left blank, a default name will display in the Legend.

Next, add the map service URL in the "Layer URL (Ending in
/Mapserver)" textbox. For ArcGIS services, the URL should
end with the text "/Mapserver", i.e.
http://gispub.epa.gov/arcgis/rest/services/AgSTAR/EPA AgSTAR AD Proiects/MapServer. Click on the
Add Layer button to add the map service to the EnviroAtlas map.

After the map service is added, the Add Map Service pop-up will automatically display the legend for the
newly-added map service layers (Note: the added map service legends come directly from the services
and cannot be modified). The legend can also be accessed by clicking on the Visibility Settings and Legend

a -

Id	

for Added Layers icon ( ). The visibility of the layers can be set by clicking the check boxes on and off
next to the layer name.

Clicking on the small down arrow to the right of the
map service (Layer label) in the Legend opens a menu
with the ability to set map service transparency, move
map services up and down, and access the REST
endpoint of an ArcGIS map service (KML and WMS may
not have this functionality enabled).

Transparency is only available at the map service level,
not for the individual map layers if there are multiple map layers in a particular map service. To modify
the transparency, click on the drop-down arrow to the right of the service name and select Transparency.
Move the slider bar to the preferred transparency level. When finished, click on the drop-down arrow
again to close the pop-up window.

EnviroAtlas Interactive Map User's Guide

If more than one map service is added to the EnviroAtlas map, the order in which the map services display
can be modified by selecting Move up or Move down. If only one map service has been added to the map,
the Move up or Move down options will not be available.

To access the REST endpoint of the added ArcGIS map service, select Access Web Service. The REST
endpoint will display in a new tab in the browser window.

To remove the added map services, select the Add Map Layers tool ( w ) and click on the Clear Layers
button. Closing or minimizing the Add Map Service window will not remove the added layers and services.
If the window was closed, open the window again and Clear Layers button to remove only the added map
services. The Clear Layers on the menu bar will remove all layers from the Interactive Map.
