How does EPA use Geographic Information Systems in its work? Does EPA have GIS data available online?
Much of EPA's geospatial data is available from EPA's National Geospatial Program home page at http://www.epa.gov/geospatial/ . For additional information about EPA’s GIS data, please contact the Geospatial Program: http://www.epa.gov/geospatial/contact.html.
EPA’s Region 7 website provides information about what kind of uses EPA has for geospatial data. Some examples are listed below and more information can be found on the Region 7 website: http://www.epa.gov/region7/government_tribal/gis_info/project.htm. Region 7 also provides additional links to other EPA, Federal and state GIS data sources: http://www.epa.gov/region7/government_tribal/gis_info/link.htm.
EPA is currently using GIS for the following activities:
-Environmental Justice Applications
-Superfund Site Assessment
-Total Maximum Daily Load for streams (TMDL)
-Track pollutant distribution
-Identify threatened/endangered species in watersheds
-R-EMAP: Regional Environmental Monitoring & Assessment Program: Regional scale analyses of water quality and fishery health
The following publicly available EPA databases incorporate GIS data:
Better Assessment Science Integrating Point and Nonpoint Sources (BASINS) (http://water.epa.gov/scitech/datait/models/basins/index.cfm) - Integrates a geographic information system (GIS), national watershed data, and state-of-the-art environmental assessment and modeling tools into one convenient package.
The Envirofacts Database (http://www.epa.gov/enviro/) uses spatial data from a variety of sources, in several different mapping applications to provide information about air, water, waste, toxics, and more. This data can be searched by location.
The Clean Air Markets Division (http://www.epa.gov/airmarkets/maps/who.html) is using geographic data to assess the environmental effectiveness of the Acid Rain Program.
Other GIS Resources
Geodata.gov (http://geo.data.gov/geoportal/catalog/main/home.page) also known as the Geospatial One-Stop, provides access to maps, metadata, articles, and other useful tools. The Communities section facilitates idea sharing, while the Marketplace facilitates collaboration on planned data collection activities.
Federal Geographic Data Committee (FGDC): http://www.fgdc.gov/.
From the site: "The Federal Geographic Data Committee (FGDC) is an interagency committee that promotes the coordinated development, use, sharing, and dissemination of geospatial data on a national basis. This nationwide data publishing effort is known as the National Spatial Data Infrastructure (NSDI). The NSDI is a physical, organizational, and virtual network designed to enable the development and sharing of this nation's digital geographic information resources. FGDC activities are administered through the FGDC Secretariat, hosted by the U.S. Geological Survey."
United States Geological Survey (USGS) Maps and GIS Data: (http://water.usgs.gov/maps.html)
Downloadable GIS data sets on surface and groundwater, water quality, and water use.
Many other federal agencies (NOAA, Dept of Energy, BOEM, Fish and Wildlife Service, etc.) provide access to GIS data on their websites. Additionally, many state and local governments have their own GIS data that can be accessed online.
