This EnviroAtlas web service supports research and online mapping activities related to EnviroAtlas (
). This web service includes the State, County, and Census Block Groups boundaries from the TIGER shapefiles compiled into a single national coverage for each layer. The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB).
In order for others to use the information in the Census MAF/TIGER database in a geographic information system (GIS) or for other geographic applications, the Census Bureau releases to the public extracts of the database in the form of TIGER/Line Shapefiles. The U.S. EPA Agency Central GIS Support team has compiled these shapefiles into a single national file geodatabase to streamline data management and analyses.
