Overview

The U.S. Geological Survey (USGS) National Atlas of the United States of America includes four distinct product components: hard copy maps, GIS data sets, geostatistical data sets, and web-based mapping capability. National Atlas GIS data sets are downloadable from the Web in shapefile or SDTS formats and can also be accessed locally on the Libraries GIS Data server. Web-based mapping capability is provided by the USGS.

Data Layers and Access

The following GIS data sets can be found in the National Atlas and are available via the Libraries RPP Novell server. Note that these data layers can also be downloaded directly from USGS:

The Environmental Protection Agency (EPA) created the Envirofacts Warehouse to provide the public with direct access to the wealth of information contained in its databases. The Envirofacts Warehouse allows you to retrieve environmental information from EPA databases on Air, Chemicals, Facility Information, Grants/Funding, Hazardous Waste, Spatial Data, Superfund, Toxic Releases, and Water Permits and Drinking Water. You may retrieve information from several databases at once, or from one database at a time. You may use online queries to retrieve data from these sources and create reports, or you may generate maps of environmental information by selecting from several mapping applications available through EPA's Maps On Demand.
