Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information.

This is a collection of 1,612 Soil Survey Maps produced from 1899 to 1950 by the U.S Department of Agriculture. The vast majority of the maps are at a scale of one inch equals one mile (1:63,360). While the methodology for classification of the soils is obsolete, these maps are rich in cultural detail. The maps are provided courtesy of the Geological Survey of Alabama and Amelia Gayle Gorgas Library.

The Geospatial Data Gateway (GDG) provides access to a map library of over 100 high resolution vector and raster layers in the Geospatial Data Warehouse. It is the One Stop Source for environmental and natural resources data, at any time, from anywhere, to anyone. It allows you to choose your area of interest, browse and select data, customize the format, then review and download.

The USGS Volcano Hazards Program enhances public safety and minimize social and economic disruption from volcanic unrest and eruption. We accomplish this by delivering effective forecasts, warnings, and information about volcano hazards based on scientific understanding of volcanic processes.
