The institute assists in the availability and technical support of land cover data sets through increasing public and scientific awareness of the importance of land cover science.

National Elevation Dataset (NED) - The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska.

National Atlas - Nationalatlas.gov? contains a remarkable range of products and services to meet the diverse needs of people who are looking for maps and geographic information about America.

National Map Viewer and Download Platform - The National Map Server is the ultimate location to explore and retrieve data. U.S. Geological Survey (USGS) and the EROS Data Center (EDC) are committed to providing access to geospatial data through The National Map. An approach is to provide free downloads of national base layers, as well as other geospatial data layers. These layers are divided into framework categories: Places, Structures, Transportation, Boundaries, Hydrography, Orthoimagery, Land Cover, and Elevation. Along with providing access to the data, the site contains: Tutorial to help with downloads, Information about the downloadable products, Frequently Asked Questions, and Links to product homepages and information pages.
