The GeoCommunity was also selected by the US Fish and Wildlife service as a distributor of their National Wetlands Inventory (NWI) data sets. This data is available for free download (Click the "Download Data" link above) and is available on CD-ROM
USGS DEMs - The GeoCommunity was selected by the USGS as the first official distributor of SDTS format DEMs. This data is not available for download from the USGS any longer..
Digital elevation model (DEM) data consist of a sampled array of regularly spaced elevation values referenced horizontally either to a Universal Transverse Mercator (UTM) projection or to a geographic coordinate system. The grid cells are spaced at regular intervals along south to north profiles that are ordered from west to east. This data is available for free download (Click the "Download Data" link above) and CD-ROM Click here!
