Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software.
NOAA DigitalCoast Directs NOAA to establish and implement the Digital Coast to: (1) collect data concerning coastal elevations, land use and cover, habitat and submerged aquatic vegetation, parcels, planimetrics, socioeconomics, and human use; and (2) integrate other data sources for the broadest measure of coastal resource management constituents and applications.
The National Map The geographic information available from The National Map includes orthoimagery (aerial photographs), elevation, geographic names, hydrography, boundaries, transportation, structures, and land cover.
TopoView - United States Geological Survey (USGS)
TopoView highlights one of the USGS's most important and useful products, the topographic map. Purpose is to provide a digital repository of USGS 1:250,000 scale and larger (more detailed) maps printed between 1884 (the inception of the topographic mapping program), and 2006. All of the topo maps can be downloaded in multiple formats, JPEG, Geo-PDF, Geo-TIFF, KMZ.
