pyTerra

pyTerra is a Python module that allows you to make requests to Microsoft’s TerraServer (http://msrmaps.com/). With it, you can download (older) cartographic images for any almost any geographic extent in the US.

The TerraServer has almost complete coverage of the United States for two very important cartographic products, topographic maps and digital orthographic photos (sometimes called DOQs or DOQQs). You can find out more about DOQs here (http://mapping.usgs.gov/www/ndop/) and more about what topographic maps are here (http://mac.usgs.gov/mac/isb/pubs/booklets/symbols/). The TerraServer hasn’t been updated in a number of years, and there are now many other imagery sources available, but the TerraServer was on of the first with nation-wide coverage.
