Geographical Information Systems (GIS) are an old interest of mine. They were used in the enterprise a number of times. Integrity Logic provides a nice view of a public data source that could have lots of creative applications in a GIS. Also a nice example of terrestrial value of space agency data:

Ten years ago, in February 2000, NASA mapped the entire world in eleven days. ... the mission was called the Shuttle Radar Topography Mission (SRTM), and over the course of eleven days, it used a big radar attached to space shuttle Endeavour to get elevation data from the vast majority of solid Earth; practically all land between 60 degrees North and 56 degrees South was included, with a resolution of 30 meters (90 feet). Over 9 terabytes of data were captured. It then took two years to process that data and make it usable (and it’s still being refined to this day) ... '
