One of the most interesting NASA projects is the Shuttle Radar Topography Mission. SRTM obtained elevation data at a global scale at an unprecedented resolution. When I learned about it, the first thought that came to my mind was that it would make perfect sense to link elevation data with the database of populated places I built using NIMA and USGS data sources. The task proved very challenging, primarily due to the volume of data involved. The effort was worth it though, because now you can go to the populated places section and find the elevation, in meters and feet, of every single city, town, and village of our planet. Check my hometown, for instance. La Paz is at an altitude of 3782 meters (12408 feet) above sea level.
