The Shuttle Radar Topography Mission (SRTM) is a joint project between the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA).  Data was collected using radar by the Space Shuttle Endeavour during February of 2000.  Elevation data at a resolution of 3 arc seconds is available for areas between 56 degrees south and 60 degrees north latitude. This area includes most of Canada, all of U.S.A., Mexico, Caribbean area islands, Central America, South America and everything in the Eastern Hemisphere, including Australia, Japan, China, South Korea, Philippines, India, the "Middle East", all of Africa and all of Europe (including England, Ireland, Scotland, Spain, Italy and France.) The data covers Russia to 60 degrees north latitude. (Norway, Finland and Sweden are mostly above 60 degrees North Latitude.)

 Terrain for these locations can be broken out of the full data set for those interested in a given area or continent.

The data is a "real world" interferometric scan, so it also includes buildings that may appear along with the topography.
