Constructed using 1 arcsecond resolution SRTM data from the Space Shuttle (about 1.6 million polygons). This is using a new and, as yet, unreleased version of SRTM2STL. The source code for creating files at 3 arcsecond resolution is available up on github under the GNU license. Go to github and search for SRTM2STL.
