Constructed using 1 arcsecond resolution SRTM data from the Space Shuttle (about 2.4 million facets). I know it's a big file but, it looks great. It was made 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. I hope to release the new software as soon as I get any kinks out.
