Online generation of CAD files for Earth terrain geometry

We improve SRTM Digital Elevation files (1 x 1 square degree) by combining them with coast line and ETOPO bathymetry data. An improved HGT file and corresponding STL file can be downloaded.
Specify lower left corner of the area and click [Update]. New file generation and display takes 1-2 minutes. Please wait.
