FAQ
HGT to OBJ Conversion
What are HGT files?
HGT (short for height) is the file extension of elevation data from the Shuttle Radar Topography Mission (SRTM), a NASA mission of 2000 that mapped the terrain of most of the world, from about 56 degrees south to 60 degrees north. The data are cut into tiles, each covering exactly one degree of latitude and one degree of longitude, and every tile is a separate file. The name tells where it belongs: for example, N20E100.hgt covers the area from 20 to 21 degrees north and from 100 to 101 degrees east. The file itself contains only the heights in meters, with no other information. The data come at two levels of detail, about 90 meters per cell and about 30 meters per cell, and they are in the public domain.
What are OBJ files?
OBJ is a 3D model format created by Wavefront Technologies for its Advanced Visualizer software and now supported by almost every 3D application, which makes it one of the most common formats for exchanging models. A file of this type is plain text that describes the shape of an object: the coordinates of its vertices, the texture coordinates used for UV mapping, the surface normals, and the faces that join them into polygons. Named groups divide a model into separate parts. Colors and materials are not stored in the file itself but in a separate .mtl file that it refers to, with the texture images kept alongside. The format holds a static model only, with no animation, bones, or lights.
