Dear all, I'm in need to start a study in a urban area in which the DTM ( https://en.wikipedia.org/wiki/Digital_elevation_model) is to be obtained from a DEM (SRTM or ASTER).
I've seen GRASS7 can provide DTM from LiDAR maps, but I'm afraid it won't work in this case. So, how to derive a DTM from DEM in GRASS 7? Any answer would be appreciated. Jose
