[GRASS-user] DEM to DTM

[José Anderson]

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
