My first experience with using (ASTER) GDEM:
It is an excellent product (better than SRTM DEM) and easy to obtain
0%
It is an excellent product but difficult to obtain
0%
Positional accuracy is satisfactory, but resolution needs to be degraded
18%
Neither positional accuracy nor geomorphologic plausibility are satisfactory
27%
SRTM DEM is still more usefull
55%
