Import NASA DEM in GRASS GIS

The NASADEM_HGT dataset is a 1 arcsecond void-filled dataset which combines data from the SRTM and ASTER GDEM data. It can be downloaded from EarthData in 1° by 1° tiles. But if you are using GRASS GIS, downloading is greatly fascilitated using the r.in.nasadem addon. The addon imports all NASADEM tiles covering the current region or region extents given with the region option into GRASS and patches the tiles together.
