Moin Markus & Markus, did you use the NASADEM further than importing it in GRASS?
I need a DEM for Germany + 10km Buffer. So, I thought NASADEM would be a natural fit and am now trying to get a handle on this dataset. The import with r.in.nasadem in a WGS84 Location just worked. Thanks a lot metzm! The NASADEM documentation states, that the height of the merged DEM (NASADEM_HGT) is above EGM96 geoid and not WGS84 ellipsoid. I have no clue how to get from there to UTM32 with a height reference comman in Germany (DHHN92). Do you have any solutions or hints how to proceed? cheers robert Am 18.02.20 um 22:36 schrieb Markus Metz: > Hi all, > > NASA via lpdaac has released a new global DEM with 1 arcsec spatial > resolution: > https://lpdaac.usgs.gov/news/release-nasadem-data-products/ > > "NASADEM extends the legacy of the Shuttle Radar Topography Mission > (SRTM) by improving the digital elevation model (DEM) height accuracy > and data coverage as well as providing additional SRTM radar-related > data products.
