Moin Markus & Markus,<br>
<br>
did you use the NASADEM further than importing it in GRASS?<br>
<br>
<br>
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.<br>
<br>
The import with r.in.nasadem in a WGS84 Location just worked. <br>
Thanks a lot metzm!<br>
<br>
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).<br>
<br>
<br>
Do you have any solutions or hints how to proceed?<br>
<br>
<br>
cheers<br>

<div dir="ltr">Hi all,<br>
<br>
NASA via lpdaac has released a new global DEM with 1 arcsec
spatial resolution:<br>

"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. The improvements
were achieved by reprocessing the original SRTM radar signal
data and telemetry data with updated algorithms and auxiliary
data not available at the time of the original SRTM processing."<br>
<br>
<div>All layers of the NASADEM_HGT.001 product can be imported
into GRASS with the addon r.in.nasadem:</div>
