[GRASS-user] NASADEM: new global 1 arcsec DEM (Robert Nuske)

Ciao Robert,
if you are looking for DEM’s for Germany, I would also suggest the following:

  1. https://www.eea.europa.eu/data-and-maps/data/copernicus-land-monitoring-service-eu-dem

  2. https://spacedata.copernicus.eu/web/cscda/dataset-details?articleId=394198

Hope this helps,
Conrad

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

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. 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."

All layers of the NASADEM_HGT.001 product can be imported into GRASS

with the addon r.in.nasadem:

https://github.com/OSGeo/grass-addons/tree/master/grass7/raster/r.in.nasadem

Enjoy!
