I would like to ask if someone had success with using EU DEM as provided by CLMS
link - https://land.copernicus.eu/imagery-in-situ/eu-dem. I downloaded a tile and transformed it
into WGS84, but when I tried it into SNAP as external DEM it resulted in several error messages
such as “Java heap error”. I was challenged to test this since this DEM provides real ASL heights
and the sea has “no data” values.
@ABraun I can’t believe the error is memory related - the PC I use has 48GB RAM
Thank you for the suggestion to check with SNAP - I did it only in QGIS.
What I see you tried with GRD data while my intention is to use the DEM in interferometric processing.
But I will try it anyway.
I noticed that it takes considerably longer when “re-project tie-point grids” is checked. In case of simple DEMs into WGS84 this can be neglected. Doesn’t help regarding this topic, but still wanted to share.
