NoData on ocean pixels with Copernicus 30m Global DEM

[alexisahedo]

Hello dear @johntruckenbrodt

First, I’ll like to thank and congratulate you for this excellent work, it has been really useful in my current project.

I’m facing a problem and would like to ask for your advice, one of the areas of interest I’m working on is a costal zone, when I use geocode on the selected scene with Copernicus 30m Global DEM all the ocean and marsh pixels are classified as noData, I’m guessing that the reason is because the DEM use 0 as ocean’s value which causes that ocean’s pixels to be classified as noData value. To try to solve the problem, I’ll like to change the noData value written to my rasters to “nodata” or something like that to avoid such issue. Is it possible to accomplish it with pyroSAR?

I know this problem could be potentially solved using SRTM 1sec HGT, but I’m trying to follow the Digital Earth Africa recommendations (basically Sentinel-Hub product) and they used Copernicus DEM. I would really appreciate if you could help me.
