Sentinel 1 data : terrain correction

[s.savastano]

Dear @soutmani
I think to have found a reason for that in another post.

Differences in SRTM data

No problem at all @jun_lu. your explanation is perfect and thanks to you again for your support. I appreciate that a lot! For @mengdahl: Marcus you were right, I forgot to consider the latitude in negative being in W and so recalculating the geoid for that pixel belonging to the sea, we have [image] exactly the value 55m more or less. Thank you again to all of you! S Savastano

I hope it helps to answer your question.

Thank you. This makes sense. Now, what can I do if I want my final dem from insar (“elevation_VV”) to be in absolute height? I need this dem later for another application and I want a geoid referenced dem, where the sea is 0.
