External DEM for SLC data coregistration

[Arjun]

same issue mentioned here by @qglaude

Use of external DEM not in EPSG:4326

Yep I tried it too. I don’t know if it is because it’s at very low latitudes but the “warp” function does not resample correctly. It does not take into account areas below 70° South Before reprojection : [image] After reprojection to 4326 (and re-reproject on-the-fly in 3031) -> you can observe a small gap in the middle of Antarctica with no value [image]

I processed data Ace30 DEM as Geo-coding and terrain correction and REMA 200m DEM in streographic projection as in subtracting topographic phase removal …and this is the result i got as displacement.
