Radiometric Terrain Flattering

Hi @ABraun,

I able to successfully execute Radiometric Terrain Flattening operation on my data but the output is really strange as shown below:

I couldn’t understand where is the problem. I performed Terrain Flattening with SRTM 1sec, SRTM 3 sec and external TanDEM-X 12m DEM (in WGS84) but getting same outcome. Kindly guide me where is the problem.

I have no idea. Can you please share which dataset you used? I’ll try to reproduce the error.

Hi @ABraun I sent you my data in private massage.

I have received the data and can confirm the errors. I first thought the SRTM would have errors in this region but it looks totally fine. Sigma0 and Beta0 also have reasonable values. Can’t think of a reason why this happens, sorry!
