I have a couple of TSX interferograms that I got from a data provider as already processed interferograms such as the one below.
The interferograms are in GEOTIFF format and have data values ranging from 0 to 15. I am interested in testing phase unwrapping using Snaphu.
This is why in SNAP I tried to use the Snaphu Export option for just one interferogram in SNAP, but get the message that I need a co-registered stack for this. I therefore tried stacking my interferograms using the Create Stack tool, but am stuck with the following error: Orbit offset method is not support for this product: Ellipsoid.ell2xzy: input values for phi/lambda have to be in radians!
Can anyone help me with this how I could get the export to Snaphu to work?
