Error in Terrain correction (PolSARpro 5.0 and 6.0) when using an external DEM

Hello all,

I am trying to Terrain correct a T3 matrix generated from Radarsat 2 data using an external DEM (SRTM 1), but there are two types of error I am getting:

  1. with ASF Map ready (PolSARpro 5.0)- unable to correlate both the images (the DEM and the one to be TC)
  2. with PolSARpro 6.0- it is Geocoding the matrix using the external DEM but the output image is laterally inverted.
    Thanks in adavance
