Topic: error during GCPs optimization step
I have ASTER data and DEM too. I have selected 7 tie points using image-to-image tool in cosi-corr. then I have converted those tie pts into GCPs using "Tie points to GCPs"function. Here I have not provided DEM and Offset coz they are optional. Then to refine the GCPs, I performed GCPs optimization. However during this step I am getting the following error:
SAT_GCPS_OPTIMIZATION:SAT_GCPS_OPTIMIZATION_CORE: Attempt to subscript <PtrHeapVar1796> with X_PIXEL is out of range.
Info: 1) Reference image is in UTM projection, DEM is in Geographic Lat/Long (Both have datum as WGS 84).
2) DEM is not one that was used to orthorectify reference image.
Kindly guide me in this regard.
