I have problem when I process ALOS PALSAR SLC Level1.1. My data got from ESA website. with 2. gigabyte. the problem is I can’t processed my data with same the tutorials parameters available in ESA STEP tutorials pdfs titled (ALOS PALSAR Orthorectification Tutorial) especially in that terrain correction ((SAR Simulation Terrain Correction)) in GCP selection Coarse Registration Window Width/Height the 1024, and RMS Threshold 0.5. Some times the notepad residual GCP results in the end of process with no image in color manipulation window . The another Terrain Correction method (RD Terrain Correction) has been done without problems.
The question is how it these parameters effect on the quality and quantity of images where I’m adopted method for detection the archaeological remains (surface and subsurface).
Note: I’m following the workflow
2- Deskewing before multilooking based on the advice of Mr. @lveci in the one of the posts in forum.
4- Speckle filtering (Refined Lee)
5- SAR Simulation Terrain Correction with same parameters mentioned in Tutorial above)
I waiting for any Advice.
