Dear all, I was using SARscape to process ASAR data these days. After unwrapping the ifg, i tried to geocode it, an error occured like this: ERROR : FILE ERROR [FILE INCONSISTENCY] (E:\ENVISARscape_results\Envi\unwrapped interferogram\unw_ifg_upha) Then i tried the Refinement and Re-flattening step, another error came: ERROR : GENERIC ERROR [] ((null)) Read Phase: SARscapeInSAR_DInSAR ENVI 4.3.000Jan 13 2011 FILE=..\..\..\source\main\main_dem_module\main\main_dem_module.cpp LINE=190 (errno = 0) BTW: it's okay to geocode the wrapped ifg. How to fix it?? HELP~~ Thank u all!!
