hi all,
after unwrap the phase i got the unwrap phase image.but for DEM generation when i convert the phase value into height a new height image formed but no height value shown there. so can anybody please tell me how can i get the proper DEM of the selected area from this unwrap image?
What are the steps you followed? in case I could tell you where is the error.
co registration>debrust>insar formation> subset> topographic phase remove> filtering>unwrapping>phase to height conversion
co reg…(the out put should be deramp and dmod)…> s-1 range shift …> s-1 azimuth shift…>deburst…>subset…>infgram formation and continue as you did before.
