[Help]: Merging two different frames #862

Open AmiraZakii opened 10 months ago

AmiraZakii commented 10 months ago

Hello, Please I want to ask about the best way to merge the LOS velocity of three different sentinel-1 frames (they have overlapped areas) after generating by using GMTSAR even in radar or geographic coordinates. Thanks

You could use organize_files_tops[_linux].csh / create_frame_tops.csh / assemble_tops to create a new user-defined frame for TOPS data.

If you mean some older satellites, e.g., ALOS, ERS, ENVISAT, then you need some dark magic (shell scripting) to do so.

@Xiaohua-Eric-Xu, thanks, but do you mean merge all sentinel-1 images before generating interferograms?! as I know organize_files_tops[_linux].csh organize the images?

Yes, see section 3 in the attached document, which sort of describes how to reassemble the data. https://topex.ucsd.edu/gmtsar/tar/sentinel_time_series_5.pdf
