Hello, Professor.I have obtained POT data of three strips. I would like to ask you if I have obtained azi_offset.grd corresponding to three sawth, what should I do to make them join together? I tried to use grdsample to make the grd data of F2 F3 strip the same as that of F1 1.gmt grdsample azi_offset2. -Gtemp2. grd -Iazi_offset1.grd 2.gmt grdsample azi_offset3.grd -Gtemp3.grd -Iazi_offset1.grd Then grdpaste grid1. 3.gmt grdpaste temp2. grd temp3.grd azi_offset1.grd -Gmerged.grd was used to concatenate, but I failed. I would like to ask you how to concatenate it image

You may need to use merge_swath to combine them in radar coordinates and then recompute a trans.dat with the new PRM file generated and then use proj_ra2ll.csh to project things back to geo coordinates.
