hi @ABraun , many thanks for your kindness response, I have done my research thoroughly and I have used these instructions as well. Now to explain each of their plots I want to know exactly what each of these commands did for me(I mean in more detail.). Tell me what you know. Thank you
'w' for wrapped phase
'w-d' for wrapped phase minus smoothed dem error
'w-o' for wrapped phase minus orbital ramps ('w-dm', 'w-do', 'w-dmo')
'p' for spatially filtered wrapped phase
'u' for unwrapped phase
'u-d' for unwrapped phase minus dem error
'u-m' for unwrapped phase minus and master AOE
'u-o' for unwrapped phase minus orbital ramps
'u-a' for unwrapped phase minus topo-correlated atmosphere
('u-dm', 'u-do', 'u-da', 'u-dmo', 'u-dma', 'u-dms', 'u-dmao', 'u-dmos')
'usb' for unwrapped phase of small baseline ifgs
('usb-d', 'usb-o', 'usb-a' also 'usb-do','usb-da', 'usb-dao')
'rsb' residual between unwrapped phase of sb ifgs and inverted
'd' for spatially correlated DEM error (rad/m)
'm' for AOE phase due to master
'o' for orbital ramps
's' for atmosphere and orbit error (AOE) phase due to slave
'v' mean LOS velocity (MLV) in mm/yr ('v-d', 'v-o', 'v-a', 'v-do,
'v-da', 'v-dao')
'vs' standard deviation of MLV (mm/yr) ('vs-d', 'vs-o', also 'vs-do')
'vdrop' MLV calculated from all but current ifg (mm/yr)
'vdrop-d'
'vdrop-o' (also 'vdrop-do')
oh, thanks. My master path is set incorrectly. It is now resolved.Another problem is that I found in running splitting_ slaves.py, some images are not split, and the folder is empty. Is this caused by no orbit data? Can I set false to true in XML to avoid thisļ¼
Python 2.7. I found that the image that has not been split is indeed because there is no orbit data, including POE and RES. The error message displayed is as follows. But the time is from April to October 2021. In fact, there should be orbit data. I guess itās the bug of SNAP
Somehow, gpt struggles with orbit data while the error from last March was fixed for the gui. You can test with one scene by manually downloading the orbit file and see if the error persists. https://qc.sentinel1.copernicus.eu/
Yes, I solved this problem by manually downloading orbit data. Another small problem is that a target.dim and target.data is finally generated, are these useful and can I delete them?
Thank you. It seems that every time I run gpt, āGDAL not found in systemā¦ā will be displayed. Although there is no impact, is there a way to solve this problem? And will it waste time searching the GDAL directory every time?
You can introduce the border coordinates of a large rectangle that include the entire subswath.
snap2stamps was thought to be used by people with interest in small AOI and limited computer resources, but if this is not your case you can not subsetting by following my advice of above
