Hello all, I have just finished processing SBAS using GMTSAR + StaMPS and I get this very strange result:
ps_plot(‘u’) shows the same problem:
Does anyone recognize this anomaly?
Using the following params in Stamps with amplitude dispersion index of 0.6:
lonlat_offset: [0 0]
ref_centre_lonlat: [0 0]
ref_lat: [-Inf Inf]
ref_lon: [-Inf Inf]
shade_rel_angle: [90 45]
Have you already found the problem? Yes, it’s a kinda strange result for unwrapped. Can you do ps_plot(‘w’) and ps_plot(‘usb’)? Do they also look strange?
You might also check the amplitude difference dispersion (ADD) from scatter_SB.ps inside the raw folder.
Sorry for out of topic. Do you have any documents to do the GMTSAR+STAMPS?
No, but if you have any problems I would check on the
Unfortunately I moved on to another orbit as I couldn’t trust these results.
I just have an irrelevant question if you wouldn’t mind. How could you get snap or Matlab to plot this Acquisition time vs Perpendicular baseline chart ?
If you are using GMTSAR then preproc_batch_tops.csh will generate a .ps file with time x baseline graph.
Unfortunately my study area isn’t available yet for GMTSAR data base. I am using Snap and Matlab_operated StaMPS
In SNAP you can generate a baseline graph from your InSAR Stack. Is this what you are looking for?
For the coregistered stack you can open View/Tool Windows/Radar/InSAR Stack and go to the tab “Baseline Chart”
I have checked this out earlier and this method requires a single stack file of all the input co-registered scenes, while the automated snap processing produces multiple stack files of co-registered master-slave pairs which isn’t a valid input for the baseline chart tool in SNAP. I do, however, appreciate attempting to help
Are you doing SBAS? (Multi-Master?
I’m not too sure how I can help in that case. A custom python script would probably be suitable, you could use matplotlib to generate your graphs. Good luck.
