despeck.py usage #55

Closed stoormgeo closed 2 years ago

stoormgeo commented 2 years ago

What is the best way to use despeck.py? It gives an error then on startup. The same window sizes used.

despeck.py -i /data/merged/fringe/coreg_stack/slcs_base.vrt -o /data/merged/fringe/Despeck/despeck -w /data/merged/fringe/KS2/count -l 100 -r 100000 -x 25 -y 35 -b 1

Input Dataset: /data/insar/Proc/Specgeo/Marre/proc/merged/fringe/coreg_stack/slcs_base.vrt Weights Dataset: /data/insar/Proc/Specgeo/Marre/proc/merged/fringe/KS2/count Output Dataset: /data/insar/Proc/Specgeo/Marre/proc/merged/fringe/Despeck/despeck Window size: 25 35 Memsize: 100000 Mb Blocksize: 100 lines Master band: 2 Number of uint32 bytes for mask: 114 Number of rows = 4840 Number of cols = 13909 Number of bands = 17 Number of bands mismatch for weights and window size Exiting with error code ....(108)

The wts/nmap.hdr file should report what window sizes were used to generate it in the first place. You are providing it the count file, when it needs the wts/nmap file as input. This looks like a mismatch in x and y arguments. And you are requesting 100GB of RAM with the memory option.

Thanks Piyushrpt, Recalculated with a smaller window size without any errors. The output is a file with the .hdr How can I use further with evd.py/sequential.py? Thx

Those already use the despeck operation internally for all computations. This is just a utility to despeck a SAR image / individual interferogram using the neighborhood map - for visualization or other applications that build on it.

Ok. Thanks for guidance!
