Geocoding problem in alos2App.py #816

Open Song-Yuqi opened 9 months ago

Song-Yuqi commented 9 months ago

Hi all, I came across a problem about geocoding when I tried to use alos2App.py to process interferograms of two ALOS2 UBS images. I used DEM of 30 m resolution for coregistration and geocoding, and set the multilooks as 4*6. However, the resolution of the output geocoded results are also 30 m, in other word, it won't consider the multilooks I set, but resample the results to the resolution of DEM. Here shows the working folder:

And here is the alos2App.xml configuration file:

And I use the command alos2App.py --steps. Could you please tell me how I can fix this problem? Thanks so much!

That's not an ISCE issue.The software geocodes the data with the same posting than the DEM.
