HyP3+Mintpy+GACOS: Error in correct_troposphere with GACOS #1265

Open kiritofaker opened 2 months ago

kiritofaker commented 2 months ago

Description of the problem

An error occurred when I used Mintpy to do SBAS on the interferometric pairs derived from HyP3. But while executing the correct_troposphere step the following error is encountered. I downloaded the GACOS file with Binary grid format which is larger than range of cropped interferometric images to do the correct_troposphere.

Thank you!

I don't think we support the gacos correction for hyp3 products yet. If you could provide an example dataset as below, here publicly or to me privately at yunjunz@outlook.com, I could add this support when I find time.

Because the file size is so big, thus, i uploaded the necessary file to Baidu Netdisk, the file package includes timseries.h5, geometryGeo.h5 and GACOS data. the link is: https://pan.baidu.com/s/1iV45Szn4ncrgjY_ftzurVA?pwd=LMY1 code：LMY1 Thank for your help！
