issue

Dear Alexey,

i wanted to ask that this ongoing step basically is taking a lot of time in PS analysis could there be any solution in order to lessen the processing time.

AlexeyPechnikov commented 6 months ago

You can omit this step or use instead Stack.trend() for polynomial trend detection.

Also, see Stack.velocity() function usage in 'PyGMTSAR SBAS and PSI Analyses: Golden Valley, CA.' and 'PyGMTSAR SBAS and PSI Analyses: Lake Sarez Landslides, Tajikistan.' Google Colab notebooks.
