Hello,
I’ve recently started experimenting with ALOS-1 and I’ve been using the suggestions from previous ALOS-1 threads. I’m just experimenting with ALOS-1 data and I want to use it with a timeseries analysis eventually such as SBAS or PSI. To my knowledge, there is no major displacement in my test data.
My output seems to be good however is there anyway to fix the ramps using SNAP or other freely available software? From what I’ve seen there is ISCE but I’m still trying to install the open-source version on Github. The installation process is a bit complicated.
If there is also any other feedback regarding this output please do share. This is my first time working with L-band data. Thank you.
