Matlab script for determining vertical displacement from snap-stamps ps_insar ascending and descending data

if you refer to StaMPS - there is currently no implementation of this approach with open software. Something similar has been discussed here: Need help with re-writing StaMPS to Python

But there are other open tools which support different multi-temporal approaches

I should have been more specific ABrain. That is what I meant. I will check this tools up.
Thanks a lot!
