Dear Sir
Impressive work, congratulations.
I want to ask you, do you compared your altitude with the actual altitude.
And what accuracy have you achieved?
Thanks
SNAP is installing the old version of SNAPHU i.e. 2.0.4 using plugins while latest version is available 2.0.6 (Aug. 2023 release). I am talking about particularly windows. Linux version can easily be done with new version, but not with windows. Request SNAP software developers update SNAPHU windows version.

Dear ABraun:
I have problems in using Snaphu-unwrapping with the main objetive of obtaining a DEM. I have exported the files well, but when I use Snaphu-unwrapping it does not work. Then, following your tutorial, I go to Manage External Tools and enter the export directory in the variable USERPROFILE and OK. But if I change the directory, the Status gives error. I show you:
If I give RUN, althought it begins to run, I do not get nothing after more than 10 hours.
On the other hand, muy phase and coherence are not good, because there is vegetation in our site (Asturias, North of the Spain). I have done all the proccess from your tutorial included Golstein filtering (GF). Should I do Multilooking for trying to improve a bit that? And ¿When Multilooking must be applied, before of after Golsdtein filter? Because in your paper you put before but in this forum the people seems to do it after G filter…And when using multilooking, ¿it is correct chosing Phase and coherence and leave the rest of the items for default?
Hello
I am working on subsidence on a coastal system and used S1 imagery from august 2021 to august 2923 at a 6 days time interval. Once downloaded, I followed the steps below:
1 - TopSar Split
2 - Apply an orbit
3 - Coregistration to define the master file
4 - Create a stack
5 - Enhanced Spectral Diversity
6 - Interferogram
7 - TopSAR Deburst
8 - TopoPhase Removal
9 - Multilook
10 - Goldstein filter
11 - Snaphu export
I would like to know how to unwrap the stack. I tried once and only got 1 unwrapped file. I think about modifying the input in the “snap.config” file, what do you think about it ? How to unwrap all phases ?
Thanks
