Topographic Phase Removal COSMO-Skymed

Microwave Toolbox Problem Reports
#1

Hi all,
I systematically got the following error when trying to remove the topographic phase of interferograms produced from COSMO-Skymed HImages (the coregistration and interferogram formation work well on the other hand):

Are COSMO-Skymed images supported by the topographic phase removal tool?

Thank you,

Antoine

maybe no DEM is found for your region.
Where is your data located?
Did you chose DEM AutoDownload?

#3

DEM exists over the area (and it is on auto download), I manage to carry out the topo phase removal on S1 images, but with COSMO it doesn’t even start the process, I directly got this error. That’s why I’m thinking that the tool do not support COSMO images, but I didn’t found a definitive answer on esa’s websites, so I’m still hoping a solution exists… ? :slight_smile:

Thanks,

Antoine

#4

Have you resolved your problem ?

Because I have the smae one using CSK or ERS data.

Thanks

Nope, I didn’t find anything new, I suppose that CSK images are just not supported by the topo phase removal tool… You should look into software like DORIS, ROI-PAC or ISCE I suppose.

Regards,

Antoine

Dear ABraun. Do you happen to know from where I can get roi-pac software as the openchannelfoundation is down for good. I need to do SBAS and as SNAP doesn’t do it, so I have to look for other alternatives. I tried GMTSAR but it gave me so many errors. I would very much appreciate it if you could help me on this matter.
