Dear All,
I am new with this software and I have a problem with coregistration TerraSAR-X data, 3 scene.

Problems start at the coregistration. All the 2 slave images failed. Warnings related to cull_points. Which is weird because in other software like SNAP I managed to create the stack. Maybe parameters? I have no idea.

Here attached the log file and lasterror.mat.
Any kind suggestion? I am using the compiled version for windows (very last update).

Thank you
Fatchur

Hi Fatchur,
yours is not the last update. Please update the sw using the manage version module and try again. Should you get again an error, zip lasterror and log files before uploading them

The fact that the operation cannot be performed and no errors are reported,
it does not reveal any bugs,
it simply means that the default parameters you are using are not appropriate for your case.
Firstly, you should check the forum.
A quick search would you lead you e.g. the the following pages
https://www.sarproz.com/groups/sarproz-group/forum/topic/error-in-coregistration-step-with-alos-data/
or https://sarproz.com/manual/coreg_param.html
Plot the images. Check corresponding features. Make sure the searched shifts are enough wide. Change them or use the initial cross-correlation to guide the search.

Hello Dr Periz, I already try to use initial cross-correlation, but it is still failed in coregistration. I use TSX High Resolution Spotlight data, the image dimension is 5563 x 3673. Please help what i have to change again in coreistration parameter? i use this data to measure the deformation on the area.

Thanks
