NEST Software Tool – Help Required

Asked By claire esseck 20 points N/A Posted on - 08/14/2012

Hi experts

I get a problem in Interferogram generation within NEST 4B.

And I am applying the complex picture of TerraSAR-X to make an interferogram. 

Also the earlier steps are well, actually I did this coregistered_stack, but when I try to go to "Computation of complex Interferogram", I get an error message at the "2-interferogram" table.

The detail of the error message does not exist. Actually the software shows the error image in red color by written "2".

What is the reason of this error?

Please help me to solve it.

Thanks a lot.

NEST Software Tool – Help Required

Hello Claire,

Try the following workarounds and see if they will help resolve the issue:

Solution 1

• Go to the terminal and type the following: sudo apt-get
• After that you can install jblas

Solution 2

• Try applying a PRF correction to the application.
• Try reprojecting both the images that you are working on into map coordinates with the use of the reprojection tool.
• Get rid of the intensity as well as the phase bands from the products that have been projected.
• Try coregistering at coarse well as fine scales by increasing the number of GCPs.

Hope this helps.

Regards,

Carl
