I am a beginner with the SNAP software and I am very impressed with the functionality of the software.
Recently, I have processed a set of Sentinel 1 data and created elevation through processing.
I tried to export the elevation data in various formats (Geotif/Big Tif, JPEG 2000 etc). The export option creates a 3 band RGB imagery. My intent is to create an elevation grid, which I am not able to.
I am not sure, whether I am missing something here.
I have followed the Stripmap Interferometry Tutorial completely. I have installed the necessary plugin before hand.
I am able to run upto Goldstein filtering without difficulty. In phase unwrapping, I am able to run export without any difficulty. However, I have a problem in running unwrap. The program is executed and at the end it is not giving any message (success/failure). Then I go the next step of import and I get an error message. Specifically, I anot seeing any commands in the following screen. Any help is highly appreciated.
the unwrapping is finished after row 10 column 10. You can chec if it was successful if an img file was created for the unwarapped phase in the export folder.
I just finished the export and want to make sure that the process is completed correctly. Here are the files created after export. Could you please confirm, that this step is completed successfully?
As you see, all others consist of a pair of img and hdr with the same name. The UnwPhase is only available once, because the unwrapping did not finish successfully.
I recommend to use only HH polarization as early as possible. Having HV included does not bring any benefit and makes your processing slower and prone to errors.
first you run the export (good so far)
then you run the unwrapping (not good, because the img was not created)
then you can run the import of the unwrapped phase
I am running unwrap for the last 5 hours and that there is no progress tool bar. I am not sure whether program is still running. Any idea how many minutes it will take for unwrap to run.
I will allow the program to run for some more time.
