you are the scientist
If you want to use the rasters from SNAP in a GIS you can simply open the .img files in the data folder of the BEAM-DIMAP format. I suggest this because conversion to GeoTiff has some negative aspects:
I am not scientist, just s/w engineering!!!Anyway, we developed many analysis with IDL s/w read the geotiff format.We do not have GIS.
Just be aware of the mentioned error sources, especially the data type.
I have zone question, If product is between 2 zones, which zone you will use forcreating the xml using gpt command line? where exactly the parameters to define the zone from GRD or SLC products?
you define the UTM zone in the projection step, usually in Range Doppler Terrain correction. Generally you take the zone with the larger coverage in your scene.
Yes that is work perfect.I build the xml not using the snap. where I get information to get zone?
I would first build a graph in SNAP then export it as an XML. Then you see how the parameters are compoed.
Do all the processing in BEAM-DIMAP and export to Geotiff in a separate step only after the processing is done. Not doing this can cause strange problems.
How to processing data eliminate the bad data on the both side/top/bottom?I did by using subset, but that is manual, I would like to automate.
