You can SubSet or Collocate or use Mask(s). Native functions in the interface, callable by GPT and/or snappy. So basically you should be more than fine with these options.
For Sentinel-1 there are other options for Interferometric stacks.
Snappy is Python binding to SNAP Toolbox or rather the other way around and GPT is command line tool that comes with SNAP Toolbox basically it is the Toolbox without UI.
In the regular UI these options can be found under the “Raster” Submenu.
Hello @ABraun and @marpet
I have an issue with clipping my processed sentinel1 image. I will be using this data for crop classification and I have a polygonal shape file for the AOI.
I used the land/sea mask and got a weird result. I am attaching the screenshots below, can you please look into it?
1st image shows my polygonal shape file.
2nd image shows the parameters
3rd image shows result1
4th image, i have selected the option “invert vector” incase it changes my result
5th image shows the same result as the result1
I even exported the SAR image into tiff in QGIS and the file size is 7 GB, is that normal? I am using GRD format. Also I tried clip raster by mask layer in that but it shows the following error.
Regarding the files size. Your scene is quite huge. Depending on the data type of the bands this might be.
You could try NetCDF4-CF as data format. This might compress the data better.
For such big geotiff files compression should be enabled by default too.
Maybe something went wrong.
Could you send your log file, if you still have it?
See here on [how to find the log files].(https://senbox.atlassian.net/wiki/spaces/SNAP/pages/1898053693/SNAP+FAQs#How-to-find-the-log-files?)
I do not have the log files now. But, this file which is loaded in the SNAP is in the format of BEAM-DIMAP.
I tried the inversion option incase if there is sth wrong with it.
What shall I do? Shall I export it as Netcdf4 and then import it in Netcdf4 and later apply masking on that?
If that doesn’t work either, do you know how can I load Beam-Dimap into QGIS as Geotiff? I tried it but the clipping raster by mask layer gives the above error.
