I need to calibrate a Sentinel image from command line by using the S1TB. My final aim is that of putting the command line in a python script. Can anyone suggest me how to do or any available documentation in order to solve this problem?
You cannot just use the tiff image as your input. It needs to be the whole product which is read by either using the manifest.safe as input or the product in a zip file S1A_S3_SLC__1SDV_20150916T173102_20150916T173130_007743_00AC2C_E08D.zip
If you want to create a subset or only process a single swath or polarization, you will need to create a graph.
