WaterMask

[Phil Edda]

Hi, 

I have been trying to generate watermask.h5 to remove the sea from land in my ifgs. I'm processing stacks of sentinel-1 scenes using TopsStack processing (stackSentinel.py) to input in Mintpy. My question is, can I generate watermask.h5 in Mintpy despite there's no waterMask.rdr, waterMask.rdr.rsc files generated during the TopsStack processing? In what processing stage in Mintpy do I need to specify my parameters (AOI) to generate waterMask files? Thanks.

Hi,

It is done during the "network modification" step in the default routine, by reading the geometry file (i.e., the waterMask.rdr or waterBody.rdr)

You can use `generate_mask.py` and your elevation file to make one. According to the --help of generate_mask.py, you can also select your ROI/AOI interactively on the panel:

Best,
