[Help]: PS processing #49

Open SteffanDavies opened 1 year ago

SteffanDavies commented 1 year ago

I am having issues with sbas.ps_parallel, some indications on workflow would be helpful.

Is ps_parallel supposed to be run after intf_parallel and merge_parallel? Doing so causes {final date}_F{merged subswaths}.PRM missing file error.

FileNotFoundError: [Errno 2] No such file or directory: 'raw_asc/S1_20230530_ALL_F23.PRM'

Removing this file from dates and passing custom dates causes another error:

sbas.ps_parallel(dates=sbas.df.index[:-1])
Exception: "ValueError('mmap length is greater than file size')"

@SteffanDavies There are two new wrappers for Stack.compute_interferogram() added: Stack.compute_interferogram_singlelook() and Stack.compute_interferogram_multilook() for large stack computations. For now, these are available only on GitHub but not on PyPI.
