Unable to work with RCM Dataset. #199

Closed sparshgarg23 closed 1 month ago

sparshgarg23 commented 4 months ago

So I am currently working on RCM datasets and I thought of using your repository. Unfortunately the example RCM.ipynb isn't working because when you execute the cell

path = xsar.get_test_file('RCM1_OK1050603_PK1050605_1_SC50MB_20200214_115905_HH_HV_Z010')

The file doesn't download.Whereas when I work with the radarsat 2 example,the file is able to download and I am able to access the metadata.

Secondly,since I thought this was an issue in downloading the file.I provided my own file.The code and structure of the folder is shown below Code

import xsar
meta=xsar.RcmMeta('Name of RCM folder')
in this case it's RCM1_OK2137170_PK2304568_1_FSL24_20221018_123926_HH_SLC

structure_rcm

However doing this results in the following error type error iteration over a 0-d array Any reason why this error is happening?

Hello @sparshgarg23 , I think, xsar is not working because xarray-safe-rcm is handling only GRD and you try to open a SLC product. Do you confirm? For now, it is not in our roadmap to update xarray-safe-rcm for SLC products but feel free to propose a pull request, we would be very happy to review it. Cheers

@agrouaze that's sad to hear.Are there any other python based libraries which can be used to read RCM files in SLC format.

If there is such a python lib, I don't know it.
