load.sentinel1 error

[natasnat]

It is currently not possible to upload Sentinel-1 scenes.

In GUI mode I get the error POLARISATION' KeyError in Spaceborne_GDAL.py (line 241).

On the the command line I get ERROR: manifest.save file not found! ERROR: 'bool' object is not iterable TypeError in LayerData.py (line 44).

But my S1 SAFE folder has the manifest.save file and as I see it, PyRAT only needs {'dir': '', 'swath': 1}.
In debug mode:

SENTINEL-1 IMPORT {'dir': '', 'swath': 1}
ERROR: manifest.save file not found!

Sorry for being so slow. I checked that module and indeed there is a bug, but I don't get those errors!? Anyway, there was a problem of gdal switching apparently the key from "POLARISATION" to "POLARIZATION". This is fixed now. Can you please try again if it works now?

Hi, I've tried it but it still doesn't work. I get the error:

SENTINEL-1 IMPORT {'dir': '', 'swath': 1}
ERROR: manifest.save file not found!

ERROR : 'bool' object is not iterable
TypeError in LayerData.py (line 44)

Thanks for testing! The error you get now is pretty clear: "manifest.save file not found". This file should be (to my knowledge) always part of the dataset directory - it contains all the meta data. Are you sure that you have a complete product? From where did you get the data?

In any case, there is little I can do here, because we use the GDAL library for reading Sentinel-1 data, and obviously it seems to require this file. You can, however, try to read directly the geotiff files somewhere hidden in the product directory. But I'm not sure if this will give reasonable results.

[natasnat]

Yes, I am sure. I see the file manifest.save in the directory, but PyRAT cannot open it. I get the data from Alaska Satellite Facility.

[birgander2]

The current code expects the manifest.save file to be located in the main product directory (e.g. S1A_xxxx/manifest.save). The error you get should occur if the file is not there (or has length zero). Can you post me a directory listing of your product? Something seems to be different.

[natasnat]

This is strange, the manifest.save is in the main product directory (e.g. S1A_xxxx/manifest.save). I have checked that the manifest.save is not empty.

Here is an S-1 scene I tried to load in PyRAT to download as a link (I downloaded it from the Alaska Satelite Facility): https://upload.uni-jena.de/data/678f6523c28df5.75658275/S1A_IW_SLC__1SDV_20230829T054229_20230829T054257_050086_0606E8_2431.zip

Thanks!

I have no problems (except that only the VH channels loads...)

[91m ERROR : 'POLARISATION'
KeyError in Spaceborne_GDAL.py (line 241)[0m

Am I doing something wrong?

[birgander2]

Ok, this looks at least different and the manifest.save file seems to be found. I get the impression that both "POLARIZATION" and "POLARISATION" is used as a key (I changed that)? Strange. Needs another fix, and I'll try to get the missing channel, too.

In any case, don't expect too much for IWS data. This reader is very basic and does not mosaic neither bursts nor swaths.

[natasnat]

Alright, thank you anyway!
