Hello! I am running DelineateIt to get the watershed from my raster DEM but I get the error "AttributeError: ‘NoneType’ object has no attribute ‘GetRasterBand’ " when I run the process. Do you know what this error means and how can I fix it?
I have already used the same DEM raster file to create the streams with RouteDEM and worked without problems. So, in principle, I understand that the error should not be caused by the file
Thank you very much in advance for your help.
What do you expect to happen?
I hope it works without errors.
What have you tried so far?
I checked the forum to see if this error had already been posted.
Welcome to the forum and thanks for posting. I’m not quite certain what is happening but have a few questions from looking at your log.
It looks like the file might be located in a Microsoft OneDrive Cloud location. Could you say if the DEM is physically located on your computer or if it’s stored in the cloud?
It looks like the tool is delineating a lot of small watersheds. Could you try increasing the snap distance to something a bit larger? That value is in pixels, so it’s hard to say what makes sense because it depends on the resolution of your DEM. Just for debugging I would try setting that value to 500 and then see if the model completes and inspect the results.
