SDR error regarding the watershed results table, only when drainage is provided

Software Support

Dear Sirs,

Version v.3.15.0
When I provide the SDR model with the Drainage in tiff format the watershed results table has 0 in all fields.

I didn’t have this problem with Version 3.14.3.

Thus, check it please,

Best wishes,

Dimitrios

Dave many thanks for your prompt reply.

I am sending you the requested files along with the Drainage.

It will be great to give me some solution.

@Dimitris , thank you for sharing this information. Since you have determined that the drainage input is the only difference between these runs, it may be helpful to look at some of the other outputs. Specifically, stream_and_drainage.tif. Does this raster look appropriate? If not, how about intermediate_outputs/masked_drainage.tif? And intermedate_outputs/'aligned_drainage.tif'?

If those look okay, how does stream.tif compare to stream_and_drainage.tif?

The drainage raster you shared looks okay to me. If you don’t notice anything strange about these output files, we may need you to share all of your input data in order to reproduce the issue.
