Solweig: No valid DEM selected

[elidamd]

Hi!

I am running SOLWEIG without success. I would like to ask for some tips on how to find out the error (what is wrong with the files). Thanks!

1. Before [plugin version 3.11]
   SOLWEIG was successful with DSM, landcover, sky view factor inputs.
   However, it was returning empty when I added vegetation DSM files (from tree generator tool).
2. Now [updated plugin to 3.19.3]
   I am trying to run SOLWEIG with the same inputs from before, but it gives the error: "No valid DEM selected".
   My dsm had negative values, so I adjusted (raster calculator)
   It is still giving me the error, and no other message that I could understand what is the problem with the file.
   To check the files, I was able to generate the "daily shadow pattern" function (using both CDSM and DSM I am applying Solweig).

• OS: Windows 10
• QGIS Version: 3.22.2
• UMEP Version: 3.19.3
• SuPy Version: 2022.2.17

Thanks a lot!

SOLWEIG need to know the locations of buildings. This is established by either:

• comparing a DSM (ground and building heights) with a DEM (ground heights) OR
• retrieving that information from a land cover dataset

Your error implies that you have no DEM loaded.

Oh, I thought it was an error in the file. Thank you very much!
