Error in land cover grid

[sanwitiab]

Hello,

I try to process the thermal comfort zone. But when I run shows this error "Land cover grid includes Confier land cover class. Ground cover information (underneath canopy) is required."

Please help me. How to fix it?

Thank you

The land cover in the SOLWEIG model should be ON the ground, i.e. what is underneath the trees. Therefore, the conifer (4) and deciduous (3) class should NOT be present. You should recalss these pixels to e.g. bare soil, paved or grass.

Good evening, I need help to understand what is the reason for this error when running SOLWEIG:

The land cover grid includes integer values highter (or lower)than UMEP-formattedland cover grid (should be integer between 1 and 7). If other LC-classes should be included they also need to be included in landcoverclasses_2016a.txt (Where can I find this .txt file?)

I have created a land use raster with the same resolution and extent as the other layers by including values from 1 to 7 as specified.

In doing other tests, I also encountered this error:
Error in land cover grid: Land cover grid includes Decidiuous land cover class. Ground cover information (underneath canopy) is required.

How to solve it? Thank you

You both need to get rid of your NoData values. Use the Fill NoData Cells found in the Processing Toolbox in QGIS and replace with 1.

Solved thank you very much. The simulation has started.
Now I have only one problem. I do not have a square/rectangular raster but with a non-regular perimeter, filling in the outer values no date setting 1 (as if it were paved) is a great approximation.
I guess I will have to do the land use outside my perimeter.

or you can just ignore the area where you replaced your Nodata values.

Will it affect the interior area?

very little, just in the edges of your study area
