Hello, I was looking for information related to the limitation of roughness changes and found this topic. If it is not suitable, please advise me if I should open a new one, ok? I was wondering how WASP manages a "high resolution" roughness map with several roughness changes (more than 10 changes in a short distance). Does WASP do some rounding, resampling or down sampling in order to establish a maximum of 10 changes inside length/area of coverage it needs to consider for its calculation? Or it simply stops to consider the roughness when it "counts" the 10th change? Or, it does exactly what Rathmann was explaining above: it calculates "effective roughness values" which will be representative of some ranges in terms of distance. Then we would have maximum of 10 ranges (and 10 effective roughness values)? Thank you in advance, Guilherme.

Hello, Rogier It worked!!! Thank you very much for your help! Best regards, Guilherme

Dear Rogier I work with my colleague Dulce and I was also trying to run the tool you shared with us "Get Worldcover landcover polygons". I think we managed to solve the problem indicated previously but we are now having a different error message in our log. At first, it was showing us below message: "(...) Results: {'OUTPUT': 'C:/Users/guilherme.simoes/AppData/Local/Temp/1/processing_knVPBu/0e641317d5d64010967656d3c343bdaf/OUTPUT.gpkg'} Clipping to bounding box... Feature (562) has invalid geometry. Please fix the geometry or change the Processing setting to the "Ignore invalid input features" option. There were errors executing the algorithm. There were errors executing the algorithm. Execution failed after 5.83 seconds (...)" But, then we tried setting a CRS in UTM (with its Zone identified) but it continued showing the same message. Later we tried changing the setting in order to "ignore invalid input features" and it showed another error message: "(...) CRS is EPSG:32633 Traceback (most recent call last): File "C:/Users/guilherme.simoes/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\wasp_scripts\processing_provider\worldcover.py", line 209, in processAlgorithm if clipping_layer.crs().isGeographic(): AttributeError: 'NoneType' object has no attribute 'crs' Execution failed after 0.01 seconds (...)" Do you know what could be wrong? Thank you for your help! Guilherme.
