Great, thank you. The logfile includes this error, which is probaby the source of the problem.
ERROR [errno 1] The transformation is already “north up” or a transformation between pixel/line and georeferenced coordinates cannot be computed for C:/Users/david/Desktop/PLUS/UE Stadtökosysteme Urbane Biodiversität/data/raster_modis/modisconverted2.tif. There is no affine transformation and no GCPs. Specify transformation option SRC_METHOD=NO_GEOTRANSFORM to bypass this check.
This is new to me, but I would start by investigating the coordinate system & projection of
modisconverted2.tif Does anything seem strange when you view it in GIS? If you created that raster from another raster, it might be good to go back to the original, investigate it’s projection, and redo any steps you took. The LULC raster seems like a valid input, so if you see any differences between it and this problematic raster, that could be telling also.
If you can’t make any progress, feel free to share your input data and we can take a closer look.
