I have done this with vector before, but now I have 2 raster layers:
1 raster layer that refers to land use: urban, forest, water, agriculture
1 raster layer that was classified in 3 classes for flood risk: low, medium, high.
What steps I have to do to get a new raster layer of only urban land use which is situated in high flood risk?
And how to find the most land use that is situated inside the high risk zone?
I spent days thinking of this but I don't really have any experience with spatial analysis using rasters.
