I have a reclassified slope rasteraster with 3 values in band 1. My problem is that I want to polygonize thsthis layer, but the surfacessurface is so irregular with a lot of plots in terraces and because of this it becomes in a vector layer wthwith infinite polygons. How
What can doI do to clean up the raster layer to obtain bigger polygons of slope. i Thanks in advance?
