    28 To properly convert a vector coverage containing overlaps to a raster coverage, you need raster to be able to overlap also. This is also convenient of you want to model surface who have their own identities (one raster per object like a polygons in a vector layer) but are better represented by varying raster or fuzzy objects (like variable intensity fires, variable depth lake or overlapping animal territories).
