I'd like to be able to overlay a series of polygons over a land cover
raster to ascertain the composition (area or proportion) of the
raster classes within the polygons. I think this should be a rather
So far I don't see a way of doing this directly in Qgis (maybe an
"ftools" for rasters will appear). Have I overlooked something?
I presume this can be done in GRASS (not sure of the procedure yet).
Would the easiest approach be to do this via grass tools in Qgis or
directly in GRASS? Would it be necessary to ship all layers to GRASS
or does Grass Tools allow analysis of Qgis layers on Grass layers?
Thanks for any advice or direction.
