Hello everybody on the list! I am a "occasional" grass gis user and I'm stuck with a relatively simple task: I have a high-res vector layer describing only one category (Corine Land Cover map for "broad-leaved forests", 311) and I want to rasterise it in a low-res 8-by-8 km raster map where the value stored on each cell is the area (or, that's the same, the share of the area) that the vector cover within that cell. So each pixel/cell would have a value ranging from 0 (no broad-leaved forest at all) to 64 (all the area of the pixel is covered by broaded-leaved forests). I already managed to get the region with the right cell dimension, add the area geometry to the vector and load it in grass, but I don't know now how to rasterize it (v.to.raster seems to me to not offer the option to put the area, but only a specific catgegory, but maybe I am wrong??).
Thank you for any hint you could provide me. Antonello -- Antonello Lobianco INRA, Laboratoire d'Economie Forestière 14 Rue Girardet - 54000 Nancy, France Tel: +33.652392310 Email: [email protected] http://antonello.lobianco.org
