r.poly -

r.poly extracts area edges from a raster map layer and converts data to GRASS vector format. The program first traces the permieter of each unique area in the raster map layer and creates vector data to represent it. The cell category values for the raster map layer will be used to create attribute information for the resultant vector area edge data.
