Hi, I have a series polygons located in a mountainous terrain. I can convert the 2d vector into 2.5d using v.drape and a DEM, however, it only converts 2D vector point or line data and not areas. My task is to calculate the area in hectares of the polygon incorporating the elevation/surface of the polygon. I then need to subdivide the main polygon into smaller polygons using a preferred area in hectares.
How to calculate 2.5d polygon areas in grass? -- cheers, maning ------------------------------------------------------ "Freedom is still the most radical idea of all" -N.Branden wiki: http://esambale.wikispaces.com/ blog: http://epsg4253.wordpress.com/ ------------------------------------------------------ _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
