Hi, I'd like to ask a question related to another question I was asking recently about converting contour vectors to rasters and creating a DEM from the raster contours using r.surf.contour.
My supplied vector contour layer has 20m intervals between contour lines. When I convert this to raster, the smallest region resolution I can use is 5m, otherwise v.to.rast runs out of memory. When I use r.surf.contour to create the DEM from the raster, which region resolution makes sense then? I set it to 20m because of the contour interval, but I'm starting to think that's not the best option because the interpolation between two contour lines should be as fine as possible. Any thoughts? Thanks Hanlie _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
