- set raster bounds/resolution with g.region, - import with v.in.ascii,v.in.ogr + v.to.rast, or r.in.xyz, - then one of the methods shown here: http://grass.osgeo.org/wiki/Contour_lines_to_DEM (r.surf.contour is my favourite, but there are a number of choices) - export raster with r.out.gdal > After importing the data points, I do not see anything at > all visually in GRASS GIS Map Display. see also http://grass.osgeo.org/wiki/Importing_data Hamish _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
