<http://gis.stackexchange.com/questions/146527/dem-with-bathymetric-contour-lines-in-grass/146658?noredirect=1#>
I am trying to create a DEM from a bathymetric contour lines. Contours are in vector format and the elevation value is negative (integers). To create the surface I have converted the contours in raster (v.to rast) and then I have used r.surf.contour, but It doesn't work (there is no error but the resulting output raster is exactly the same as the previous one, without any interpolation). This are my region settings: g.region -p -a raster=contours@iiaa nsres=1 ewres=1 projection: 1 (UTM) zone: 30 datum: etrs89 ellipsoid: grs80 north: 4818927 south: 4791484 west: 486512 east: 601275 nsres: 1 ewres: 1 rows: 27443 cols: 114763 cells: 3149441009 I need a DEM of very high resolution of a wide area. I am using a computer with large capacities for it. Could someone help me please?
