Re: [GRASS-user] v.to.rast gives empty raster layer

Hi Moritz, I'm not sure what you mean by 'Maris' first part of the solution'. I saw only one part to Maris's suggestion (refining the region's resolution) because I said in my initial mail that I had set extents of the region to the contours_20m vector layer. Initially I did have a resolution of

[GRASS-user] DEM resolution from r.surf.contour

2011-05-04 Thread Hanlie Pretorius
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,
