I have a large DTM (5m cell size) and it covers an area of 100,000km2. I need to create contours every 10meters in the dataset. If I tile the dataset and contour each tile, the data, the contours act funny at the edges, hence the need to process the area as one area. Is grass capable of doing this?
Shane, Yes. As long as you have sufficient memory and drive space. You can always set the environment variable in ~/.bash_profile: export=GRASS_VECTOR_LOWMEM=1 which will use available memory and not crash, while running more slowly. If I'm wrong I'm sure we'll both read about it. :-) HTH, Rich _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
