I think you need to interpolate and not simply convert vector lines to raster lines. Make sure lines have an attribute with elevation (or z coordinate) and use e.g. v.surf.rst module.
Māris. Interpolating the vector contour file before rasterizing makes sense to me, too. Never before having to convert a vector elevation contour file to a raster file I'd no idea which v.surf.* module to apply. The vector file has a ContourEle attribute with the elevation values. I'm taking your advice and will use v.surf.rast. This project has more topography data issues than any I've encountered since I started using grass with version 4.0 (all integer, all CLI.) Very much appreciated, Rich _______________________________________________ grass-user mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/grass-user
