It already exists in fact: - gdal_rasterize : will produce a DEM with the contour line stroked, and with holes between them - gdal_fillnodata.py : will fill the holes with interpolated values > > V. > > > _______________________________________________ > gdal-dev mailing list > gdal-dev@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/gdal-dev -- Geospatial professional services http://even.rouault.free.fr/services.html _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
