Can you check this command, it is perhaps not that you actually used: gdal_contour -a elev -snodata 32767 -i uk-3785.tif uk-contour.shp My GDAL gives FAILURE: Neither -i nor -fl are specified. With -i 100 I have managed to run your commands. Result was 620 MB shapefile with 135020 linestrings and it took several minutes to run it but it worked for me. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
