You could try this: https://github.com/gina-alaska/dans-gdal-scripts/wiki/Gdal_trace_outline to get it 1. git clone https://github.com/gina-alaska/dans-gdal-scripts.git 2. go into the directory 3. ./configure 4. make 5. make install It has a parameter-controlled douglas-peucker algorithm built in, and it is a lot faster than gdal_polygonize, too! Hope this helps Graeme. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
