Try to get an accurate vector layer of the same terrain, that has recognizable locations that match your raster, load that up, and then use the from map tool, itll be the easiest way.Any suggestions where to find vector maps? All the ones I have found are somewhat squishy in their placement of islands and the details of coastlines. I have tried geological survey websites plus the general commercial web. I have some older maps I may scan in and trace the vectors myself. How do I determine the projections of these maps?_______________________________________________ There's also the global shoreline layers from NOAA: http://www.ngdc.noaa.gov/mgg/shorelines/gshhs.html Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discussThis mail was received via Mail-SeCure System. --
