Yes Chris, you are right. Actually my purpose is to make a bathymetric prediction of a given position, with the help of the contours and sounding points at hand. I just thought that it would be a better idea to take shortest distances in calculations (maybe the Kriging) rather than using pure lat-lon values. So does it make sense to use the geodesic distances for the closeness criteria? _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
