This is based on 360° being equal to the length of the equator, and for longitudes and latitudes down there it works well enough. But it's already grossly inaccurate for east-to-west distances not farther north (or south) than N +/-45°. -W _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
