Well, not entirely. Beyond 1 degree of lat/lon from the imported area it will simply return an error. > How could I check the validity of the result? > Is it possible to get the coordinates of the result (or even the > geographical distance from the input coordinates)? The output could certainly be extended to include this fairly easily.

This used to be done and has been lost recently. -- Brian _______________________________________________ Geocoding mailing list [email protected] http://lists.openstreetmap.org/listinfo/geocoding
