Ideally the routing application shouldn't need to ask for clarification once a human asked for a route to a specific address. Now that might not be possible for a number of reasons, e.g. - Ground truth is such that an address actually isn't unique - Incomplete data in the database, exact match was not found - Ambiguous data in the database, same address is distributed over multiple objects in the database Personally I consider the last case to be bad mapping practice. /Markus _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
