Abstract
A method is described for locating a destination in a digital map database using a query. If the query does not find the destination, the method queries a second, more recently updated, database for the destination. If a destination is found in second database, then the location of the destination that was found is used to find a destination in the original database that is nearby to the location of the destination found in second database.
