Abstract: A method and system for updating a digitized map. An operator-controlled vehicle provided with an onboard computer and a navigational transmitter unit is dispatched to a location provided on the map near to an unknown location. The vehicle would then traverse the segment between the known intersection and an unknown intersection while it is being tracked by the navigational tracking unit. When the unit reaches the unknown intersection, the address range as well as the street names of the intersection are verbally inputted into the system. The information collected by the computer is then inputted to the central computer which edits this information and updates its central file to produce a new updated version of the digital map.
