Abstract
A method and system are disclosed for the merging of multiple map databases. These multiple map databases can be stored on separate media. Each map database is comprised of whole parcels and conforms to a baseline parcelization pattern. At run time in a navigation system, a single parcel index is constructed that contains references to parcels from the multiple map databases. References to parcels use a combined media directory covering all media objects. The combined media directory is created by merging tables of contents from each media object. This method can be used to incrementally update a geographic database.
