Abstract
A method and system for updating geographic databases used in systems that provide navigation-related features are disclosed. An original version of a geographic database is formed in which the data are organized into parcels. An updated version of the geographic database is formed that includes updated data. The updated version is organized into parcels so that the data in each parcel of the updated geographic database represent the same features that were represented in a corresponding one of the parcels of the original version. Incremental update transactions are formed that identify the differences between the parcels of data contained in the updated version of the geographic database relative to the parcels in the original version. The incremental update transactions are transmitted to the systems that provide navigation-related features where they are used to form updated parcels which are used in place of the corresponding parcels from the original version.
