ABSTRACT:
A method of organizing map data on a physical storage medium is disclosed. The map data represents geographic features located in a geographic region. The method identifies at least one dense area in the geographic region. The map data representing the geographic features within the dense area have a data size exceeding a predetermined maximum size for a predetermined sized geographic area of the region. The method subdivides the map data representing the geographic features within the dense area into parcels so that the portion of map data contained in the parcel is close to a predetermined parcel size. The method subdivides the map data less the map data representing the dense area into parcels so that the portion of map data contained in the parcel is close to the predetermined parcel size. Additionally, the method locates the map data in each parcel together on the physical storage medium.
