Abstract

A technique for structuring a navigation data base in order to support incremental data updates is provided. A method implementation of the technique includes the steps of providing at least two data levels, wherein a first data level is associated with route links representing road segments of regional distance roads, partitioning the first data level into local tiles, wherein each local tile is associated with route links representing road segments of regional distance roads for a specific local geographic area, and interlinking those route links of neighboring local tiles that represent road segment portions of a regional distance road extending over neighboring local tiles.
