Method for integrating road names and points of interest in source data

Abstract

The present invention is directed to a method for integrating road names recorded in a source data, particularly comprising steps of merging all interconnected segments having this road name into a user road group and merging these user road groups if they belongs to the same physical road entity. The present invention also relates to a method for integrating points of interest recorded in a source data, particularly comprising steps of, beginning from node with highest priority in the tree to the other nodes one at a time, finding nodes with same point of interest to redirect all child links of lower priority node to higher priority node among the same point of interest nodes and delete link between the same point of interest nodes; creating geometry relationship based on above new arrangement.

Dependencies are inferred from the claim text.
