摘要:
A method and system for searching for points of interest along a route is disclosed. A relation that includes records that associate link identifiers, point of interest identifiers, and distances between the links and the points of interest is generated during the compilation process of a first version of a geographic database. The relation is stored in compiled database products. When a compiled database product is being used by a navigation system, for example, navigation application software programs use the relation to accurately and efficiently find points of interest along a computed route. Navigation systems can also use the relation to service skyline queries and responsively generate skyline graphs of points of interest.
