Postal route system and method for fast algorithm of the shortest path in the same

摘要

This invention provides a method for searching the shortest path between two points in a geographics information system. In a postal route system and method for fast algorithm of the shortest path search with direction in the same according to the present invention, in order to serve an application service associated with the method for fast algorithm of the shortest path search, a map and an associated information are constituted by a database through which the process to generate the shortest path is performed so that it is possible to provide services utilized in such as postal delivery, transport information system and general road information guide which require the information on the shortest distance.
