DATA STRUCTURE AND NAVIGATION SYSTEM USING IT

摘要

PROBLEM TO BE SOLVED: To provide a data structure capable of quickly outputting a distance from a recognition target place to a control target place when detecting the recognition target place with reducing a load on a navigation system. SOLUTION: The data structure includes coordinate data of the control target place; control target road data defining a control target road to recognize the recognition target place; recognition target place data for recognizing the recognition target place existing in the control target road; and distance data defining a distance from the control target place to recognition target place. The coordinate data, control target road data, recognition target place data, and distance data are related at each control target place. COPYRIGHT: (C)2008,JPO&INPIT
