MAP DATA SEGMENTING DEVICE, MAP DATA SEGMENTING METHOD, AND MAP DATA SEGMENTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To easily segment map data required for navigation or the like.;SOLUTION: A range specification means 51 uses one of map data selected from a plurality of map data 31, 32, 33 different in map scale as reference map data, and specifies a segmentation region in the reference map data. A map segmentation means 53 segments the map data including the specified segmentation region from the reference map data, and then segments the map data including the same land area as the specified segmentation area, from at least one of the map data having the map scale larger than that of the reference map data.;COPYRIGHT: (C)2005,JPO&NCIPI
