DEVICE FOR CONSTRUCTING DATA BASE FOR THREE-DIMENSIONAL MAP DISTRIBUTION, AND THREE-DIMENSIONAL MAP DISTRIBUTION SERVER

摘要

PROBLEM TO BE SOLVED: To realize transmission of a three-dimensional map in which representation as the map is not spoiled by the same control system without depending upon various display performance nor line performance.;SOLUTION: A three-dimensional map distribution server 300 is equipped with a terminal performance storage section 302 which stores terminal performance data, a display range determining means 301 for taking group data out of a group database previously stored with grouped group data by a device 100 for constructing the database for three-dimensional map distribution so that the amount of data of shape data included in the same group is less than a designated data amount, and specifying group data within a range corresponding to the terminal performance, and a transmitting means 303 of taking the shape data corresponding to the specified group data out of the three-dimensional map database stored with shape data and transmitting the shape data to a three-dimensional map display terminal.;COPYRIGHT: (C)2006,JPO&NCIPI
