Spatial data retrieval system, spatial data retrieval method and data management method, and computer-readable recording medium

摘要

PROBLEM TO BE SOLVED: To provide a spatial data retrieval system capable of retrieving spatial data without changing a program on the side of a client even when there is an added or stopped spatial object on a network.;SOLUTION: When starting or stopping the spatial object, it is reported to a spatial object monitoring processing means 31. A master meta-data access processing means 22 collects the meta-data of spatial data stored in the spatial object registered in a spatial object managing table 32 and prepares master meta-data. An application server 20 receives the retrieval request of spatial data from a client 50, executes retrieval while using the master meta-data 23 and returns the acquired spatial data to the client.;COPYRIGHT: (C)2001,JPO
