SPATIAL DATA CLEARING SYSTEM BASED ON THE OPEN TYPE GIS

摘要

PURPOSE: A spatial data clearing system is provided to share and clear the spatial information and service and to be based on the CORBA implementation specification of open type GIS which is proper for supporting compatibility among the different kind of platform and reciprocal operation nature. CONSTITUTION: A spatial data clearing system comprises: a spatial information clearing server(100) having an information who provide the spatial information and service which the client wants to use and where the provider exists; and a basic component(140) for a spatial data clearing being arranged at a data provider component(120) based on the COM, an application component(130), a base component(110), and providing data and service through the interface based on the CORBA and mapping to make the spatial information and service provided by each component be used platform independently at dispersion environment, wherein the spatial information clearing server(100), the data provider component(120) based on the COM, the application component(130), and the base component(110) move together by the dispersion environment, and wherein the client is provided with the spatial information and service from the data provider component(120) based on the COM, the application component(130), and the base component(110) using the information provided by the spatial information clearing server(100).
