Abstract

Currently, the components of the GIS have been physically run on a stand-alone system. With rapid advances in internet technology, GIS users require that they are able to not only access they heterogeneous and remote GIS database as well as their own information, but also share them. However, these GIS have the defects that can not handle formats different from own data format. Therefore, in this paper, we propose to integrate the components of the heterogeneous and remote GIS using CORBA in order to solve these problems, which is a distributed object technology, the mediator and wrapper technology in client and server layers.

기존의 지리정보시스템을 구성하는 컴포넌트들은 물리적으로 단일 시스템에서 동작되어 왔다. 인터넷 기술의 급속한 발전으로, 사용자들은 각각의 지리정보시스템 자체 데이터는 물론, 이질적인 다른 여러 지리정보시스템의 데이터베이스에 접근을 요구하며 지리정보의 공유를 요구하고 있다. 그러나, 많은 지리정보시스템은 자체의 데이터 포맷과 상이한 데이터를 처리하지 못하는 단점을 가지고 있다. 따라서, 이 논문에서는 이러한 문제를 해결하기 위하여 분산 객체 기술인 코바 미들웨어를 이용하고, 클라이언트와 서버 계층에 조정자(mediator)와 랩퍼(wrapper) 기술을 도입해서 이질적이고 원격의 지리정보시스템을 통합할 수 있는 시스템을 제안한다.
