OGC는 GIS와 관련된 연구기관과 산업체가 GIS 수요자에게 양질의 지리정보 서비스를 하고, GIS 기술발전을 위해 SFS 명세를 제안하였다. 이 명세는 각각의 연구기관에서 독자적인 데이터 사용하되, 다른 시스템에서도 그 데이터를 사용할 수 있게하는 등의 많은 장점을 부여하고 있다. 그러나, 최근 2차원 지리정보와 더불어 3차원 지리정보에 대한 관심이 높아지면서 3차원 GIS 시스템을 개발하는 연구기관이나 기업이 증가하고있다. 따라서, 이 연구에서는 특정 GIS 시스템이 가지는 독특한 지리정보 데이터를 유지하면서, 다른 환경의 GIS 시스템에서도 운용될 수 있도록 OGC 명세를 수용하고, 3차원 지리정보 데이터를 분석, 관리 할 수 있도록 OGC의 OLE/COM SFS를 확장한다.
