최근 공간정보를 다루는 GIS, SIIS, GNSS, ITS 네 개의 시스템에 대한 통합연계 기술인 4S 기술이 각광받고 있다. 본 논문에서는 컴포넌트 기반의 4S 시스템을 소개하고 4S 기술을 화재, 홍수, 태풍 등의 재난재해 분야에 적용한 시스템을 4S 핵심 컴포넌트를 중심으로 설계하였다. 4S 기술을 이동 환경에서 적용하는 예는 매우 많으나 재난재해 업무에 적용될 경우 매우 큰 효과를 가져올 것이다. 공간데이터를 처리하는 핵심 기술과 재난재해 업무간 공통된 기능은 4S 핵심 컴포넌트로 구현되며, 업무별로 다른 기능은 별도의 업무 컴포넌트로 분리하여 분야별 응용시스템에 따라 사용하게 하였다. 특히 4S-Van 이라는 차량 및 이동단말기 등 현장과 중앙관제센터간에 실시간으로 위치정보와 영상정보 등을 전송하는 방법 및 전송된 정보를 중앙관제센터에서 공간 데이타와 연동.분석하는 방안을 제시하여 신속하고 정확한 상황파악, 의사결정, 지령관제 등을 가능하게 하고 재난재해 분야에 획기적인 업무효율 향상을 가져올 것으로 기대된다.
