3차일 CIS 소프트웨어를 개발하기 위한 기술로는 공간데이터처리 및 공간분석기술, 컴퓨터그래픽스 및 가상현실 기술에 이르기까지 다양한 연구가 요구된다. 지리정보 가시화(visualization)에 관한 연구는 여러 GIS 응용분야에서 주요한 부분이 된다. 현재 2차원 기 구축된 데이터를 이용하여 3차원으로 가시화 및 분석을 수행할 수 있다는 것은 데이터와 소프트웨어 재사용 및 비용측면에서 중요한 의미를 가진다. 본 논문에서는 한국전자통신연구원에서 개발한 Mapbase 컴포넌트에서 빌딩 레이어 3차원 모델링 방법과 시설물의 다양한 상세도 제어가 가능한 LOD(level-of-detail) 모델러와 3차원 데이터와 최소한의 3차원 부가정보(빌딩높이, 도로폭등)를 이용하여 규칙기반 모델링(Rule-Based Modeling)을 통해 3차원으로 모델링 해낼 수 있는 3차원 장면 모델러 컴포넌트 설계방안을 제안한다. 장면 모델러 컴포넌트 분석을 위해 처리하는 이력 데이터, 수작업 3차원 모델링 여부, 소프트웨어 재사용성, 상호운용성, 구축 비용 등을 기준으로 분석하였다.
