Abstract

Recently, Construction information is being changed from CAD to BIM, and GIS is extending from outdoor to indoor information. In these circumstances, the needs of continuous use of construction information linked with GIS are growing constantly in stages of maintenance, operation and service as well as planning, design and construction. To this end, it is essential element to represent 3-dimensional large object efficiently in establishing BIM-GIS interoperability platform by combination of construction and spatial information. In this study, we design spatial data LOD for making spatial object and texture by level, and develop weight lightening algorithm of large spatial object.

최근 건설정보가 CAD에서 BIM으로 전환되고 있으며, GIS 분야는 기존 실외공간에서 실내공간으로 확장되고 있다. 이러한 상황에서 건설정보를 GIS와 연계하여 계획 설계 시공의 건설단계는 물론 건설 후 유지관리 및 운영 서비스 단계에서 지속적으로 활용할 필요성이 커지고 있다. 이를 위하여 건설정보와 공간정보의 유기적 결합을 통한 BIM-GIS 상호운용 플랫폼을 구축함에 있어 대용량 3차원 공간객체의 효율적 표현은 필수적인 요소이다. 본 연구에서는 대용량 공간객체를 표현함에 있어 각 레벨별 공간객체와 이에 따르는 텍스처를 효과적으로 생성할 수 있도록 BIM 데이터와 GIS 공간 데이터의 연계활용을 위한 공간데이터 LOD를 설계하고 이를 기반으로 기존의 대용량 공간객체를 경량화할 수 있는 알고리즘을 개발하였다.
