As the urban scale changes and the construction technology develops, the living space is being expanded in three dimensions. However, despite the development of construction technology represented by the appearance of skyscrapers, damage to high rise buildings with dense population can be rather high. In order to solve such a situation, digital twin technology that can control and predict the real world in real time can be an alternative, and it is necessary to utilize pre-constructed spatial information actively. Therefore, this study aims to provide a standardized data model for using existing such information as well as various information produced in the future to the building disaster prevention field. To this end, we developed a data model that extends the CityGML standard, a representative city information model, to disaster prevention. ■ keyword :∣CityGML∣Geospatial Standard∣Disaster Data Model∣ * 본 연구는 행정안전부 공간정보 기반 실감 재난관리 맞춤형 콘텐츠 제공 기술개발사업의 연구비지원(과제번호 19DRMS-B146826-02)에 의해 수행되었습니다. 접수일자 : 2018년 11월 09일 수정일자 : 2019년 03월 20일 심사완료일 : 2019년 04월 09일 교신저자 : 김장욱, e-mail : jango@wavus.co.kr 건물 방재 분야 정보의 상호운용성을 위한 데이터모델 개발에 관한 기초연구 31
