Abstract

Facilities located in the underground space are closely related to the sanitation and safety of the city, and the underground spatial information is precisely constructed and used as important information for facility maintenance, safety, and underground space development. In this study, a method was studied to increase the field usability by increasing the reliability of underground spatial information constructed in Korea and used in the field. For this study, the current status of the construction of underground spatial information in Korea was summarized, and cases of the underground spatial information quality grading system applied in the US, UK, Canada, France, and Australia, which are advanced geospatial information countries, were investigated. In terms of field usability, a questionnaire was conducted on the systems, standards, and management methods related to underground spatial information of field experts and consumers working in related fields in Korea, and statistical analysis was conducted to analyze the relevance of the introduction. Through this study, it was concluded that it is necessary to introduce a quality grading system according to the construction method of underground spatial information, accuracy and reliability, and to improve related systems and regulations.

지하공간에 위치한 시설물은 도시의 위생 및 안전과 밀접한 관련이 있으며, 지하공간정보를 정밀하게 구축하여 시설물의 유지 관리, 안전, 지하 공간 개발 등에 주요한 정보로 사용하고 있다. 본 연구는 국내에서 구축되어 현장에서 활용되고 있는 지하공간정보의 신뢰도를 증대하여 현장 활용성을 증대하기 위한 방안을 연구하였다. 이를 위하여 국내의 지하공간정보 관련 구축 현황을 정리하고, 공간정보 선진국인 미국, 영국, 캐나다, 프랑스, 호주 등에서 적용되고 있는 지하공간정보 품질등급제의 사례를 조사하였다. 현장 활용성 측면에서 국내의 관련 분야에서 종사하는 현장 전문가 및 수요자의 지하공간정보 관련 제도 및 기준, 관리 방안 등에 대한 설문을 진행하고, 통계 분석을 실시하여 도입에 따른 연관성을 분석하였다. 본 연구를 통하여 지하공간정보의 구축 방법, 정확도 및 신뢰도 등에 따른 품질 등급제의 도입이 필요하며 관련 제도 및 규정 등의 정비가 필요하다는 결론을 도출하였다.
