디지털 국토정보 구축을 위한 공간정보-건설정보 연계 기술 도출에 관한 연구: 건설정보·공간정보 전문가 집단을 중심으로

다국어 초록 (Multilingual Abstract)

In alignment with the expansion of spatial information utilization during the era of the Fourth Industrial Revolution, this study has explored the derivation of technologies for linking spatial and construction information to construct digital land information. Through theoretical considerations and a review of prior research, this paper examines the trends in technologies related to linking spatial-construction information, specifically focusing on techniques for assigning geolocation and the linking and transformation of shape and attribute information. Based on this, a survey was conducted among expert groups to derive the general requirements for linking technologies. In terms of developing geolocation technology, it was determined that there is a need to explore: based on IFC-GIS polygonbased georeferencing technology, identifing the geolocation level of IFC schema, exploring the corresponding map model for accurate geolocation input, and developing polygon extraction and matching point extraction technology, in addition to technology to convert IFC files with extracted geolocation values. Additionally, in the development of technologies for linking and transforming shape data and attribute information, it was concluded that there is a significant need for IFC file format conversion technology and attribute information verification technology based on the GLB format. This research presented the direction for linking spatial-construction information technologies that can be utilized in building digital land information. The results of the research are expected to contribute to future construction and utilization of digital national land information.
