공공데이터 기반 디지털트윈 프레임 DB 구축 방안

Abstract

Digital twin, which is becoming increasingly important, depends on how high precision spatial information and attribute information are constructed on the real world in the future. However, if you look at the case in which 3D Land Geospatial Information construction failed to pass the preliminary feasibility test earlier, it is very important to build a digital twin and rationalize the cost of updating it. In this study, a method of constructing the frame DB, which is the basis of the digital twin, was studied using an appropriate DB among the previously constructed spatial information as the source data. Buildings are constructed by supplementing the Korea Address Information System and Building Life Cycle Management System data based on GIS Based Integrated Building Information. Roads are built by supplementing the High Definition Road Map, Road Register Database, and Korea Address Information System based on the National Base Map. Parcel was found to be able to construct a digital twin frame DB that can be continuously updated if the land information base map is used. In addition, it was suggested that road name address-based linkage key development and cooperating partnership composition for quality assurance are necessary for systematic updating. The frame DB to be built through this will play a role as reference data for buildings, roads, and parcels that are increasing in necessity in our society, and it will reduce the national budget and enable various applications.
