3차원 지적 구축을 위한 세밀도(LOD) 적용 방안 기초연구

Abstract

As the 3 dimensional land use to increase the land efficiency has been increasing, the present state of the land use should be managed and registered with consistence. This study adopts LOD (Level of Detail) concept defining 3 dimensional location·geometry information and texture to help 3D cadastre of 3D land use constructed with consistence. Two types of LOD, shape LOD (SLOD) and location LOD (LLOD), are suggested in the study. Interview with experts is done as well. As a result, the SLOD and the LLOD for physical registry objects are more suitable from SLOD 1 stage to SLOD 2 stage and from LLOD 3 stage to LLOD 4 stage respectively. While the SLOD and the LLOD for legal registry elements are more suitable from SLOD 1 to SLOD 2 and from LLOD 3 to LLOD 4 respctively.
