The cadastral system provides land ownership information by registering and representing land boundaries on a map. The current cadastral system in Korea, however, focuses mainly on the management of 2D land-surface boundaries. It is not yet possible to provide efficient or reliable land administration, as this 2D system cannot support or manage land information on 3D properties (including architectures and civil infrastructures) for both above-ground and underground facilities. A geometrical model of the 3D parcel, therefore, is required for registration of 3D properties. This paper, considering the role of the cadastral system, proposes a framework for a 3D underground cadastral system that can register various types of 3D underground properties using indoor mapping for as-built Building Information Modeling (BIM). The implementation consists of four phases: (1) geometric modeling of a real underground infrastructure using terrestrial laser scanning data; (2) implementation of as-built BIM based on geometric modeling results; (3) accuracy assessment for created as-built BIM using reference points acquired by total station; and (4) creation of three types of 3D underground cadastral map to represent underground properties. The experimental results, based on indoor mapping for as-built BIM, show that the proposed framework for a 3D underground cadastral system is able to register the rights, responsibilities, and restrictions corresponding to the 3D underground properties. In this way, clearly identifying the underground physical situation enables more reliable and effective decision-making in all aspects of the national land administration system.
地籍系统通过在地图上登记和表示土地边界来提供土地所有权信息。然而，韩国目前的地籍系统主要侧重于二维土地表面边界的管理。由于这种二维系统无法支持或管理地上和地下设施的三维属性（包括建筑物和土木基础设施）的土地信息，因此尚无法提供高效或可靠的土地管理。因此，需要三维地块的几何模型来登记三维属性。本文考虑到地籍系统的作用，提出了一种三维地下地籍系统框架，该框架可以使用竣工建筑信息模型（BIM）的室内测绘来登记各种类型的三维地下属性。实施包括四个阶段：（1）使用地面激光扫描数据对真实地下基础设施进行几何建模；（2）基于几何建模结果实施竣工BIM；（3）使用全站仪获取的参考点对创建的竣工BIM进行精度评估；（4）创建三种类型的三维地下地籍图以表示地下属性。基于竣工BIM室内测绘的实验结果表明，所提出的三维地下地籍系统框架能够登记与三维地下属性相对应的权利、责任和限制。通过这种方式，清晰识别地下物理状况能够在国家土地管理系统的各个方面实现更可靠、有效的决策。
