Improvement of the Korean LADM country profile to build a 3D cadastre model

In this study, a 3D land administration model is proposed using a cadastral resurvey form, including the representation of 3D physical properties and 3D rights. The new 3D cadastre model can contain underground utility and superficies information to present the physical and legal information on both buildings and underground features. The shape of land units and terrain, and azimuth are also included as secondary information on features in this new model. Thus, the proposed 3D new version of the Korean country profile of the Land Administration Domain Model would be the next generation land administration model in Korea to represent all types of Cadastre information.
