A Review of Korean LADM Based on the Cadastre Reform Project

In modern society, many efforts in land management are tried to make an effective land management model over the world. As a remarkable outcome on ISO/TC211 WG7, international cooperation finally standardized the LADM (Land Administration Domain Model) in order to implement the land administration system and the land information efficiently. It also includes the standard of administrations, laws, spatial elements and surveying related with land. In 2012, a Korean land administration model (Korea country profile) proposed to the ISO/TC211. But there are limitations to express 3D spatial information, physical objects and rights because proposed model was only demarcated 2D physical information. Therefore, in this study, 3D components such as 3D parcel, 3D right property and 3D physical property information are added to the proposed Korean LADM last year. This new proposed model contains the 3D physical attributes information about buildings, which will be more materialized ‘Administrative Package’ components illustrated in the Korea country profile last year. In addition, the cadastral reform project has been performing to correct cadastral information since 2012. This project suggests that the new cadastral model which contains underground utility and superficies information should be basically registered to present physical and legal information in parcel information. The shape of land, terrain and azimuth information are also provided as secondary information in this cadastral model. Thus, government expects that it will be a next generation land administration model which is able to cover all kinds of information on cadastre. Nowadays the 3D cadastre is becoming essential elementary to maintain land administration as a world trends. Nevertheless, till now the 3D cadastre is applied and implemented only several megacities in Korea. Cadastral reform project has been carried out as a national project. The new proposed model is needed and applied to other cities. Finally, we suggested updating proposed Korean
