The existing 2D cadastre as the core engine of land administration systems met with the difficulty of managing and representing the real 3D world. As a result, a 3D cadastre system has emerged as a solution oriented towards managing, representing and providing 3D spatial information related to physical status, land rights, restrictions and responsibilities. The aim of this study is to establish the foundation of the 3D cadastre information system. With this in mind, this paper aims not only to set up the data range of the 3D cadastre, but also to design a conceptual model based on an LADM (Land Administration Domain Model) through the investigation of legal restrictions and land uses relating to spaces in 3D.

Due to the increasing demands on the efficient use of land and the fast growth of construction technologies, human living space is expanded from on the surface to above and under the surface. By recognizing that the current cadastre system based on 2D was not appropriate to reflect the trend, the researchers are interested in a 3D cadastre. This paper proposed the 3D cadastre data model that is appropriate to protect ownership effectively in Korea. The 3D cadastre data model consists of a 3D cadastre feature model and a 3D cadastre geometry model, and the data are produced by a 3D cadastre data structure. A 3D cadastre feature model is based on 3D rights and features derived from case studies. A 3D cadastre geometry model based on ISO19107 Spatial Schema is modified to be good for 3D cadastre in Korea. A 3D cadastre data structure consists of point, line, polygon and solid primitives. This study finally purposes 1) serving and managing land information effectively, 2) creating rights and displaying ranges about infrastructures above and under surface, 3) serving ubiquitous-based geoinformation, 4) adapting ubiquitous-based GIS to urban development, and 5) regulating relationships between rights of land and registration and management systems.

The cadastral system of our country is same as Japanese 2D-cadastral system. Recently, not only surface but ground and underground is became the developable space, so today the management of cadastre becomes more difficult to preserve each ownership of properties and to manage the nation lade efficiently. Consequently, we are in need of the 3D-cadastral information system for handle with whole cadastre information. In this paper, we propose the efficiently registrating strategies and more stabile construction technique for the 3D-cadastral information system.

3D cadaster problems are getting attention and studied increasingly. However, correct concepts have not been established for three dimensional land uses and different rights problems around them. This is primarily due to the lack of proper methods for implementation and operation of 3D cadaster. 3D cadaster requiring far more huge data than 2D should be built in DBMS and need appropriate methods and processes for this. This study propose a method to model 3D cadaster using DBMS. First, it analyse and visualize possible problems around divided superficies in 3D spaces. Based on this, it illustrates UML models and shows an O-R mapping process to implement them using a RDBMS.

The usage of the land is enlarged with above-surface space and sub-surface space as well as surface, as the concern about the land use is increased because there are many factors like the recent development of the science technique, Rapid increase of the population, Rapid city's diffusion, industrialization. According to the cubicalness of the land usage such as these, We have the limit to register the right-objects in space like various buildings and facilities by present registration method of 2D cadastre registration because of 2D registration object. Thus, it is necessary for plan to register an ownership, other privilege relations and the physical objects like various buildings and facilities established on both surface and space. There are two steps in this study. First step is the necessity of 3D cadastre registration and object analysis of cadastre registration, second step is 3D cadastre division and its visualization. Finally, this study will present the realizable model for a 3D cadastre registration.

The 3D printing technology which is called new revolution of 21C is under the spotlight recently. The technology takes effects on general manufacturing industries, as well as the prototypes, education, health care, construction. and other industries. It seems that personalized products will be produced and distributed with the introduction of 3D printers. In the case the possibility of violating intellectual property rights, we propose a system that can prevent the violation.

The uses of land were relatively simple in the old days, but they are being expanded rapidly to the aboveground and underground due to the urban concentration, the large-scale urban development and so on in these days. Accordingly, the concept of the rights to lands grows from 2D to 3D, and many studies about the 3D cadastral information have been performed in recent years. Several studies were performed about the construction and the visualization of the 3D cadastral information, but most of them focused on the 3D visualization of the buildings and facilities. However, it is more desirable to visualize the individual objects of the rights to lands while considering 'the information on the rights' as well as the 'physical information'. Therefore it is supposed to construct and use the 3D cadastral information based on the individual objects of the rights in this paper. The level of the cadastral information will be upgraded by making and describing more detailed 3D cadastral information through this paper. And also the applicability of the 3D cadastral information will be improved when it is used with the real estate information, the demographic information and many others.

In this paper, we suggested plan that utilize the mobile mapping system data for constructing 3D cadastral information of roads and buildings effectively. 3D cadastral information means conflation of existing cadastral information and spatial information. It also means 3D land management that can register and manage various spatial information with land information effectively. Technically, geometry information and attribute information by image or radar scanner and location information of geographic features calculated by GPS/INS integration technology are useful for constructing 3D cadastral information included in buildings and features on the ground. As a result, the application of mobile mapping system for constructing 3D cadastral information will make a scientification and enhancing of the land information.

Recently, in a field of cadastre, a computerization of cadastral map is in progress with great growth of GSIS field. Also, the needs fer the integration of land and building information are widely increasing for integral-management and its application of various land related information. Through a revision of cadastral laws to replace the existing 2D-Cadastre with the 3D-Cadastre, a legal basis to register the position of buildings and facilities is prepared in the governmental or civil fields. This paper presented 3D-Cadastre theory that has been studied on Europe and surveyed building position directly with Totalstation at cadastral control point after choosing pilot test area, Also, the most efficient surveying method of registering building in a cadastral map is presented with comparing and analyzing building position after surveying digital orthophoto and digital map. And it is constructed a 3D information cadastral map model that can make the integral management of land, building, connecting land recorders, building management ledgers, building titles, building pictures, and related attribute information.

When cadastre system was first introduced in Korea, we only uses the surface of the land and thus its form was very simple. Nowadays on account of the development of architectural technology, the rapid expansion of population and urbanization, the cubic utilization of land including the land usage of underground and surface space is widely settled. This article studies the function of cadastre and public notice to encourage cubic utilization of the land, argues the necessity of 3D-cadastre system to protect property right, and suggests the GPS land measurement as a possible measure.
