본 연구에서는 토지에 관한 각종 정보 중 현재 2차원에 국한된 지적정보를 지적공부에 등록하고 있으나 토지의 입체적인 활용의 증대 및 이에 따른 입체적 권리의 다양화 등으로 2차원적인 토지정보의 등록방법으로는 효율적인 토지관리 및 소유권 보호에 한계에 이르고 있어 이에 대한 대안으로 3차원 지적정보를 지적공부에 등록할 수 있는 기본방안을 제시하고자 하였다. 이를 통해 국토개발에 대한 정책결정 정보를 효율적으로 제공 할 수 있으며, 국민소득의 증가에 따라 사회간접시설(SOC)분야 및 국민 개개인의 토지이용에 있어 각종 계획과 설계 등의 인프라 조성에 기여하게 될 것이다.

In recent years, due to the continuous density and urbanization of space, the expansion of awareness of rights, the need for landscape conservation, and the development of construction technology, the conventional flat land use has been deviated from the conventional flat land use, and the transmission line, urban railway, parking lot, communal district, underground shopping mall, pipeline, etc. Although 3D spatial activities are carried out in the form of 3D space, there are considerable difficulties in administration to manage the 3D use of land due to the inadequacy of related regulations. In this background, for the administration that can manage Sectional Superficies, which is a representative case of 3D spatial use of parcels, which is a registered unit of land, first, the law on the establishment and management of spatial information, and cadastral re-examination from the legal and institutional aspects Standardization of 3D space registration through amendments to the Special Act, etc. and the formation of consensus among related departments. Second, in technical and administrative aspects, the registration of Sectional Superficies based on cadastral survey results, establishment of a platform for integrated management of location and attribute data, and registration method was found to be in need of improvement. As suggested in this study, by registering and managing Sectional Superficies, it is possible to manage various 3D land use of not only ground space or surface space but also underground space. It is expected to be able to register and manage lot-based 3D land use efficiently.

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.

The existing cadastral record cannot meet various and changing demands on land information, improve user convenience, and raise administrative efficiency. In addition, three-dimensional parcels, or spatial objects about three-dimensional space cannot be registered in the conventional cadastral record. The limitation of cadastral information based on two dimensions is quite stressing the necessity of three-dimensional cadastral record. The purpose of this study is to develop new limns of cadastral record model in order. In register three-dimensional positions and right relations of land and buildings. This study examined land cases where space was being three-dimensionally used. As the result, cadastral record models both separated by steps and integrated were developed, which can contain matters of land, buildings, and right registration about three-dimensional land parcels. Also, this study suggested a method where a building can be separately registered according to it's the superficies division.

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.

지적제도를 관리하고 있는 대부분의 유럽 국가들은 한정된 토지의 지속적인 개발과 다양화 ㆍ입체화되어 가는 토지이용을 현 상태 그대로 표현할 수 있고, 입체적 토지이용으로 인하여 복잡하게 된 토지소유권을 체계적으로 등록 및 관리할 수 있는 삼차원 지적에 대한 연구 및 프로젝트가 활발히 진행 중에 있으며, 국제측량사연맹(FIG)에서도 지속적인 관심과 학술대회를 지원하고 있다. 또한 최근 국내에서도 이에 대한 관심이 증대됨에 따라 삼차원 지적도입을 위하여 지적법 전문개정을 통하여 건물 및 시설물 등의 위치(현황도)를 등록할 수 있는 법적근거를 마련하였다. 아울러 대한주택공사와 대한지적공사는 용인시 신갈읍을 대상으로 삼차원 지적정보관리 구축 시험사업을 추진중에 있다. 따라서 본 논문에서는 삼차원 지적의 개념을 이론적 배경으로 삼차원 지적의 국외 연구동향을 분석하고 국내 관련 현황을 토대로 삼차원 지적 모형을 개발하는데 목적이 있다.

Recently, a generation of high quality mosaic images from video sequences has been attempted by a variety of investigations. Among the matter of investigation, in this paper, generation on stereo mosaic utilizing airborne-video sequence images is focused upon. The stereo mosaic is made by creating left and right mosaic which are fabricated by front and rear slices having different viewing angle in consecutive video frames. For making the stereo mosaic, motion parameters which are able to define geometric relationship between consecutive video frames are determined. For determining motion parameters, affine model which is able to explain relative motion parameters is applied by this paper. The mosaicing method using relative motion parameters is called by free mosaic. The free mosaic proposed in this paper consists of 4 step processes: image registration with reference to first frame using affine model, front and rear slicing, stitching line definition and image mosaicing. As the result of experiment, the left and right mosaic image, anaglyphic image for stereo mosaic images are showed and analyzed y-parallax for checking accuracy.

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.

For constructing 3D information using aerial photograph or video sequences, left and right stereo images having different viewing angle should be prepared in overlapping area. In video sequences, left and right stereo images would be generated by mosaicing left and right slice images extracted in consecutive video sequences. Therefore, this paper is focused on generating left and right stereo mosaic images that are able to construct 3D information and video sequences could be made for the best use. In the stereo mosaic generation, motion parameters between video sequences should be firstly determined. In this paper, to determine motion parameters, free mosaic method using geometric relationship, such as relative orientation parameters, between consecutive frame images without GPS/INS geo-data have applied. After determining the motion parameters, the mosaic image have generated by 4 step processes: image registration, image slicing, determining on stitching line, and 3D image mosaicking. As the result of experiment, generated stereo mosaic image and analyzed result of x, y-parallax have showed.

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.
