  • 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.

  • 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.

  • As part of an effort to leap smart cadastre system by doing rearrangement of various mismatches in the land register, the cadastre renovation project is being recently conducted. In response to this demand, this paper proposes an image-based rapid parcel boundary demarcation plan using the high resolution aerial image with a GSD (Ground Sample Distance) of 5cm that matches to real ground boundary situation in residential area. To review the feasibility and accuracy of this proposed methodology, we compared the accuracy of parcel boundary point and parcel area extracted from the digital stereo plotting on the basis of results of cadastral boundary surveying and land register over the selected two test areas. The comparative accuracy result of all boundary points by digital stereo plotting is satisfied with accuracy requirement according to the criteria of the enforcement regulation of cadastral surveying, whereas it exceeded allowable error of ${\pm}0.07m$, more strictly specified in the Special Act on Cadastral Renovation. And about 20% of the total 70 parcels extracted by digital plotting are out of area tolerance in Jecheon study area, and 10% of the total 19 parcels in Suwon study area. The parcels exceeding accuracy limit are mostly due to the occlusion caused by building roof or eaves, and the obstacles such as trees existing on the boundary. Furthermore, an object identification is impossible in image because of vague boundary reference in case of nonexistence of man-made structures or natural features. Therefore, the utilization of boundary identification stickers is recommended as a solution for these types of land parcel.

  • Cadastral map information is created by registering parcel information such as location, lot number, land category and boundary through the cadastral survey. However, with regard to boundary point coordinate, computerized cadastral information data was registered to either two decimal places (unit in centimeter) or three decimal places (unit in millimeter) so that a confusion in cadastral administration and cadastral survey has been caused. Therefore, the purpose of this study is to look for a method of matching two different coordinate systems through the consideration of registration of cadastral information data and area calculation. In conclusion, the result of the investigation not only shows that areal change and the creation of minute polygons resulted from land alteration could be solved by changing boundary point coordinate from two decimal places to three decimal places, but also suggests that the related laws and regulations to register boundary point coordinate to three decimal places should be institutionally corrected and applied.

  • Because a map consists of many lines, a process of recognizing an object in a map is one to group lines that are consistent with the structure of the object. Therefore, it is important to establish an efficient method for finding lines which constitute objects. In this paper, a novel method for recognizing roads and districts in a land register map is proposed. In this method, lines that constitute objects are searched in a reduced search space by defining some relations between lines, and objects are recognized by using the structural information of the objects. As a result, the search space is reduced effetively, and even objects that embody the broken lines and the crossed lines are recognized.

  • This study examines and analyzes residential environment and factors with partial region of Chungjang-dong, Dong-gu, Gwangju based on land register and questionnaire. Consequently, most of residents are in their forties or over and working at downtown or place near it. It is found that rate of their own house is high and they live in the current house over 10 years. Residential factors at downtown area include its convenience, distance to workplace, convenient transportation and easy use of cultural and commercial facilities, but their consciousness of residence shows a low satisfaction with children education, air pollution, noise, parking facilities, green zone for making community, resting place, sunshine, view and privacy.

  • As the injunctive effect on the real estate gets announced in public once the seizure register gets exercised in terms of auction and the action of disposal by the real estate owner afterwards becomes nullified in the relationship with a seizure creditor or a successful bidder, the register performed by the cause of disposal action that cannot confront with the seizure or provisional seizure, becomes cancelled in virtue of a registration officer's office. Accordingly, in case of being a singular successor who relatively loses property in a relationship toward the successful bidder due to the injunctive effect of provisional seizure, the identity with building owner and land owner as the precondition of establishing legal superficies according to the custom must be decided based on the time of provisional seizure. The Supreme Court Decision 2010Da52140 delivered on October 18, 2012 has great significance from the fact that it has settled inconsistency in existing precedent cases with such purpose.

  • In Korea, Switzerland has been known as a country that integrates the Cadastral System (hereafter as CS.) and the registration system(hereafter as RS.) according to a research report by the Ministry of Home Affairs since 1975. However, I found that Switzerland's CS. and RS. were separately managed by the Dept. of Defense, Civil Protection & Sports(hereafter as DDPS.) and the Dept. of Justice & Police(hereafter as DJP.). Therefore, I have a question about where is the institution in charge of the CS. and RS. in Switzerland, what are the relevant laws and regulations, and what are the related public records, and the background and purpose of this study is to resolve this. Research Results First, cadastral affairs are handled by the Cadastral Surveying Division at the Federal Office for Topography (Swisstopo) under the DDPS, and the registered affairs are handled by the Private Law Division at the Federal Office for Justice under the DJP. Second, Cadastral-related laws include 'VAV' and 'TVAV' newly enacted in 1993, and Registration-related laws include 'Civil Act(ZGB)' and 'Order on Land Registration(GbVO)' etc. which have been in effect since 1912. Third, the cadastral record includes the Cadastral Books, Cadastral Maps & Numerical Cadastral Books etc, and the register includes the Hauptbuch, Tagebuch, Pläne, Liegenschaftsbeschreibung etc. It is hoped that the results of this study will provide an accurate understanding of the fact that Switzerland's CS. is managed separately by the DDPS, and the RS. is managed by the DJP.

  • The introduction of the world geodetic reference system in cadastral sector can apply the international standardization of cadastral survey and can be the basis for the creation of new industries by merging with other industries based on spatial information. With the introduction of the world geodetic reference system, non-coincidence land may cause problems which are whether the cadastral record and the real estate register are not consistent, etc. This problem infringes on the protection of ownership of citizens suggested in the main purpose of 「Act On The Establishment, Management, Etc. Of Spatial Data」. We have analyzed at overlapping cases between private land and overlapping cases between national and public land and suggested institutional improvement measures to solve problems arising on the site. As a result, it will be necessary to introduce a transformation verification measure by the world geodetic reference system in order to assign a function as a cadastral records to mapping converted to the world geodetic reference system. It is also expected that the legal and institutional basis should be established for alert adjustment and positioning through verification measures. Finally, it is difficult to determine the transformation factor as the co-ordinates of common points also differ because survey results vary by work area. Therefore, it is deemed necessary to consider the requirement to use the cadastral measurement basis by the world geodetic reference system in 2021.
