  • To manage national territory and cadastral data efficiently, accuracy and cost-efficiency in cadastral boundary surveying is inevitable. The efficient management of cadastral data is a very important element in national land management. Survey techniques are being introduced. Recently, improvements in survey techniques have been made with the development of satellite surveying, Allowing accurate and fast surveys. If we can calculate the output accurately in real-time in survey fields, it will open a new method in cadastral detail surveying. According to the classification on Law of cadastral surveying, Cadastral surveying can be divided into cadastral control point surveying and cadastral detail surveying. The control point survey can be divided into cadastral triangulation surveying and cadastral traverse surveying. The detailed survey is usually perform by plane surveying. Among these, cadastral detail surveying will be reviewed in this study. In this study, the combination of the satellites, such as US managed GPS and Russian managed GLONASS was used. In the satellite survey in downtown, data interruption symptoms arose(according to the mask angle of the satellite). Therefore; we combined the satellites to get date more accurately. A block of Haewoondae New City in Busan, Korea, which has Numerical Cadastral Law was selected as the sample area for this study. Block II and III are surrounded by high rise apartments. One side of Block I and IV is level ground and the other side is full of high rise apartments. Especially, Block II is surrounded by high rise apartment houses with 20 meters width. In the results of the study Block II did not satisfy the allowable precision, while Block I, II and IV satisfied the allowable precision of the enforcement regulations of Cadastral Law. Therefore, it is judged that the traditionally used Total Station method should be used for supplementary survey on Block II, in stead.

  • To solve the inconsistencies between realistic boundaries and the cadastral record boundaries, the cadastral resurvey project has been funded by a large budget since 2012 and executed over a long period of time until 2030. However, if the causes of inconsistencies are not analyzed and addressed, these inconsistencies could possibly reoccur. Even though the causes of inconsistencies can be defined in several aspects, including regulations, surveying methods, and management of cadastre maps or survey results, and so on, this study focuses on analyzing the inconsistency problems in the management of cadastre maps or survey results. In order to resolve the problems in inconsistencies between the cadastre maps and survey results, the study proposes to develop the cadastre data model based on LADM (Land Administration Domain Model) to manage the cadastre maps and survey results in better ways. In order to proposed the Cadastre Data Model, we analyzed the cadastre management system implemented in Korea and identified requirements to resolve the problems in inconsistencies, which are considered in the proposed data model as follows: 1) cadastral management system based on individual parcels, 2) synthesis of a realistic boundary and cadastral record boundary, 3) management of official and sharing reference data, 4) consistent management of survey results and parcel boundaries, 5) temporal managements of parcel boundaries. In the end, this study proposes a cadastral data model based on the LADM to integrate and manage the cadastral surveying results of the new cadastral management system.

  • The major purpose of the present study is to gauge the general applicability of cadastral surveying and LiDAR surveying. LiDAR survey is the method which obtains Geospatial information of the terrain. We will get a most topographic models at Digital Elevation Model(DEM) using LiDAR survey data. Also, we will consider both the surface parcel partition and volume parcel as a part of Geospatial relationship model. This study will focus on enhancing the efficiency and analysis of continual cadastral map and LiDAR DEM. I would like to close by proposing that LiDAR surveying will contribute in cadastral surveying.

  • Even though the data of digital cadastral map, stored in the Korea Land Information System(hereinafter referred to as "KLIS") has a wide variety of errors, it has been used in a cadastral surveying field without any compensating work. As a result, it has given rise to a lot of problems when we use this digital cadastral map in the cadastral surveying field. That is why we should analyse the accuracy of digital cadastral map which has been stored in the KLIS. In this context, this paper has been intended to provide acceptable proposals with regards to present operation of KLIS or the cadastral re-survey project in the future by analysing the data of digital cadastral map which is one of the layers of the KLIS. Our study results showed that the accuracy of both the location and area in the present KLIS datum was not satisfactory Therefore, in our own judgment, it is necessary to revise cadastral maps more accurately in order to use in the field of cadastral surveying or in carrying out the cadastral re-survey project.

  • Korean government has constructed a nationwide cadastral map database through the cadastral map computerization project and also produced a variety of spatial data through the NGIS (National Geographic Information Systems) project. Under this circumstance, it is needed to set up the new automatic methodology that effectively solve cadastral non-coincidence problems by using various digital map data instead of expensive field survey methods. This study proposed a new automatic methodology for cadastral non-coincidence surveying and developed a prototype system as a proof of concept. Validation of this proposed method was done with some test areas. Results showed that this methodology could easily detect and assess both regional non-coincidence levels and cadastral map quadrangle non-coincidence levels. We expect that this new methodology can provide many benefits in planning and determining work priority of the forthcoming nationwide cadastral re-surveying project.

  • This study utilized the GPS data of the stations of triangulation of Changwon-si, Gyeongsangnam-do to conduct comprehensive analysis on tolerance level and regional characteristics. Based on this analysis, it was attempted to seek the method to derive more accurate result when further performing cadastral control point surveying for cadastral detail surveying. For the stations of triangulation installed at time of the land survey project, the study result showed that the most results of the stations of triangulation are stable if they were not moved naturally or artificially by themselves. Therefore, it was concluded that the stations of triangulation installed at the time of the land survey project should be preemptively selected for use of the given points when making decision of result of cadastral control point surveying. In addition, if the result of the cadastral control point surveying is made decision based on the stations of triangulation presented as the stable result in this study result, it seems that the same surveying result will be maintained and managed at all time, even if they are going to be further reinstalled due to loss of them.

  • In the numerical cadastral surveying field, the cadastral surveying would be measured with the Total Station surveying (electronic plane table surveying) system that consist the Total Station for surveying and the computing system for recording and editing the measured coordinates data by the TS. This study would suggest the advanced method, which is used on the RTK-GPS instead of TS for surveying and the computing system for handling the coordinates data and mapping. As a result of this study, although the measurement accuracy of the RTK-GPS and TS surveying make no greate difference, the suggested method reduces the cost of time and work force with the TS surveying. Besides, the new survey method would be more efficient due to directly handling the data and mapping in the field.
