  • The value of Jeju Batdam has been reexamined as it is listed as a nationally important agricultural heritage and globally important agricultural heritage systems. However, it is already exposed to threats such as reduction of agricultural population and cultivation area. Despite efforts like the agricultural heritage system to preserve traditional agriculture, there is few basic investigation into the current status of Jeju Batdam. The purpose of this study is to estimate the length of Jeju Batdam. We used the continuous cadastral map of Jeju area to extract the boundaries of the field lot. In the cadastral map, the farmland was selected by selecting dry fields, paddy fields and orchards. 300 sample site were selected from the extracted farmland, and the boundaries between the Internet map and the parcels were superimposed and the differences were confirmed on the drawing. After that, field survey was conducted to confirm the boundary of the parcels and the existence of actual Batdam. It is estimated that the length estimated from this study is at least 23,983km and maximum 142,353km, which is at least 1,830km longer than 22,108km announced in 2007. Since Jeju Batdam is based on land parcel boundary, it is an objective and efficient method to utilize intellectual information. In addition, because it is subordinate to farmland, new information can be extracted reflecting the change of land use and make the spatial database based on the cadastral maps.

  • The objective of this study is to improve the survey rate and reliability of survey control point marks, which serve as the foundation for location-based services. Within the scope of this research, we have inspected the current status and reporting systems for national control point marks, public control point marks, and cadastral control point marks, identifying various issues. To tackle these challenges, we have prepared proposals for new unit cost calculations for national control point mark inspections, enhancements to the inspection and reporting systems for survey control point marks, and preliminary reporting procedures for surveyors using these control point marks. Additionally, we have established a workflow to refine the process of survey control point mark inspections and have proposed an automated system for calculating the unit cost for unreported targets. The study anticipates that these changes will improve the efficiency of future survey control point mark inspection tasks.

  • This paper, at first, intends to develop a conceptual model of spatial information eco-system based on the related literature reviews. The basic requirements in constructing the model are also specified. Next, the functional roles and interrelationships among the actors constituting the eco-system are analyzed to investigate the major reasons of inefficient and unsmooth flows of value-added process of Korean spatial information industry. Especially, the Korea Cadastral Survery Corp.(KCSC), which has dual organizational characteristics of public and private entity, is analyzed to be positioned as the most dominant actors in the eco-system. However, the KCSC needs to be changed and challenged to re-establish the missions and institutional roles for upcoming network societies. Here, we proposed 4 future-oriented development strategies and action plans to promote the Korean spatial information industry and to activate the eco-system.

  • The work establishing effective development and conservation plan and identifying current usage of national territory is an important task of the nation. In spite of the investigation being executed by law up to about 60 different, collecting information, method and time are different between them, so it causes duplication of the budget and policy confusion. And land use listed in the cadastral book officially represents the status of land use, but it is not easy to change according to current use. Therefore collection and information in a consistent manner is necessary to build up. In this study, for the national territory including public waters and underground space, we would like to analyse current land use information collection method and suggest system construction, legal system improvement and information utilization strategies. For the accurate and consistent land management, as a result, 3 dimensional land(include underground, public water and sea etc.) use status inspection and information management is needed. And the new act should be enacted and exclusive organization also be designated.

  • Trilateral adjustment can complement the problem of transforming cadastral maps into World Geodetic Coordinate system. First, it is possible to determine adjusted coordinate of common points that match each other over a wide area. Second, calculations that focus on specific points can be performed. Third, a solution that maintains the shape of the regional network can be obtained through constraints. Thus, the point coordinates can be determined appropriately for the survey system. In addition, heterogeneous survey results that span regions with different coordinate origins can be calculated on a single origin coordinate. This improves the efficiency of the workflow in tranforming cadastral maps into World Geodetic Coordinate System.

  • The network RTK surveying has been widely used in the field of cadastral surveys in recent years, and its use is gradually expanding. As a result of the implementation of GPS static surveys by civilian companies in accordance with the progress of the cadastral surveys and gradual civilian transfer plans and cadastral surveys, there has been an increase in the number of civilian companies performing surveys. In this paper, we describe the process of applying the results of analysis of conformity using the network RTK site calibration function on the local coordinate system to the GPS static surveying of the cadastral reference points in Anyang city. In addition, the measurement results of the network RTK site calibration function and the results of the GPS static surveying network reconciliation in the local coordinate system were compared, and the performance was determined within 0.04m maximum of RMSE(Root Mean Square Error), and further study on the application method is needed.

  • Aerial imagery, Satellite imaging and Hyperspectral imaging(HSI) are widely using at mapping those of agriculture, woodland, waters shoreline, and land cover, but are rarely applied at the Cadastre. There are many study cases on the overlay of aerial imagery and satellite imaging with Cadastral Map and the upgrade and registration of Cadastre' Land Category, however, reported as successful. Therefore, this study has been aimed to show the use of the Hyperspectral Imaging technology for Cadastre, especially for the land category. Also, the HSI sensor could function as a geospatial acquisition tool for error checks of the existed land categories, and as a helpful tool for acquiring the attributes and spatial data, such as the agriculture, soil, and vegetation, etc. This result indicates that HSI sensor can implement the Multipurpse Cadastre(MPC) by fusing with the cadastral information.

  • As In spite of a close relationship between the land and the building administration, the registration information have been managed separately, because of the different department and the different working area as a national office. To record and manage the exact location of the building within the land we should oblige to submit a status survey results and also register them on the cadastral map. Even now we should make a business cooperation system by building a co-construction of information. The purposes of this study are to suggest ways to improve the legal system for the exact registration of a building on the cadastral map and to look for ways to increase the confidence of building information by reducing the inconvenience of the people through the analysis of a current building administration.

  • According to the Korean Statistical Information Service(2019), the number of public land in Korea is 10,734,439parcels and 33,395㎢, accounting for 33.2% of the land area. In the meantime, the central government and local governments have been promoting the efficiency of public land management through annexation, but if the scale of cadastral record is different or the public land is registered in different types of cadastral maps, it is impossible to annexation and it is a major obstacle to the efficiency of public land management. As a way to solve these problems, the annexation method accompanied by survey was presented and the effect was analyzed. As a result, the number of parcels to be managed decreased by 91.7% and 99.6% of the actual survey cost was reduced despite the expenditure of only 54.9% of the existing method. It was found that the annexation survey of the public land, which are clustered by connection, can ultimately contribute to the efficiency of the public land management by newly establishing the indication of the public land. In the future, we hope that follow-up research on the public land management based on cadastral surveys will be conducted in various and in-depth ways.
