정부에서는 사회 경제적으로 많은 문제를 발생시키고 있는 지적불부합지 문제를 해결하고자 지적재조사 사업을 계획하였으나 수 조원에 달할것으로 예상되는 막대한 사업비와 국민적인 이해부족으로 인하여 중단이 되었다. 이렇게 지적재조사 사업이 전면 중단된 상황에서 지적불부합을 효율적으로 해결하기 위해서는 현지 측량 방식에 기반하여 불부합지를 조사하고 정리하기보다는 현재 구축되어 있는 지적도 전산화 데이터와 GIS 관련 데이터 등을 최대한 활용하여 조사할 수 있는 새로운 방법론의 모색이 필요하다. 본 연구에서는 기 구축되어 있는 수치지적도와 수치지형도를 이용하여 지적불부합을 측정할 수 있는 방법론과 절차를 개발하였다. 그리고 모든 과정을 상용 GIS 소프트웨어를 이용하여 구현하였다. 방법론의 실험을 위해 실제 사례지역을 선정하여 적용하여본 결과 불부합을 정량적으로 조사하고 해석할 수 있는 가능성을 제시할 수 있었다.

A cadastral map that is base map on Land Information System is divided by two categories, graphical and digital cadastre. And digital cadastre can be displayed with location coordinates of nodes that depict parcel boundary on digital cadastral records. The transformation of digital cadastral records means that imported text data of node coordinate would be transformed into system data. This study was implemented to search reasons of errors resulted from transformation of graphic data and then to analyze the accuracy in terms of Position and area. For this, checking of software used in Geo-Spatial Information System was implemented at first and it was found that the accuracy is up by using double precision in coordinate transformation. On the position accuracy the errors at nodes was erased during making topology and the errors did not effect other nodes. On the area may the area errors because of being in error limit of allowable area had no problems in using of system.

In the land boundary surveying related to the real-estate problem, numerical cadastral surveying techniques are now widely required for the accuracy improvement. In this paper, the photogrammetric techniques in order to improve the accuracy of numerical cadastral surveying were investigated, Independent Model Triangulation, Bundle Adjustment, and Bundle Adjustment with additional parameters were compared and analyzed to propose the method for the more reliable and accurate results in numerical cadastral surveying.

Cadastral surveying is related to demarcating legal boundaries and areas for the sake of registering a properly on cadastral records or restoring registered boundaries on the ground. It is composed of control surveying (cadastral triangulation and supplementary control surveying) and detail surveying. Detail surveying is classified into plane table surveying by graphical cadastral map and numerical surveying by boundary point coordinates. In this study we compared the accuracy of plane table surveying with numerical surveying using Parcel Based Land Information System(PBLIS) data constructed by the cadastral map digitalization business. In conclusion the result by numerical surveying was analyzed as more accurate than the result of plane table surveying, as Root Mean Square Errors(RMSE) of graphical cadastral surveying is 0.766m and that of numerical cadastral surveying using Total Station(T/S) is 0.683m. Therefore, PBLIS data is expected to be used for surveying legal boundaries and areas in the near future.

In this study, from a long-term perspective, we tried to find and present a plan to apply the results of transformation of cadastral coordinates to the world geodetic system in stages for cadastral records of graphical and digital cadastral area. There was a case where the difference in area before and after the transformation occurred irregularly in the transformation result of the cadastral coordinate system currently being promoted. In addition, it was found that transformation errors in cadastral non-coincidence areas occurred accumulatively, and the period for acquiring world geodetic results for cadastral reference points was insufficient. In order to solve this problem, the study proposed a plan to provide spatial information and related fields through advancement of continuous cadastral maps, etc. for maps that have been primarily transformed by the end of 2020. In addition, the maps used for cadastral surveying purposes were presented in the direction of applying them to cadastral records in numerical form in the long term to conform to the characteristics of graphical and digital cadastral area. It is expected that more stable cadastral record will be reflected by applying the world coordinate transformation performance by dividing the graphical and digital cadastral area.

In order to manage the waterfront efficiently, we are to find the efficiency of producing method for digital orthophoto that presents natural form on lands and digital orthophoto cadastral map that presents the range of physical situation and property on lands in this study. Through this study, We can check that digital orthophoto cadastral maps for the boundary management of the waterfront are utilized widely at various field except the main purpose. Thus, we resolve the leading subjects that include the accuracy evaluation on produced maps and the bond edge of map sheet for the cadastral maps in order to drive activistic utilization and application.

Numerical cadastral surveying method has advantages of higher accuracy and less individual error than planetable surveying method if we consider the result of surveying at the same area. Now in the areas where they use numerical cadastral records, coordinate is the basis when the boundary location is registered in numerical cadastral re-cords or is reconstructed on land surface, and this coordinate represents simply the absolute locational relationship with respect to origin point. But when we register the cadastral boundary location in cadastral or reconstruct it on land, relative relationship with respect to traverse point is more advisable basis than absolute relationship with respect to orgin point. This study contributes to the numerical cadastral surveying by discussing the problems to be improved that the principle of coordinate based boundary location registration and reconstruction has.
