  • The purpose of this study is to analyze the current status of expected cadastral coordinate maps by type of district boundary surveying and the problems of non-coincidence with the surrounding land parcels, and to suggest ways to improve them in the future. Currently, the expected cadastral coordinate maps are drawn using various methods such as reference point adjust adjustment, reference point adjust adjustment and present condition, reference point and present condition. As a result, there was a problem of non-coincidence such as overlapping or blanking in expected cadastral coordinate maps for cadastral confirmation surveying and surrounding individual parcels. In addition, detailed unified standards for minimizing the occurrence of non-coincidence problems are lacking. In order to improve the problems analyzed, the study suggested the acquisition and management of digital coordinates for the parcels around the district boundary, the preparation and dissemination of cadastral surveying results determination standard manual for the preparation of expected cadastral coordinate maps, and the preparation of educational programs for cadastral surveying results determination.

  • 우리나라는 지난 반세기 동안 6ㆍ25전쟁과 무분별한 국토의 개발로 인하여 문화재가 많이 파괴되고 유실되는 피해를 입어왔다. 한번 손실된 문화재는 기존 데이터 없이는 완전복구가 어려운 실정이지만, 이러한 문화재의 복원을 위해서 오늘날 아직도 일제시대의 지적도를 아무런 검증 없이 사용하고 있는 것이 현실이다. 또, 일제시대 지적측량의 기술상의 착오, 지적도면의 신축에 따른 오차를 무시하고 고분의 복원작업에 그대로 사용하고 있다. 따라서, 본 연구에서는 TS를 이용하여 일제시대의 지적도와 현재의 현황측량을 바탕으로, 일제시대의 지적도가 오늘날에 와서 고분들을 복원할 때 얼마나 이용가치가 있는지 판단 할 수 있는 토대를 만들기 위함이고, 또 과거와 현재의 자료를 비교 분석함으로써 역사적 사실을 알 수 있는 기초 자료기반을 구축하는데 있다.

  • While images and aerial photographs using conventional satellites have the advantage of providing data in a vast area, there is a difficult aspect: the limitations of filming and processing data in a particular region at a desired time and the repetitive filming of a short cycle. With the development of many new technologies to overcome these shortcomings, methods of building cadastral information are changing rapidly. In particular, unmanned aerial vehicles that deploy cadastral information quickly and accurately using UAV have increased interest in technology that obtains cadastral information. Therefore, the purpose of this study was to suggest the application of cadastral measurement tasks in areas subject to cadastral measurement using UAV. To this end, the Commission decided to compare and analyze the accuracy of high-resolution images produced by observation area and apply them to existing cadastral work using verified images and cadastral data. In this study, we will analyze the applicability of UAVs to their cadastral survey by analyzing the current status of legislation related to cadastral survey and the technical characteristics of UAVs and propose technological, legal and institutional improvement measures for introduction based on them.

  • The case of a forest area has tome limitations of adopting a ground surveying like as TS (Total Station) and RTK-GPS (Real Time Kinematic-GPS) due to the specificity of the forest area. Therefore, the new method, is different from exist the cadastral re-surveying method in a metro area and a cropland, is applicably considered in the forest area. In this paper, we suggest the applicability of the digital cadastral map of forest which is used at KLIS. According to the result of study, the most important area error value for adopted in the cadastral re-surveying is almost contained the error tolerance. Therefore, KLIS data, if it is related with the actual reference data for adjusting the location boundary, is suitable to be adopted in the cadastral re-surveying.

  • Recently, as GIS industry has substantially grown up, convergence between industries such as the application coverage of surveying and cadastral information is gradually on the increase. The new approach of convergence between topographic surveying and cadastral survey is indispensable to make the change of geospatial environment ready and to maximize the utilization of National Spatial Data Infrastructure(NSDI). The purpose of this paper is to seek the way of synergistic improvement in topographic surveying and cadastral survey in comprehensive aspects of national geospatial information. First, we reviewed policy environment to clearly establish aim of convergence and promising perspective of GIS industry policy, considering NSDI. In addition, we examined current state of administration (organization, human resource, service) and institution situation. We came up with interior ability and external policy environment as well as critical success factor for the synergistic convergence by using SWOT analysis. Lastly, we developed basic perspective of convergence and improvement model and concrete scheme for stakeholder to complementary make progress. We can come to conclusion that the convergence of topographic surveying and cadastral survey should be not only carried in macro outline of successful NSDI but also committed to completion and maintenance of GIS framework.

  • 지적 측량분야에서의 위성영상의 활용사례는 거의 전무한 상태이며, 그 이유로는 여러 가지가 있겠으나, 무엇보다 위성영상의 해상도가 낮음이 가장 큰 이유라 할 수 있다. 하지만 저렴한 비용으로 넓은 지역을 단시간에 분석, 다양한 정보를 얻을 수 있는 큰 장점 등으로 인하여 앞으로의 그 활용가치는 매우 크다 할 수 있다. 본 연구에서는 IKONOS영상을 이용하여 지적재조사 측량에 적용 가능성을 알아보기 위해 실험한 결과 다음과 같은 연구성과를 얻었다. 먼저, 수치지적도와 IKONOS 영상을 중첩하여 도심지의 건물들을 검사점으로 오차를 측정한 결과 X방향으로 평균 2.77m, Y방향으로 평균 1.58m가 발생하였고 본 연구에서 활용한 영상이 나타내는 면적을 기준으로 개략적인 비용을 산출해 본 결과 위성영상 $6km{\times}5km$의 소요비용이 260,117,000원 정도로 나타났고, 총 소요비용 중 영상의 재료비 비용이 상당히 낮게 차지한다는 장점이 있었다. 그리고 위성영상 기술은 앞으로 많은 발전이 있을 것으로 판단되어 정확도는 더욱더 향상될 것이다. 현재로서는 위성영상을 지적재조사 측량 방법으로 정립하기에는 한계가 있다고 본다. 다만, 지상측량 방법으로 측량이 곤란한 지역 즉, 접근이 제한되는 지역의 사전 정보 정보를 획득하는 수단이나 현황을 참고하는 수준정도로서는 충분한 활용 가능성이 있을 것으로 판단된다.

  • UAVs (Unmanned Aerial Vehicle) are generally classified into fixed-wing and rotary-wing type, and both have very different flight characteristics each other during photographing. These can greatly effect on the quality of images and their productions. In this paper, the change of the camera rotation angle at the moment of photographing was compared and analyzed by calculating orientation angles of each image taken by both types of payload. Study materials were acquired at an altitude of 130m and 260m with fixed-wing, and at an altitude of 130m with rotary-wing UAV over an agricultural land. In addition, an accuracy comparison of boundary surveying methods between UAV photogrammetry and terrestrial cadastral surveying was conducted in two parcels of the study area. The study results are summarized as follows. The differences at rotation angles of images acquired with between two types of UAVs at the same flight height of 130m were significantly very large. On the other hand, the distance errors of parcel boundary surveying were not significant between them, but almost the same, about within ${\pm}0.075m$ in RMSE (Root Mean Square Error). The accuracy of boundary surveying with a fixed-wing UAV at 260m altitude was quite variable, $0.099{\sim}0.136m$ in RMSE. In addition, the error of area extracted from UAV-orthoimages was less than 0.2% compared with the results of the cadastral survey in the same two parcels used for the boundary surveying, In conclusion, UAV photogrammetry can be highly utilized in the field of cadastral surveying.

  • The cadastral resurvey project has been planned for 19 years, from 2012 to 2030, which refers that now is at the beginning stage. The aim of a project was to correct the registration of cadastral register, which was not corresponding to the actual circumstances. As a national project, the government has been charged of this project to achieve the effective land management and protect the property rights of people, by changing analogue cadastral surveyed in 1910 to digital cadastral. On this paper, we focused on reinvestigating the principle of cadastral resurvey project and suggesting better solutions for problems, so as minimizing numbers of trials and errors in the project.
