오늘날과 같이 산업사회의 급격한 발달로 인하여 토지의 재산적인 가치가 높게 평가되면서 국민들은 토지에 대한 정확하고 다양한 정보제공을 요구하고 있다. 그러나 우리나라는 토지조사사업으로 작성된 지적공부를 현재까지 사용하고 있으나 토지이동에 따른 지적경계의 변동과 지적도면이 변질되고, 신축과 훼손이 심해져서 지적도의 경계선과 지상경계선의 불일치로 토지분쟁을 유발하여 대국민관계에 불신을 초래하고 있는 것이 사실이다. 그러나 아직까지 정확한 해결방안을 찾지 못하고 있는 것이다. 그러므로 본 연구에서는 현행 지적공부의 문제점인 경계불부합을 효율적으로 정리할 수 있는 방안을 위해서 지상경계를 TS측량방법을 이용하여 필지별 면적과 경계점간 거리의 변화를 측정하여 도시지역과 농촌지역에 관한 도상 경계와 지상경계를 분석하여 문제점을 해결할 수 있는 방법으로 지상경계위주의 좌표로 등록하여 정리하는 것이 효율적인 방법임을 제시하였다.

The current cadastral surveying is used digital cadastral map. This map is no local confirmation. Besides, Base cadastral map drawn up 100 years ago. And Graphical cadastral characteristic is difficult to ground boundary points restoration. Due to the lack of ground boundary points can cause land dispute and Cadastral Non-Coincidence. In this Study, Understand the concept of accuracy and error, Analyzing the current regulations. Also Comparative analysis of current cadastral regulations and other surveying regulations to suggest improvements to the cadastral surveying. The results indicated a clear definition of accuracy and error and The installation of permanent ground boundary points are needed. Uniform and consistent reference point system is needed. In addition, the accuracy provided by the landowner should understand. Cadastral Surveying Regulations require specific and detailed procedures.

고해상도 컬러 위성 영상 촬영을 위한 다중분광 센서를 탑재한 위성의 영상은, 탑재체에 장착된 센서의 위치에 따라, 동일 지역에 대해 센서 간의 촬영시각의 차이가 발생한다. 만약 이동하는 구름이 촬영될 경우, 센서별 촬영 영상간에는 구름과 지상과의 상대적 위치가 달라진다. 고해상도 컬러 위성 영상을 생성하기 위해, 영상 정합(image registration) 기법이 사용되는 데, 일반적인 영상 정합 알고리즘은 촬영 영상에서의 특징점(feature point)이 움직이지 않는 것을 전제로 수행한다. 그 결과 이동하는 구름 경계부에서 정합점(matching point)이 추출될 경우, 지상 영역에서의 정합품질이 좋지 않다. 따라서, 본 연구에서는 구름 경계부에서 정합점이 추출되지 않는 알고리즘을 제안하였다. 실험 영상으로 구름이 존재하는 아리랑2호 영상을 사용하였고, 제안된 영상 정합 알고리즘은 지상 영역에서의 정합 품질이 높였음을 보였다.

South Korea makes and manages the ground boundary points record to efficient menage for the installed ground boundary points from cadastral survey with established the Land survey Channel investigation and Cadastre law Section 65 on 17 July 2013. However, this system's negative perception is spreading across the country because of the excessive business process time and inadequate availability. Consequently, this study has analyzed implementation problems of the ground boundary points record. Moreover reasonable development plans have been proposed through the investigation of the advanced foreign cases and interview of the international cadastral experts. Based on this study, it looks forward to improvement more enhanced reliability of the Korean cadastral system.

This research inquired problems that appeared in the previous boundary point coordinates record book, boundary point cover record book, and ground boundary point record book. Also, we suggested the framing plan and based on the boundary point record book for the registration and management of boundary point of cadastral resurvey upon completion on record book. In fact, the outlines of result could be organized into three following points; Firstly, a quick survey can be possible, as reference points for the present situation were available to be checked right away due to unify and manage the boundary point at the record book, even if at the field without the location explanation drawings of boundary points. Secondly, continuous managing of boundary points is possible, since recording the boundary points book with a parcel boundary point, as a unit, make it easily monitoring the formation, critical situation, and extinction of boundary point. Thirdly, the boundary point could be maintained at the boundary points at location, coinciding with geographic features by requesting boundary changes at the time of completion, although it has been made at when the location explanation drawing is made.

Parcel boundary demarcation in agricultural area is commonly performed by terrestrial surveying methods, which have been pointed out as drawbacks to require consuming too much time and heavy expenditure. With the developments of high performance digital aerial cameras, however, studies on cadastral boundary demarcation with an aerial photogrammetric method attract a great attention in recent years. In this paper, an approach is presented to rapidly demarcate parcel boundaries coinciding with real ground ones in agricultural areas by extracting boundaries from the high resolution aerial orthoimages based on aerial targets. In order to investigate the feasibility of the proposed method, the accuracy of coordinates and area of parcel boundaries extracted from the aerial targets appeared in orthoimages compared with that of terrestrial boundary surveying results over the selected two test agricultural areas. Aerial image data were processed taken by a ADS80 digital camera with a GSD of 8cm in Changwon region, and by a DMCII camera with a GSD of 5cm in Suwon respectively. The result shows that the accuracy of parcel demarcation using aerial images is within the tolerance limits of coordinates and areas compared with that of terrestrial surveying. The proposed method using aerial target-based high resolution aerial images is therefore expected to be usefully applied in the agricultural parcel demarcation.

In this study, we presented the improved plans for establishment of boundary monuments and management of records in cadastral resurvey project after examining the Special Act on Cadastral Resurvey which has some problems of them. As the result, we proposed that it is necessary to change the color of boundary monuments for distinguishing with the existing one. And also, they should be established at the confirmed boundary points which land owners have already accepted through the temporary boundary monuments. In addition, the register of boundary monuments has to be unified with present records because they are very similar. We hope that the government should adapt these proposals for the successful project.

The human history has progressed closely related to land. Mankind started land administration as a tool of governance to make land the object of imposing taxation as well as developing the land administration as a concept of securing property rights. People have drawn boundary lines on the ground to form a land parcel according to the usage and/or ownership. Furthermore, the land administration has been developed as a registering system of cadastral records fer the public announcement of fixed boundary instead of changeable ground boundary. Currently the citizens demand the provision of accurate and diverse information on the land which is assessed to has high property value encouraged by the rapid development in the post-industrial society today. However, even though the fact that the Korean cadastral registers produced during the Land Investigation Project are still practically in use causes land-related disputes and promotes public mistrust because of the changed boundaries by parcel mutation, the expansion and contraction of map sheets and the quality deterioration and damage of map paper, but the ultimate resolution is not yet made so far. The distance difference between boundary points are compared and analyzed using TS surveying method in the research as a methodology to resolve the boundary inconsistency, the current problem of cadastral records. Consequently, I'd say that the new surveying method of registering the coordinates of real ground boundary has been regarded as more efficient than considering the matter on the map regardless of urban or rural areas.

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.

Recently, "Cadastral Confirmation Surveying" has been established to promote efficiently and systematically its work. To do so, it is necessary that cadastral control point should be set up and transverse grid coordinates should be determined for high accuracy and boundary restoration based on the cadastral control point. This study expects the potentially institutional problem of detail surveying and the limitation of Network-Real Time Kinematic, introduced to measure the cadastral control point first in the issued regulation, and thus presents the improvement and the management of the block boundary of larger parcel as solutions. This can be applied promptly, when the location difference of ground and border, registered in cadastral record for quake and others, occurs. Thus, the public confidence of cadastral record may become higher and relevant social costs get reduced by the advanced prevention effect of boundary dispute, which represents much to the management of cadastral institution. Provided cadastral confirmation surveying is implemented with the management of the block boundary of larger parcel, proposed in this study.
