Korean cadastral system is primarily based on the graphical maps, thus, map reproduction by excessive shrinkage or extension, map mishandling and imperfection of surveying techniques have created cadastral non-coincident areas, which caused public distrust as well as considerable difficulties in land administration and policy making. Therefore, in this study, the methodologies for the resolution of the non-coincident problem are presented by means of a comparative analysis between cases of the non-coincident areas. The non-coincidence caused by the mismatch of parcel boundaries can be settled by introducing a coordinate-based system namely ${\ulcorner}$Integrated Land Information System${\lrcorner}$, meanwhile, those by other reasons can be done by establishing and executing a plan that can deliver the unification of the cadasoal and the land registration systems. Governmental intention and budgetary measures for securing the project expenses are essential to make this feasible. If the comprehensive improvement project is completed, the cadastral registers that define the parcel boundary, area and ownership will recover public confidence, which in turn secures land owners' rights by promoting land markets and stabilizing land prices.

지적도(地籍圖)는 한국에서 가장 대축척의 공도(公圖)로 공간정보의 기초가 되며 국토의 효율적 관리와 국가 토지정책 결정에 중요한 역할을 하고 있다. 지적도는 국가 및 개인이 소유한 토지에 대한 물권(物權)이 미치는 영역을 나타낸 지적공부에 속한다. 그러므로 토지소유자에게는 중요한 법적 기록물이며 토지의 역사를 연구하는 토지를 나타낸 도면으로 귀중한 문화재적가치가 있다. 본 연구는 특수도이며 주제도인 지적도를 연구해 향후 촌락사 연구 및 지형의 복원이나 그 지역의 개발과정을 분석 할 수 있는 기초자료로 활용하는데 있다.

This research is aimed at offering a fundamental data for the adjustment of cadastral inconsistency of administrative boundary areas from this time onward by analyzing actual conditions of cadastral inconsistency at the study areas by the use of digital topographic map and digital cadastral map of si-gun-gu boundary area. As a result of examining the actual condition of cadastral inconsistency at the surveyed areas, the extent of cadastral inconsistency of the neighboring administrative boundary areas was assessed as ${\pm}3.15m$ of RMSE on X coordinates and also assessed as ${\pm}2.85\;m$ of RMSE on Y coordinates; in addition, RMSE of the neighboring district of the administrative boundary areas on X coordinates was assessed as ${\pm}1.33\;m$, and ${\pm}0.75\;m$ of RMSE on Y coordinates respectively-thus, this research could suggest the fact that there has arisen a lot of cadastral inconsistency areas at administrative boundary areas.

This study proposed a map registration method of a building construction plan drawing with shape matching of cadastral parcel polygon. In general, the drawing contains information about a building boundary and a cadastral parcel boundary. The shape of this cadastral parcel boundary should be same as that of the corresponding parcel polygon object in the KLIS continuous cadastral map. Thus, shape matching between two parcel boundary polygons from the drawing and cadastral map could present transformation parameters. Translation and scaling amounts could be obtained by difference of centroid coordinates and area ratio of the polygons, respectively. Rotation amount could be obtained by the rotation that presents the minimum Turning function dissimilarity of the polygons. The proposed method was applied for building construction plan drawings in eAIS for an urban area in Suwon. To assess positional accuracy of map registration, building polygons in registered drawings and aerial photos were compared. According to the accuracy of the cadastral map which is the reference dataset of the proposed method, the RMSE of corresponding buildings' corners was 0.95m and 2.37m in new and old urban areas, respectively.

These days, we can't confirm cadastre information about stereoscopic digital map that was consist of 2 dimensions and more difficult to understand of detailed parcel boundary, area, land using for 3 dimensions. An each local government providing three-dimensional that are connected to an aerial photograph with cadastre maps. Satisfaction is high for citizens but, this service additional cost for purchase of an aerial photograph order to provide of it. So far, in various ways are under study about three dimensions using Google Earth which is possible to provides 3 dimensional information by real time for individual parcel situation. The purpose of this study was analyzed an accuracy of overlapping between cadstre maps and an image on Google Earth Web in the each different coordinates system. Also, this paper could be provided for use possibility of 3 dimensions information service with an indicator of using or a guideline of direction for local government which provide 3 dimensions information oneday.

The various hatch patterns supplied by CAD systems are not sufficient for the preparation of geotechnical map and their use can often mislead to a wrong map interpretation. To use, edit, and communicate the geotechnical map information with ease among many CAD user, unified drawing file format is suggested. New hatch patterns are designed and suggested to use with geotechincal jobs.

Linear form of public works such as roads, railways and rivers, generally used as long work crossing administrative districts, can be several hundreds km length and narrow. These linear forms use SCM sheets, which do not include the quadrangle shape, to make a public announcement of topographical drawing in order to get the work approval. the Integrated measurement channel investigation and cadastral act that are established in 2009 apply the ITRF for the composition of design and construction books and coordinates of topographical map in order to get the work approval. However according to the article 5 of additional clause, while the cadastre is maintaining local coordinates, if there is a technical error in the content of the Public Announcement of Topographical Drawing that used the SCM, the question of responsibility of land borders and the efficacy or not of the announcement is raised as an administrative measure. After analysing the causes and enforcing coordinate conversion and correction taking into account linear form work's features, the result was reflected in the existing SCM. As a conclusion, the present study proposes the improvement of the procedures of the Public Announcement of Topographical Drawing.

Vectorizing for input processing of map is the most time and cost consuming task, and the quality of vector data depends on that processing result. Therefore, it is an important task to develop a good vectorizing system in the GIS. Thinning algorithm is the most important technology for deciding the quality of vector data in the vectorizing system. In this paper, as a suitable algorithm for map vectorizing we considered several algorithms that preserve topological and geometric characteristics, and have no distortion of the contour line. As a results, we implemented WPTA4 and well known thinning algorithm, and compared WPTA4 execution results with the others.

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.

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.
