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.

This study intended to extract the spatial data and attribute data from the images of terrestrial photographs to compile the digital map from the images using photogrammetric analysis. In this study, the plane map of present objective area was made using the single terrestial photographs and graphical method, and the spatial or attribute data for the facilities in the area was extracted. Also, it is concluded that the efficient techniques for acquiring spatial and attribute data of the building and road facilities in proper time for the concerning area were suggested.

현행 지적도에는 건물 위치가 표시되지 않아 지적도 활용 시 건물 위치 식별이 어렵고, 지적현황측량에 따른 비용과 시간의 소요와 불편을 격고 있으며, 지상 건물의 경계 침범으로 인한 분쟁과 소송이 일어나고 있다. 건축물 경계 추출에 관한 선행연구에서 수치정사사진과 LiDAR를 이용한 건물 경계를 추출은 원칙적으로 지적측량의 원리와 상이한 기준으로 실제 지상의 외벽 경계선이 아닌 건축물의 옥상층 경계선을 추출하였다. 따라서 본 연구에서는 건물등록을 위해 시도해 보지 않았던 건축도면을 이용하여, 기존연구에서 고려되지 못한 지붕선이나 처마선이 아닌 실제 지적측량에서 기준이 되는 외벽의 경계선을 등록하기 위해 건축도면을 활용하였으며, 등록하는 과정에서 ArcGIS 엔진을 이용하여 개발한 자동 등록 방법을 사용하였다. 지적도 필지 경계선과 건축도면의 필지 경계선을 기준으로 등록한 결과 지적현황측량 성과와 수치지역에서 연결오차로 RMSE가 0.10m, 도해지역에서 0.16m로 나타났다. 따라서 건축도면을 이용하여 지적도에 건축물의 경계를 등록함으로써 지상측량을 보완할 수 있으며, 3차원 지적구축을 위한 기반을 조성하고, 지적재조사사업에서 시간과 경비를 획기적으로 절감할 수 있을 것이다.

The larger black flour beetle, Cynaeus angustus (LeConte) (Diaperinae: Tenebrionidae) is reported for the first time in Korea. C. angustus is economically important as an insect pest in stored products in the Nearctic region, and has been identified in several rice mills in Korea. Taxonomic diagnosis and photographs presenting the morphology of adults and larvae are provided, along with a pictorial identification key to 17 tenebrionid pests detected during quarantine in stored products in Korea.

본 연구는 서로 다른 원점을 가진 구소삼각원점지역과 통일원점지역간의 연속지적도 접합에 있어서 수치지적도를 이용하여 제작한 두 원점지역의 연속지적도 접합도와 최신 항공측량기법으로 생성한 수치정사사진을 중첩ㆍ조정함으로써 상이한 원점으로 제작된 연속지적도 접합에 관한 효율적인 성과 유지 방안을 도출함으로써 국민들에게 측량성과에 대한 신뢰도를 높이고, 도해지적측량의 대안으로 신속하고 정확한 수치적 해석기법의 측량방법을 활용하고자 한다.

In cadastral surveying, there are problems that no area error is allowed where numerical surveying is carried out, and allowable area error is specified irrespective of parcel shape where graphic surveying is carried out. In this research, we derived a general formula of parcel area error necessary for grasping these two problems. The calculations using the derived formula showed that where the coordinate error of the boundary point is set to 5cm+10ppm practically, then even a small parcel of $100 m^2$ includes non-negligible area error of $0.71m^2$. And, it is found that the area error specified by the current egulation is based on a rectangular parcel of 1:5 aspect ratio. These results show that the area error of polygon parcel can be determined by a single formula by specifying the coordinate error of the boundary points, and can be used to revise the current regulations that can be applied uniformly regardless of surveying methods.
