본 논문에서는 불부합지라 조사 되어 현재까지 관리 되고 있는 지역 및 인근 부합지를 선정하여, 국토교통부에서 제시하는「지적공부의 세계측지계 변환 선행사업 작업 기준」을 적용하여 좌표변환 실험을 실시하고자 한다. 또한 ?07년도 당시 불부합지 조사 지침에 따란 최근 구축 된 고해상도 영상 활용 방법을 통해 실험대상지역의 불부합지 분포와 현황에 대해 재 파악해 보고자 한다. 실험을 통해 현재 지적재조사사업의 관련 자료로 제시되는 불부합지와 부합지의 전국 분포비율과 수량에 부정확성을 밝히고, 도해지적과 수치지적의 가장 큰 차이점 인 필지 경계점의 수학적인 수치 즉, 평면직각종횡선을 통해 도해지적의 세계측지계로의 좌표변환은 지적공부상의“변환”개념이 아닌 세계측지계 성과로의 지적공부“재등록 ? 재구축”의 개념으로 재정립 되어야 함을 제시하고자 한다. 마지막으로 실험지역 분석을 통해 향후 좌표변환을 통한 도해지역의 세계측지계 기준의 지적공부 등록을 위해서 반드시 우선적으로 선행 ? 점검 되어야할 사항들에 대해 제안해 보고자 한다.
The purpose of cadastral resurvey business is eliminating the inconsistencies of digitization, roadbed boundary and realistic boundary on the cadastral records which is in charge of important functions and roles socially and administratively. A detailed business promotion method is largely divided into a direct survey and coordinate transformation of World Geodetic System. Among the business target area, the group cadastral noncoincidence accounts for 14.4% of the whole nation, and the area for cadastral confirmation survey accounts for 12.8% and these two areas are accompanied by a direct survey, and for other areas, the cadastral resurvey business is performed with coordinate transformation and classified as 72.4% of cadastral coincidence. Here, the amount of cadastral coincidence is a figure obtained by deducting the cadastral noncoincidence and cadastral confirmation survey from the nationwide parcels which is a calculated value obtained by estimating and not through an actual complete enumeration survey. The target area of the study was investigated as the cadastral noncoincidence thus the area being managed up to now and parts of nearby coincidence was selected. The tests were largely performed in two ways and the first test was identifying the distribution and the status of cadastral noncoincidence of test target areas through high-definition video utilization method due to cadastral noncoincidence survey instruction in the year of 2007. In other words, it has transformed the orthophoto image of World Geodetic System Standards into a Local Geodetic System to be compared with the current cadastral. The second test is to apply the ''work standards of the previous business for the World Geodetic System of cadastral record'' proposed by the Ministry of Land, Infrastructure and Transport to conduct the coordinate transformation of cadastral to be compared and analyzed with the ground boundary survey data of the World Geodetic system performance. As a result of the test, in the first test, besides the cadastral noncoincidence area which was aggregated in 2007, 3 areas of cadastral noncoincidence were additionally found through qualitative analysis. In addition, it was found that errors such as separation and overlapping of the current KLIS cadastral map graphic information were not erased even after the coordinate transformation. In the second test, the parcels within the cadastral coincidence that satisfy the 50cm standard of mismatch of roadbed boundary and ground boundary was found to be 7.6% for Kwangju City and 11.6% for Icheon City. In addition, the average value of the separation distance between the center of the weight used for the analysis of difference between the roadbed boundary and ground boundary was found to be Kwangju City; cadastral coincidence 3.98m, noncoincidence 1.98m, Icheon City; cadastral coincidence 2.99m, noncoincidence 3.32m, where for the cadastral coincidence, the results have significantly deviated from the standard of 50cm. In addition, after the coordinate transformation, the average value of overlapping area according to the cadastral map and overlapping survey data was shown to be Kwangju City cadastral coincidence 83%, noncoincidence 85% and Icheon City cadastral coincidence 89%, noncoincidence 81%. The results of this study shows that in order to resurvey the cadastral noncoincidence existing within the cadastral coincidence, a high resolution orthophoto can be utilized, and to apply the coordinate transformation method to the cadastral resurvey, the maintenance of cadastral map graphic information error must be preceded. However, because the range of study target area of this study is small, it will be difficult to reflect all the characteristics of regions and starting points as well as reaggregation of cadastral noncoincidence within the cadastral coincidence compared to the entire nation, therefore, in order to implement the coordinate transformation business on the cadastral coincidence, a resurvey of distribution status of cadastral noncoincidence on the first business district by the competent authorities and the maintenance of cadastral map graphic information must be preceded, and to support this, a security of detailed regulations on resurvey business and in-depth study on the graphical cadastre coordinate transformation is thought to be required.
