지적재조사를 위한 지적기준점 일원화 구축 방안

Abstract

Our study aimed at analyzing problems in unifying cadastral control point which is the most important element in cadastral re-surveying of Chung-Buk, and suggesting the solution of the problems, so providing basic data in unifying cadastral control point of South Korea. The results of our study are as follows. By observing cadastral control point after setting the central datum area and eastern datum area of Chung-Buk as GPS observed target areas, there are differences with the existing results in RMSE ±0.2972m of X-coordinate and RMSE ±0.2699m of Y-coordinate at the central datum area, and in RMSE ±0.4329m of X-coordinate and RMSE ±0.5399m of Y-coordinate at the eastern datum area. All results are not good, and especially the results at the eastern datum area show greater error. This shows the limit of converting global coordinate system at graphical map based area, and there can be problems in building a nation-wide standard network. Nevertheless, the scale of errors is below 1 meter and small, and this means that the error can be resolved by the current adjusting methods at the current graphical map based area. Therefore, the regional standardization of cadastral control point network for cadastral re-survey is feasible although converting global coordinate system and building a nation-wide standard network are difficult.
