GPS를 利用한 地籍測量 基準點成果 分析

GPS를 이용해 지적측량 기준점 성과를 분석했다.

Using the control point structured for land surveying project in 1910s, this study is focused on comparatively analyzing the survey results, which have been gained with appointing 3 cadastral triangulation points and 3 subsidiary cadastral triangulation points laid under the ground of southwest Daejeon Metropolitan City, and the results surveyed using GPS to examine rapidity and economical efficiency. In this way, it can improve precision of the survey results. Results of this study are as follows. 1.

Comparatively analyzing the results of existing cadastral survey method by the total station and ones of real-time mobile positioning method, errors have occurred at X axis amounting to average Δx=±0.009m and Y axis to Δy=±0.027m. More precise than the marginal connection error of survey results and examination results amounting to 0.25m, it has turned out to be proper for applying to readjustment of the city streets and control point survey for large unit treatment to contribute to improvement of precision. 2.

Comparatively analyzing the results of existing cadastral survey method by the total station and ones of real-time mobile positioning method, errors have occurred at X axis amounting to average Δx=±0.134m and Y axis to Δy=±0.113m. More precise than the marginal connection error of survey results and examination results amounting to 0.25m, it has turned out to be proper for installing subsidiary cadastral triangulation points.
