세계측지계 좌표기준으로 평가한 지역측지계 지적기준점의 정확도 분석

초록

It has been requested a continuous geodetic reference system in positioning in the world because of GNSS technology activation as like GPS, GLONASS, Galileo. So, the geodetic reference system was changed from regional geodetic reference system to world geodetic reference system in Korea. The purpose of this study is accuracy analysis of the cadastral control point coordinates based on regional geodetic reference system estimated by the world geodetic reference system coordinates. For the study, first, teat area was chosen in Jinju city and then GNSS surveying was accomplished at some auxiliary cadastral triangulation point, cadastral map control point and urban control point in test area, and finally, the accuracy on the cadastral control point coordinates based on regional geodetic reference system was analysed. The results shows that all cadastral control point coordinates should be calculated in connection with GPS continuous operating reference station under the world geodetic reference system.
