dc.description.abstract본 연구는 산악지 표고결정에 있어서 GNSS/Geoid기술의 활용가능성을 분석하고자 한 연구이다. 연구를 위하여 지리산 일원에 테스트베드를 설정하고 GNSS관측을 실시하였으며 EGM2008, KNGeoid13, KNGeoid14 지오이드모델을 적용하여 39개의 수준점의 정표고를 결정하였다. 그리고 국토지리정보원의 수준점 성과와 비교하여 정확도를 평가하였으며 그 결과를 항공사진측량 작업규정에서 분석하였다. 연구결과 GNSS/Geoid기술에 의한 표고결정 정확도는 KNGeoid14 지오이드모델을 적용하였을 때 ±7.1cm가 되는 것을 알 수 있었으며, 항공사진측량의 항공삼각측량에 필요한 지상의 표고기준점을 구할 때 도화축척 1/1000이하의 축척에는 사용가능함을 확인할 수 있었다.-
dc.description.abstractThe purpose of this study is to analyze the feasibility of using Global Navigation Satellite System(GNSS)/Geoid technology in determining orthometric height in mountain. For the study, a test bed was set up in and around Mount Jiri and GNSS surveying were conducted. The orthometric height of 39 benchmarks was determined by applying the EGM2008, KNGeoid13, and KNGeoid14 geoid models and the accuracy was estimated by comparing with the offical Benchmarks orthometric height value issued by National Geographic Information Institute(NGII) and finally, the results were analyzed with the Aerial Photogrammetry Work Regulations. As a result of the study, it was found that the accuracy of the orthometric height determination by GNSS/Geoid technology was ±7.1cm when the KNGeoid14 geoid model was applied. And also, it can be confirmed that it is usable for the less than 1/1000 plotting scales as a vertical reference point for the aerial triangulation in Aerial Photogrammetry.-
