ANALISIS KETELITIAN TERRESTRIAL LASER SCANNER TERHADAP KERANGKA DASAR HORIZONTAL DAN KERANGKA DASAR VERTIKAL DALAM PEMETAAN.

The purpose of this study is to analyze the application of Total Station and Laser Scanner in geodesy surveys to obtain accurate coordinates and evaluate polygon shapes. The Total Station method is used to measure the angle and distance between points, while the Laser Scanner is used to generate point cloud data which is then processed. The data from the two methods were compared to determine the accuracy of the coordinates using the Root-Mean-Square Error (RMSE). The results showed that the Laser Scanner provided higher accuracy than the Total Station, with an RMSE value for horizontal coordinates of 0.038 meters and an elevation of 0.020 meters. Field evaluation also validates the accuracy of the scan results with direct measurements using a hand meter. This study not only confirms the superiority of the Laser Scanner in producing accurate geospatial data, but also supports the development of methodologies and technologies in geodesy surveys. The results of this research make an important contribution to the development of civil engineering science, especially in the context of 3D mapping and its application in infrastructure and construction projects.
