ABSTRACT

In this study, an accuracy analysis study was conducted on the ground control points layout in photogrammetry using UAV. 17 ground control points and 13 check points were installed in the studied area, and five types of layout were created, and various spatial analysis techniques were applied by combining the performance analysis of aerial triangulation using the check points and the quantitative and qualitative analysis of the results of the ortho mosaic photo and the digital surface model. As a result of the analysis, the layout of the plane in the form of a triangle is important when placing the ground control points, but the height value of the point to be placed should also be considered. In other words, a ground control points can be installed in an optimal location to ensure higher accuracy, taking into account the overall layout and height values of the area being surveyed.
