ABSTRACT

The object of paper is to acquire high-resolution spatial information based UAV photogrammetric method. UAV, GPS-equipped multicopter type, and DSLR camera were used in order to take UAV photography in study area located construction site. air-photo signal plates were installed in study area and ground control survey using network GPS method were applied for orientation and accuracy analysis. The flight plan was considered flight altitude and course to maintain overlap and side-lap, more 70% and 30%, respectively. The result of data was obtained digital ortho image(spatial resolution 2cm) and digital surface model(spatial resolution 5cm). The RMSE of x, y and z axis were calculated using accuracy analysis and application of survey field was observed to process contour map, profile map and calculating earth volume using high-resolution spatial information.
