Sažetak
The possibility of using unmanned aircraft (UA) for the need of geodetic surveying was investigated in such a way that a test field consisting of 30 ground control points (GCP) and checkpoints (CP) was established. The test field was first measured by the classical method of geodetic surveying, the polar method using a total station. After that, all points were again measured by the GNSS RTK method. The GNSS RTK method was used to determine the coordinates of points in the official Croatian coordinate system HTRS96/TM, additionally, the polar method increased the positional "strength” of points in all directions, i.e., improved the relative accuracy between all points. Using UA with different image sensor characteristics, the test field was measured by an aerial photogrammetry method at different flight heights for the purpose of obtaining digital orthophoto. The absolute orientation of the model was performed using the external orientation data of each digital image based on GNSS and IMU unmanned aircraft sensors as well as using GCP. Accuracy analysis of aerial photogrammetry was performed by considering the survey data collected by classical methods accurate and comparing them with the coordinates obtained by aerial photogrammetry method from digital orthophoto.
