A total of three photogrammetric measurements were conducted
and compared to the conventional surveying technique that was also
performed. The UAV's longitudinal and traversal coverage areas of
each photo image were 60 and 40%, respectively. Its flying altitude
was 75 m above the highest point in the entire terrain. The flight planning
used the developed MK FPT. The data was analyzed using the
Agisoft Photoscan Professional software. A total of eight ground-based
reference points were used to compare the target/actual-data points.
