Abstract

Unmanned Aerial Vehicle (UAV) Technology is regarded as the latest quantum leap in surveying and mapping, however its use for this purpose is limited in Ghana. This research aims to assess the horizontal accuracy of UAVs equipped with Real Time Kinematic (RTK) capabilities in performing mapping surveys. An experimental approach was used where some selected points on the campus of KAAF University were surveyed using standard Global Navigation Satellite System (GNSS) static techniques. The GNSS coordinates were then compared to those obtained from aerial images captured from a UAV equipped with RTK-GNSS capabilities. The results showed a minimum and maximum difference of 0.003 ft (0.001 m) and 0.101 ft (0.030 m) for differences in Northing coordinates while Easting coordinate differences values ranged from 0.012 ft (0.003 m) to 0.087 ft (0.002 m). A calculated RMSE_XY of 0.069 ft (0.021 m) suggests that RTK-UAV approach is capable of meeting ISO and ASPRS large-scale mapping standards. It is recommended that further studies be done to ascertain how similar UAV methods may be used to meet 3D mapping accuracy standards.
