Unmanned Aerial Photogrammetric Systems in the Service of Engineering Geodesy

The development and price reduction of unmanned aerial systems enables their wider use. Using unmanned aerial systems the Earth' surface and objects on it can be documented from new perspectives, simpler, quicker and with better quality. Also, the development of computers and automatic correlation algorithms has enabled the automatic acquisition of large amounts of data per unit time. Drones are equipped with technology that has been used in geodesy for years, e.g. camera, GPS, INS and, of course, the RF device to transmit signals to Earth. Such aircrafts can be controlled from the ground by the operator or it can be completely autonomous and do the survey automatically after a predefined flight plan. This method is extremely useful for documenting large areas or longer linear objects like bridges, embankments, buildings etc. Choosing a predefined path allows photogrammetric survey in the constant scale, which guarantees constant measurement accuracy. It is necessary to modernize the existing regulations and to harmonize the legislation with the trends and the market needs, so that this new area of geodesy could develop accordingly. Also, it is important to clearly define the required accuracy and the quality of data for both, licensed engineers and end users alike.
