Application of unmanned aerial vehicles in geodesy on the example of aerial photogrammetric system SenseFly eBee

During the last few years a completely new method for land and object surveying was devloped. Using unmanned aerial vehicle, it is possible to survey a large areas in very short period of time with high accuraccy. Although there are still many uncertainties, it is inevitable that this method represents the future in geodesy and its areas. This paper defines a method for land surveying using SenseFly eBee drone and proccess of creating point cloud, digital model of relief and digital ortofoto map. Using NSSDA standard for spatial data accuraccy on drone products, it was concluded that accuraccy of given results depends on the ground resolution, terrain relief and weather conditions.
