A drone was used to map an area of 18.99 hectares with millimeter accuracy. The mapping process involved creating eight targets on the ground that were visible to the drone at a height of 60 meters. The coordinates of the targets were determined using GPS methods. Classical topographic methods have also been used to calibrate the drone's GPS for further correction and accuracy. A flight plan was created using DJI software, which determined the flight area, height, time, frame rate, camera tilt, battery level, direction of flight, wind speed, latitude, longitude, and flight speed. The flight plan was uploaded to the drone's memory, and the drone was flown according to the established parameters.. This technology allows the creation of high-resolution digital maps. With the help of UAV technology it is possible to provide topographic support for the revision of General Urban Plans (GUP), elaboration of Zonal Urban Plans (PUZ), feasibility studies for investment works, such as road infrastructure, railways, electrical networks. Also, this technology allows to make high-resolution digital maps (orthophotoplans), as well as 3D models of some objectives - historical monuments, buildings, land. A drone can be defined as an unmanned aircraft capable of autonomous navigation without external control using autopilot or that can be controlled by a remote control device. This technology allows the creation of high-resolution digital maps.
