The combined use of a digital aerial camera and an airborne laser scanner (LIDAR) for aerial survey of the earth's surface is the most advanced and most productive technology for obtaining high-precision spatial data and allows you to perform significantly more work in less time than traditional topographic survey. The work technology used by our enterprise allows us to produce topographic (engineering and topographic) plans and maps of the entire scale series up to 1:50 0 with high quality and in a short time. The principles of operation of the aerial survey equipment complex are as follows: during the flight of the aircraft, the on-board GNSS receiver determines the coordinates of the flight trajectory, the inertial navigation system fixes the tilt angles of the equipment with a frequency of 200 Hz, the air laser scanner acts as a rangefinder, fixing the angle and distance from the aerial survey equipment to the underlying surface ... To clarify the spatial position of the aerial survey equipment during the flight, a network of ground GNSS base stations is created, due to which the differential correction is determined. As a result, an array of laser reflection points is obtained, in which each point has spatial coordinates XYZ in the required coordinate system with high accuracy and a set of aerial photographs with the parameters of their external orientation. Processing of the received data and drawing up cartographic products are the next stages of the production process, which have also been successfully implemented at Aerogeomatika LLC. Thus, at our enterprise, the entire technological chain is carried out, from the organization and conduct of airborne laser scanning and digital aerial photography to the release and printing of finished topographic (engineering and topographic) plans and maps, which is especially important for high-quality work in a short time.
