Creating topographic plans of terrain sections in the classical way takes a lot of time. It is proposed to use modern equipment and software products to solve the task, which should lead to a reduction in time during the production of work, as well as reduce the cost of the final product. This paper describes the process of drawing up a topographic plan of the chalk pit area for the purposes of landscaping with the use of an unmanned aerial vehicle, followed by processing the data obtained in a specialized software product. The basic preparations for the shooting of unmanned aircraft, also the process of shooting and processing photos in a specialized software product “Agisoft Metashape” for receiving and decoding of the orthophotomap were analyzed.
An approach to laying a network of identification marks on the ground with the use of GPS receivers and determining their spatial coordinates is considered in detail. Also, due to the large volume of work and some technical limitations of the work of the unmanned aerial vehicle, it became necessary to divide the terrain into survey areas, followed by combining the broken sections into a single orthophotomap. The principle of dividing the terrain into separate flight zones is also described in the paper.
