摘要:The use of unmanned aerial vehicles (hereinafter referred to as “UAV”) is one of the most popular ways of collecting objective spatial data on the land plots under survey. The main advantages of UAVs include the significantly lower cost of surveying, design and complex cadastral works compared to traditional methods of determining coordinates (e.g. performing a tacheometric survey and plane-table survey). The designed sector of block No. 9 in the Yurga urban district of Kemerovo region with cadastral No. 42:36:0102001 (land category: residential), comprising 22 apartment buildings, is taken as an example. The economic performance of land plots marking, carried out with cadastral accuracy, based on data obtained using UAVs and without the use thereof, is assessed.
