Calculated estimation of the linear resolution on the ground of a digital unmanned aerial photography system for taxation decryption tasks (issue status, problematics, models)

The article discusses the problems of calculating the linear resolution on the ground, as an indicator of the accuracy of the taxation and decryption measurements on digital aerial photographs obtained by means of UAV. The work is based on the analysis of more than 100 scientific publications on the theory and methodology of digital image registration, assessment of their quality and metric properties, general and forest aerial photography, forest taxa measurements and forest decoding, optimization of the choice of UAVs in application to the tasks of forest taxation and urban landscaping. As the results of the work, a modified version of the mathematical model and calculation algorithm are proposed, which, based on the determination of the linear resolution on the ground of a digital aerial photography system allows: to assess the estimated accuracy limits of decryption taxation for the current level of UAV development; to evaluate the required accuracy of groundbased taxation measurements when developing decryption models for UAV taxation; to make an adequate choice of UAVs in standard configuration for production of taxicab aerial photography; to carry out an independent selection of UAV filming equipment for solving the tasks of decoding forest taxation and inventory of urban landscaping.
