Features of performing high-precision survey of the abrasion coast relief by UAV

The results of adaptation of the methodology for high-precision surveying of the ground relief using UAVs for conditions of marine coastal cliff are given in this work. Analysis of the obtained digital images and created digital elevation models showed that this type of survey is optimal for the considered natural object but has a number of limitations. Low cost and speed of data acquisition are the advantages of the method. The processing complexity and interpreting data in the presence of dense vegetation cover and near coastline are disadvantages of the method.
