This article is devoted to the study of tree and shrub vegetation of the Anapa-bay bar, which has a direct impact on the formation of landscape, and affects the processes of accumulation and transfer of matter. The materials of air laser scanning made it possible to perform automated calculation of all trees and shrubs. Their quantitative and qualitative analysis was performed. The study area is divided into sections depending on the nature of the landscape and vegetation. By processing laser scanning data and digital aerial photography, digital models of each tree and shrub above 0.7 m were construct-ed. For the selected areas, the number of all elements and the area of vegetation is calculated up to each tree. As a result, of the study, the method of software selection of tree and shrub vegetation with automatic receipt of attribute information about the height and diameter of vegetation crowns was tested.
