Effective control of coastal territories in conditions of increasing anthropogenic impact requires objective, quantifiably justified methods for assessing the degree of transformation of the landscape. Traditional cartographic and visual approaches do not provide sufficient detail and do not allow to identify local anomalies in the surface structure resulting from urbanization, recreational load or construction activity. This limits the possibilities of environmental control and spatial planning. Development of a method for automated monitoring of the condition of the coastal zone based on the analysis of aerial laser scanning data in order to classify territories according to the level of anthropogenic load. A method of coastal territory zoning is proposed, which implements the processing of airborne laser scanning data and the allocation of areas with varying degrees of surface modification. The method is based on the calculation of local geometric features: height difference, slope, density of points, residual roughness. The proposed method is implemented as a software package using Python. Visualization of the load zones is performed in the format of a 3D model. The developed method makes it possible to automatically identify areas of the coastal territory affected by urbanization, recreation and other forms of anthropogenic transformation. The resulting maps can be used by environmental monitoring bodies, architectural planning and when making decisions about environmental protection measures.
