【 摘 要 】

The article describes a technique of accelerated terrain generalization for mapping wind patterns. The technique is based on the experimental research of data on digital terrain models that was carried out using special software. The developed three-dimensional parametric and polygonal terrain models can be used both for accelerated processing and generalization with special software, and for the study and calculation of aeration modes by the methods of computational hydrodynamics. DEM in studying the aeration mode of terrains is relevant due to the need for modern methods of research and verification of theoretical materials. The purpose of creating three-dimensional representations of terrain data is to accelerate the data processing, as well as to digitalize the work with three-dimensional terrain data.
