Accelerated generalization of the relief with the use of the digital elevation model

The description of the technique, the accelerated generalization of the terrain for the construction of maps of the wind regime, is presented. The technique is based on the results of experimental studies of data on digital terrain/relief models using special software. The obtained three-dimensional parametric and polygonal terrain models can be used both for accelerated processing and generalization with the help of special software, and for direct investigation and calculation of aeration modes by methods of computational hydrodynamics. The urgency of using DEM in researching the aeration regime of the territories is due to the need to switch to modern methods of research and verification of theoretical materials. The purpose of creating such three-dimensional representations of relief data is to accelerate the processing of information about the terrain, as well as in the transition to electronic formats for working with three-dimensional data on the relief.
