ACCELERATED GENERALIZATION OF THE RELIEF WITH THE USE OF THE DIGITAL ELEVATION MODEL

Abstract

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 threedimensional
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 threedimensional
data on the relief.
