  The results of studies on the development of computational techniques for
geometric and thematic characteristics of the underlying surface and urban
canyon are presented. These characteristics are intended for parameterization
of the local model of energy-mass exchange between the surface layer of the
atmosphere and the surface of the active layer of the underlying urban areas
(cities). Multiscale database of parameters of the underlying surface with a
resolution of 200, 500 and 1000 meters is obtained. The use of
micro-meteorology models that take into account the specificity of the urban
environment, coupled with mesoscale prognostic models will significantly
improve the sound quality of the meteorological fields and local operational
weather forecasting in the metropolitan areas where considering the
hydrometeorological situation is particularly important.
