Abstract

In the paper we consider the possibilities of using geoinformation technologies and digital models in solving problems of environmental territory monitoring. The purpose of the work is to demonstrate the use of geoinformation technologies and digital models in solving problems of the spatial processes modeling. The authors used a digital model of the relief for the mountainous and coastal regions of the Krasnodar territory developed at the Kuban State University for cartographic modeling of pollutant migration processes. The possibilities of using the model and application for the environmental monitoring and creation of forecast models are described.

GIS have proven effective in demographic studies, transport infrastructure development, mineral exploration, seismological and environmental monitoring, natural disaster forecasting, etc., but GIS themselves are not designed for independent 3D modeling. For environmental models, an important role is played not so much by spatial geodata as by the characteristics of the studied process obtained as the results of modeling aggregated in GIS. The paper considers a model of dispersion and transport for a pollutant in the atmosphere. The distribution of pollutants in the flow of air masses is described by a non-stationary convection-diffusion equation.

Using the constructed digital model of the territory of the Krasnodar region, the calculated model data is visualized in relation to the map. With the help of built-in tools, when working with attributive and graphical information, it is possible to integrate the results of modeling with digital model maps in the range of parameters significant for practice.

Keywords:
