On practice of integrated environmental mapping of urban areas taking into account pollution dissemination

Abstract

The high level of environment pollution is specific to urbanized territories. The efficient solution of city ecological problems requires considering urban environment as a dynamic system and taking its development over time and space into account. This can be achieved through a complex analysis of time and space dynamics of pollutants in accordance with natural conditions and city infrastructure. The study determines an approach to the environmental assessment of the urbanized territory based on geoinformation analysis and 3D cartographic modelling time and space dynamics of pollutants spreading in the urban environment. The approach to assessing it, taking into account the patterns of pollution dissemination is substantiated. The logical sequence of integrating heterogeneous environmental data for pollution distribution modelling is offered. The digital relief and terrain models of Novosibirsk city are formed. The environmental database of Novosibirsk city is developed. The city area zoning by composite index regarding environmental risk is given. A 3D model of pollution dissemination is developed.
