Poly-scale principle of urban environment geoinformation monitoring

Abstract

The article discusses general approaches for monitoring the urban environment based on geoinformation technologies. The purpose of these studies is to use the properties of poly-scale geoinformation monitoring in modeling and forecasting the state of the urban environment. The urgency of identifying the spatio-temporal features of the development of the urban environment at different territorial levels is shown. Each territorial level carries its own level of detail. These levels are the global level, regional, local, macro, meso level and primary level. The set-theoretic representation of the principle of poly-scale modelling of objects of the urban environment is considered. Based on this approach, models and methods of geoinformation monitoring at each scale level can be represented as a composition of ordered pairs of different structural types. An example of a hierarchy of methods and models used in studies of the urban environment is given. The concept of basic composition models is introduced. On the basis of such models, a technology for constructing poly-scale compositions is presented. Such compositions make it possible to convey the computational essence of the corresponding mathematical models at each level of the poly-scale approach in the study of the urban environment. A generalized scheme for applying the principle of poly-scale decomposition of a geoinformation monitoring object has been developed. At the same time, at each level of the information space, the construction of the corresponding models of the monitoring object is provided.
