Fuzzy methods of exploration of geo-informational space as a system of systems are considered. The areas of application of digital specialized plan-schemes as fuzzy projections of geo-informational space are discussed. In the process of presentation of the research materials the necessity of forming a single geo-informational space (UGIS) on the principles of geo-interoperability is formulated and substantiated. The sources and tools for obtaining initial data were evaluated. The components of the mechanism of information interaction of geographical, economic and social characteristics of regions were considered. The principles of using the concept of cognitive space to describe UGIS in the project frame SMART (Satellite monitoring of agricultural development of territories). The problem of manifestation of various types of uncertainties at the main levels of obtaining and processing of information is considered. It is shown that for each type of uncertainty it is necessary to carry out: search of the corresponding mathematical description and representation of concrete type of uncertainty; the choice of the mathematical device by means of which it is possible to operate (to adjust parameters) model with the chosen uncertainty; existence of an effective way of measurement of real uncertainty in any analyzed situation; development of methodology of formation of adequate models for real objects and processes of monitoring to choose indicators of uncertainty which can be calculated. It is shown that the spatially distributed information obtained, including by remote sensing of the Earth is three large groups: semantic, metric and topological. The structured set of these groups of information about a particular area, presented in the form suitable for automated processing, forms a digital model of the area. This model is based on the ability of one group of information (as a complex system) to use parts of another group, that is, the ability to mutually use information in each of these groups (systems). In other words, we are talking about geo-interoperability, which is used in the study of the model of UGIS, in the process of forming a digital plan-schemes for receiving of additional information about the objects included in the resulting information product. |
