The system of forming and obtaining complex assessments of the ecological state of environmental objects on the basis of heterogeneous data and modeling results, taking into account the characteristics of uncertainty was created. Based on the conducted metrological analysis of the main types of data, algorithms for the construction of a normalized space of estimates, which provide the formation of complex and comprehensive estimates based on the layer-by-layer organization of projects in the technology of geographic information systems, were implemented.
The paper is focused on the issues of combining different types of data and the results of modeling to obtain a comprehensive assessment of the state of objects of the ecological system and forecasting the development of the situation. On the basis of the metrological analysis of the main types of data the method of construction of the fixed assessment space is proposed, providing the formation of complex and comprehensive assessments on the basis of the organization of stratified projects and geographic information systems technology.
