The author demonstrates the possibility of forming complex information constructions with the use of an information environment.

The article describes the spatial information storage, shows the features of spatial information and of such storage systems formation. Requirements for information storage technologies and for the data management in storage systems are determined. Cartographic information storage and updating features are shown. The article proves that intelligent solutions are the most efficient means of working with large amounts of spatial data.

The paper studies the spatial information models as types of information models, reveals the properties of these models, shows the common features of information spatial models and intelligent models. The features of tasks solution, using spatial information models are described.

This article investigates management control through the contingency approach, describes information models of special purpose: information situation and position information, discloses the content of models and their features, shows the interrelation between the models and the impact of uncertainty on the models quality, proves that these models serve as the basis for situational management and improve management quality.
