The features of efficiency evaluation of a geoinformation system as an element of a situational center

The article continues the thematic series of the articles devoted to information systems efficiency evaluation. In this case, a geoinformation system (GIS) is considered as an element of a situational center. In the article, the integral index of efficiency of GIS usage (IEUGIS), allowing to combine assessment of visualization quality of the dynamic configuration of the electronic atlas by the criterion of visualization and the costs of embodiment of the technical part of the GIS itself is suggested. The calculation and experimental verification of GIS efficiency are presented. This approach allows one to evaluate GIS efficiency when using them as a part of situational centers that is of great practical importance in improving the management mechanism by corresponding organizational systems.
