The most developed area of information support of environmental studies are geographic information systems (GIS). Important here is the possibility of the formation of cartographic images of elements of the environment with the geo-referenced, and with the release of specific information that is fundamentally necessary in the search and identification of emergency situations such as floods, dust storms, landslides, volcanic eruptions, etc. Standard GIS systems are not particularly dynamic, and thus not capable of indicating rapid change. We propose GIMS (GIMS = GIS + model), which combines GIS technology with dynamic modeling. In other words, the functions of GIS are enlivened by the introduction of a new grid - time scale. The result is a forecasting tool and, therefore, may be used to carry out a dynamic integration of environmental information. One of the important functions of geoinformation monitoring is the detection and identification of emergency situations that may occur in the environment. The rich experience of solving this problem with the use of radiophysical, optical and other methods suggests that a successful outcome requires the synthesis of a wide range of multi-channel measurements and an hierarchical structure for searching and processing information from various levels of the monitoring system, which could include satellite, airborne laboratory, ship based observations, and on ground or overwater stationary observation points. Problem detection and identification of anomalous phenomena in the environment at every level is achieved with the use of appropriate technologies, but the efficiency of its solutions is only guaranteed by all levels together. Satellite view level provides periodic elements of the environment and provides the primary indication of an abnormal formation of the next level. Signal flow through all levels (satellite to point observations) answers whether the environment really breached its parameters in a certain region, or if it was a false signal. So, from the above it can be concluded that the problem of information support for environmental monitoring is in trying to accurately characterize a system emergency. Each level of the monitoring system requires a specific set of information structures. Thus, by carrying out a multi-step hierarchical search for anomalies identified by a certain set of criteria, the monitoring system generates an information field for environmental services and may trigger responses by other organizations in the resolution mode or regulated access through information networks.
