At the beginning of the XXI century in Russia, as in the whole world, there is an increase in the number of natural and man-made disasters. In order to cope with the growth of costs associated with damage from them, decision makers need appropriate tools to assess the risks of hazardous events.

For coastal areas, a number of hazardous natural events, representing a threat to the population and the environment, is particularly characteristic. At the same time, they experience a press of increasing anthropogenic loads. In this regard, an actual problem is the formation of an integrated system for marine environmental management, including a unit for assessing the risks of natural hazards, which could provide economic and environmental safety.

The present work is devoted to the development of the geoinformation resource’ structure of natural hazards risks for marine economic activities. In the article software and information base for the projected geoinformation system are considered. Advantages of implementing the system in the form of a web application, base on web-services, are: simplifying the providing of structured information to users and no need to install additional client software. The concept of layers was used in constructing the application structure. The description of three main layers is presented: representations, domain logic and data source.

The informational basis of the system is the geodatabase, which includes the base and thematic sections. The base section includes a topographic and geographical basis for cartographic material. The thematic sections include data groups that characterize hazards and elements at risk. This makes it possible to provide information in terms of the consequences of hazards, which is in accordance with the recommendations of WMO.

It is proposed to implement in the future a corresponding geoinformation resource for the Sea of Azov, based on the developed structure.
