Allows visualization and query vector data and information associated alphanumeric Networks Hydrological Environment Control, as defined in Directive 2000/60 / EC of the European Parliament and of the Council of 23 October 2000 establishing a framework for Community action in the field of water policy in the form of networks.

Information regarding an area exposed to an avalanche. Mapped based on analysis of the terrain and of signs that avalanches leave in their path, mainly, in forests. In Avalanche Zones, avalanches occur frequently and are of different sizes. Avalanche Zones have been systematically mapped throughout the region. They are shown in orange. There are two types of Avalanche Zones: zones where avalanches usually follow the same path, shown in orange, and zones where avalanches usually follow different paths, shown in pale orange.

Information regarding an avalanche observed recently. Mapped based on direct observation of the event or observation following it. The information is obtained based on the nivometeorological observation network, rescue groups, countryside wardens, mountain guides, and ski and mountain resort personnel. In the event of important episodes and accidents the IGC technicians also gather information. The elements mapped mainly include the extent to which avalanches affect populated areas, roads, ski resorts and people who carry out mountain activities. Data began to be gathered in 1986. It is shown in blue.

Inventory of defence structures built to reduce the risk of avalanches. Single and lineal structures are documented, such as artificial avalanche release systems, road barriers, breakers, deflection structures, retention nets, screens, wind baffles, deflectors, rigid and flexible barriers, retention walls, reforestation and controlled areas.
