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.
Volcanological map of the Volcanic Zone Natural Park of Garrotxa, made together by the Cartographic Institute of Catalonia, the Geologic Institute of Catalonia and the Volcanic Zone Natural Park of Garrotxa.
: Information regarding an avalanche observed in the past. Mapped based on a survey of inhabitants of the area where the phenomenon took place. The boundaries shown are based on the explanations given by the witnesses consulted. Information is usually taken from Avalanche Zones close to inhabited areas where avalanches have historically interfered with human activity. For this reason the majority of the information is found around these zones. They are shown in purple. Cartography often maps only the avalanche arrival zone, as the descriptions usually refer to their extent and the damage caused.

Delimitation and attributes that characterize each element of the Inventory of Spaces of Geological Interest of Catalonia. Spaces of geological interest are places of interest, due to their unique and/or representative character, for the study and interpretation of the origin and evolution of large geological domains, including the processes that have shaped them, the climates of the past and their paleobiological evolution in a sufficiently continuous and homogeneous manner throughout its extension, one or more notable and significant characteristics of the geological heritage of a natural region, with geometric or geographical continuity of the characteristic and with the homogeneity of this in all its extension. This set of information was born in 1999 from a collaboration agreement between, at that time, the Department of the Environment of the Generalitat of Catalonia and the Autonomous University of Barcelona.
The Soil Map at a scale of 1:25 000 is a map of edaphological content covering the entire surface of Catalonia, divided into 304 sheets defined according to the official 1:25 000 cut. It is a cartographic document that provides an overview of the edaphic structure of the country and, in summary, provides information on the distribution of soils in the territory, their morphologies, and their physical, chemical and biological characteristics. GT IV is the instrument for the realization of the Soil Map 1:25 000.
Topographic database that covers all the territory of Catalonia, compiled in 2.5 dimensions. It contains data relating to the relief, the hydrography, the transportation networks, the settlement and the auxiliary infrastructures, the toponymy, the reference points and a reduced set of land cover and vegetation classes. The reference scale is 1:25 000.
