Information of the Natural Environment in the framework of the SITxell project.Localització (not exhaustive) of habitats of reduced surface not included in the Habitats Cartography due to their small size.

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.

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 of the Natural Environment in the framework of the SITxell project. Units of the Legend of the Habitats Cartography of Catalonia corresponding to agricultural habitats, with the addition of classification parameters based on the presence and arrangement of natural vegetation.

Information of the Natural Environment in the framework of the SITxell project. Natural habitats and corresponding valuation, in the fluvial area of the main courses of the Ter river basin in the province of Barcelona, with division by river and municipality.

Distribution of soils in the territory according to their morphology and characteristics physical, chemical and biological, and those of the environment where they are found.

Information on the Natural Environment in the framework of the SITxell project. Natural habitats, and corresponding valuation, in the fluvial area of the main courses of the Llobregat river basin up to the city of Abrera, differentiated by river basins and sub-basins.

Classification of soil according to its agrological capacity (ability to sustainably produce the most common crops in an area), in one of the 8 classes established by the Generalitat de Catalunya (Government of Catalonia).

: 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.

Pla d'Ordenació Urbanística Municipal (PGOU) of Tordera is the cartographic instrument of urban planning of the municipality that directs the development of the municipal territory. The set of geographical information of the PGOU of Tordera consists of multiple plans, all of them in PDF format, which form two blocks of cartography: information plans and management plans. The planning areas of the municipality defined by the PGOU planes are: general and organic structure, land classification, zoning of urban and building land, regulation of the building and regulation of non-urbanizable land.
