    The Radiosonde Station information set provides information on the identification and location of the radiosonde station owned by the Meteorological Service of Catalonia. It is a vector geographic information set of 2D at a scale of 1: 5,000. The data recorded at the Radiosonde Station allow a vertical characterization of the atmosphere by means of instruments transported by a balloon that is launched automatically twice a day, at 11:00 and 23:00 hours UTC. The station is located on the roof of the Faculty of Physics of the University of Barcelona and belongs to the World Meteorological Network through the GTS (Global Telecommunication System).

    The XRAD provides information on the identification, location and status of the network of radars (XRAD) owned by the Meteorological Service of Catalonia, which has four radars integrated into the XRAD. The XRAD is designed for the identification of meteorological echoes in the atmosphere and to provide quantitative estimates of rainfall of great meteorological and hydrological interest. The network is made up of four Doppler type radars that operate in band C: the radar of Vallirana, the radar of Puig d’Arques, the radar of Panadella and the radar of Tivissa-Llaberia. It is a 2D vectorial set of geographic information at 1:5,000 scale.

    XEMA provides information on the identification, location and status of the network of Automatic Meteorological Stations (XEMA) owned by the Meteorological Service of Catalonia. On the occasion of the entry into force of Law 15/2001, of 14 November, the XEMA was created by grouping the stations of three different networks: the Network of Automatic Meteorological Stations (XMET) of the Meteorological Service of the Directorate General of Environmental Quality of the Department of the Environment; the Agrometeorological Network of Catalonia (XAC) of the Department of Agriculture, Livestock and Fisheries; and the Snow-related Network of Catalonia (XANIC) of the Cartographic Institute of Catalonia. The EMAs are equipped with sensors that provide information on weather variables that allow to know the weather situation in real time and improve the country's climate knowledge (temperature, relative humidity, wind speed and direction, global solar irradiance, precipitation and atmospheric pressure). It is a 2D vectorial set of geographic information at 1:5,000 scale.

    The XDDE provides information on the identification, location and status of the set of geographic information Network for the Detection of atmospheric Electric Discharges v1.0 (XDDE) owned by the Meteorological Service of Catalonia. The system allows the real-time detection of storms, as well as the very short-term forecast of their trajectory. The XDDE consists of four remote stations and a central processing system located at the SMC headquarters. The stations are located in Begues (el Baix Llobregat), Castellnou de Seana (el Pla d’Urgell), Muntanyola (Osona) and Amposta (el Montsià). The arrangement of the detectors is designed to provide good coverage throughout Catalonia, with an error in the location of lightning less than a kilometer for much of Catalonia. It is a 2D vectorial set of geographic information at 1:5,000 scale.

    The Atlas focuses on the climatic characterization of Catalonia in the period 1961-1990. This climate period has been established by the World Meteorological Organization as one of the international reference periods for climate series statistics. It consists of thermopluviometric information structured in 32 layers: 18 layers of precipitation (12 of the monthly averages, 4 of the seasonal averages, 1 of the annual average and 1 of the seasonal pluviometric regime); and 14 temperature layers (12 of the monthly averages, 1 of the annual average, and 1 of the annual average thermal amplitude). It is a database with 2D vector information at a scale of 1: 750 000.

    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.

    Limits of the areas of natural interest defined in Decree 328/1992, which approves the Plan of areas of natural interest (PEIN), and any subsequent modifications that may have occurred. This base includes spaces at a scale of 1:50 000 and, in some cases, 1:5 000. The PEIN establishes a network of spaces representative of the rich landscape and biodiversity of the territory of Catalonia, from high mountains to coastal plains, and from Euro-Siberian forests to semi-desert wastelands or marine spaces. The PEIN is the higher level planning instrument that structures the system of protected areas of Catalonia and integrates this system within the whole territory, as it is a sectorial territorial plan framed within the Territorial Plan of Catalonia (1995). Subsequent to its approval, specific modifications to the rules and limits have been approved by decree, as well as extensions or additions of new spaces.

    Limits of the figures defined in Law 12/1985, of natural spaces: national park, natural places of national interest, natural reserves and natural parks. It also contains the limits of wildlife reserves defined in Legislative Decree 2/2008, of 15 April, approving the Revised Text of the Animal Protection Act. The limits of each space are established in the legal regulations by which the space is declared or modified.

    Boundaries of the natural spaces of Catalonia that form part of the European Natura 2000 network. Natura 2000 is a European ecological network of areas that may have been proposed as special protection areas for birds (ZEPA) in accordance with the Directive 2009/147/CEE, also known as the Birds Directive, and/or as Special Areas of Conservation (ZEC) in accordance with Directive 92/43/CEE, also known as the Habitats Directive. In the first instance, the Government of Catalonia approves the proposal for sites of Community importance (LIC) for the Natura 2000 network of the areas of the Alpine and Mediterranean biogeographical regions. Subsequently, the European Commission adopts the conformity of this proposal and finally the Government of Catalonia declares the LICs as ZECs.
