1956 Land Cover Map of Barcelona province. On-screen digitizing of the 1956 land cover (CREAF methodology for the Land Cover Map of Catalonia) on the 1956 orthophotography (Diputació de Barcelona), also known as the American flight.

Information of the Natural Environment within the framework of the SITxell project.

Socioeconomic dynamism in agriculture (the agrarian dynamism is formed by the economic potential of the agricultural sector and by the agrarian structure of the territory)

Information of the Natural Environment within the SITxell project. Reclassification of the geological base 1:50000 of the IGME Magna plan, digitized by the ICC - DMAH.

Information of the Natural Environment in the framework of the SITxell project. Vegetation landscape structure classes in UTM of 2x2 km, from the Habitats Cartography of Catalonia.

Mapping of the food supply service for human consumption taking into account the production of agricultural crops. The approximation established is based on the calculation of average agricultural yields in biophysical value (kg / ha and year) of crops for human consumption. An estimate has been made, based on the expert knowledge of Unió de Pagesos technicians, of the percentage of agricultural production destined for human consumption for each agricultural crop group.

Conservation index to determine a single conservation value of the vertebrates of all UTM squares 1x1 km from the scope of the SITxell project. The following groups of terrestrial vertebrates have been considered: mammals, amphibians, reptiles and birds (wintering and nesting). The methodology followed was: Union of information from nesting and wintering birds considering the maximum conservation value of each of the species in each of the squares. The ICONS values ??of each species and square, both birds and mammals, amphibians and reptiles, have been calculated, raising the conservation value to the fourth power, the maximum power used in the separate maps (that of birds ). Finally, the ICONST value was calculated: the ICONS value corresponding to each bird species was added to each square according to its phenology and the ICONS values ??of each species present in amphibians, reptiles and mammals. Values ??from 0 to 100 have been weighted and represented on the 1x1 UTM grid for the entire SITXELL area.
