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.

Mapping of the erosion regulation service representing the capacity of ecosystems (mainly vegetation) to retain soil and prevent its gradual or sudden erosion (landslides). Due to the lack of empirical data, an approximate quantification based on the potential erodibility index and generic values of soil cover capacity to control erosion was chosen. A polygon layer has been created.

Cartography of the habitats of the Barcelona counties, version 3. This is an update of version 2 (2012) in which, apart from the planimetric revision based on the ICGC orthophotomaps, the legend becomes the List of habitats in Catalonia, each polygon contains a single habitat, the minimum area is reduced to 1.5 ha, adding a layer of points for small habitats. The attributes of the map contain the CORINE habitats, the habitats of community interest (HIC), the EUNIS classification of habitats, the classification of the LPEHT (Spanish Standard List of Terrestrial Habitats), as well as several attributes of valuation of the natural interest and the degree habitat threat.
