: 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.

The study analyzes changes in the forest landscape of the Costa Brava over the past century through the comparison of historical and contemporary photographs. The results show a significant increase in forest cover, with the recovery of pine and oak forests, while agricultural areas have declined. This suggests a shift in land use and in the tourist perception of the landscape.

This study provides an overview of the last 40 years of use, and in many cases abuse, of natural resources in Catalonia, with proposals for sustainable management.

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.

The central element is the 1:25,000 geological map; the rest are called peripheral elements. The peripheral elements are: the legend of the cartographic units, the conventional signs, the stratigraphic columns, the geological sections, the stratigraphic relationship diagram, the geological diagram and the complementary diagrams. The geological map shows the distribution of different types of rocks that emerge on the surface of the earth and their relative arrangement. It allows us to deduce much of the arrangement of rocks in the subsoil and to learn about the geological history of a region. It is a two-dimensional graphic representation that allows us to make extrapolations in three dimensions or, even, four if time is considered, depending on the level of reading that is made. It is formed by a set of cartographic units limited by contacts and by symbols that represent other geological elements: surface dip, folding structures, subsoil information (isopachs or isobaths of the Quaternary), slope of recent deposits, morphological indications, landslides and other recent processes, deposits, etc. It also includes symbols of various references (geological sections, drillings, names of major geological structures, etc.).

This article updates the floristic knowledge of the species that colonize the beaches and dunes of the Catalan coast. The study identifies typical species of these habitats, as well as those restricted to dunes. A total of 87 dune systems were sampled, identifying 224 species, of which 87 are considered typical of beach and dune habitats, and 34 are exclusive to these environments. The presence of exotic species reflects human impact on these ecosystems.

The Geoanthropic Map is a cartographic document with applied geothematic content in which the current state of the physical constitution of the territory is represented, at the appropriate scale for territorial planning, as a result of anthropogenic action on the geological environment and the geological conditions for human activity. It reflects those geological elements and processes that directly affect or may directly affect human activities, together with those human activities or actions that modify the morphological characteristics of the topographic surface or that may directly affect the physical properties and behavior of the natural terrain. The Geoanthropic Map includes elements typical of a geomorphological map, while, in the Anglo-Saxon sense of the term, it makes an inventory of natural geological processes and artificial interventions in the geological environment. It classifies natural processes according to their activity and orders them according to the areas of generation of the materials involved, the transport mechanisms, the areas of deposition and the characteristics and geological properties of the deposits. Similarly, it classifies artificial elements and deposits according to the activities that have generated them, to which they give or have given service. This map also includes geotechnical determinations, such as a map of lithological groups and structural elements, the degree of consolidation, the degree of weathering, the degree of rippability and other geomechanical properties of the materials.

This study analyzes the evolution of the beach-dune systems in the Balearic Islands from 2000 to 2021, focusing on their geomorphological management.

The map contains a detailed representation of the relief, depth, seabed type and marine habitats identified on the coast of Catalonia. The area surveyed was the entire Catalan coast up to 50 m depth. The Marine Habitats Map brings together the following data sets: Marine habitats (EUNIS classification level 3 and 4); Complementary marine habitats (EUNIS classification level 5); Seabed type; Coastal strip elevation model; and Bathymetry.

This study analyzes the historical transformation and current situation of the dune landscape in Catalonia.
