    Inventory of defence structures built to reduce the risk of avalanches. Single and lineal structures are documented, such as artificial avalanche release systems, road barriers, breakers, deflection structures, retention nets, screens, wind baffles, deflectors, rigid and flexible barriers, retention walls, reforestation and controlled areas.

    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.

    Measuring and analyzing earth's gravitational field at the surface is one of the main tools to study the structure and composition of the Earth. The gravity method helps Geology in describing subsoil lithological variation based on density anomalies.

    Map of the world at scale 1:15 000 000 (version in three assembling sheets) or 1:22 000 000 (version in a single sheet) represented as a planisphere with Robinson Projection. Polar regions are at scale 1:25 000 000 or 1:35 000 000 with Universal Polar Stereographic (UPS) projection. The cartographic content includes the continental relief, vegetal cover, states and their borders and capitals, main cities, main Unesco World Heritage Sites, submarine relief and bathimetric colours. The toponimy is in catalan language.

    This method puts emphasis on the measurement of anomalies of the Earth's magnetic field, caused by the presence of reservoirs or structures on the subsurface. This technique allows to assess changes of nT in the Earth's magnetic field caused by the presence of some minerals. Those minerals are characterized by high magnetic susceptibility such as the magnetite.

    Seismic reflection method is based on the propagation of seismic waves inside the earth. This method analyzes the reflected waves which are generated on or near the surface by a seismic source, travel down into the ground, reflect at a discontinuity (density and velocity contrast) and travel back up to the ground surface. Digital processing of seismic reflection data offers the opportunity to create cross-sectional images of the subsurface (seismic reflection section) showing the amplitude of the reflected wave at the correct horizontal and depth coordinate of the reflection point.
