It represents the time of avenue or arrival of the floods from sectorizations of the fluvial courses.

Identification of the municipalities through which the pipeline passes.

It represents the areas of avalanche observation by the population, identified from a population survey.

This dataset contains the geographical location of sirens installed on dams, designed to act as an alert system in the event of a dam or dike breach. The installation points have been determined based on acoustic dispersion models and an analysis of flood-prone areas with resident populations, aiming to optimize coverage and ensure immediate notification to the people living in these areas.

It represents the aproximate route of the oil pipelines.

It represents the areas of winter observation of avalanches.

The ZIF (defenceless zone) is defined as the minimum security zone necessary to guarantee the viability of self-protection of vulnerable elements in the context of an accident in the transport of dangerous goods. The extension of this zone is conditioned by the necessary response time and the intensity of the effects of foreseeable accidents. The distances of the ZIF for the scenarios of long-range toxic cloud, short-range toxic cloud, serious explosion, flammable cloud and puddle fire are established in "The Technical Instruction of the DGPC regarding the preparation of reports on the conditions minimum requirements that new urban developments must comply with to be located within the identified chemical risk zones due to the transport of dangerous goods by road and rail" (ITMMPP).

Thematic coverage of the municipalities of Catalonia in which the maximum danger level in relation to the transport of dangerous goods by rail is represented. The danger level takes into account, apart from the flow of dangerous goods, the type of substances transported. The average data on the transport of dangerous goods from the last four years has been used with the aim of obtaining more stable data over time and minimizing the current variations derived from the socioeconomic context of each specific year. The danger may come from a section of the railway network that crosses the municipal area or by a section that, without crossing the territory, is at a distance equal to or less than 500 meters from the municipal area.

Location of alarms to warn the population if there is a chemical risk in the case of an accident in premises nearby.

Subzones within zone I or zone of urgent protection measures. It corresponds to the geographic area affected by the passage of the radioactive cloud within a 10 km radius circle around the nuclear power plant (with the nuclear power plant at its center). In the area of ​​zone I, the sector of preferential attention and the zone of preferential attention are also defined.
