Map visualisation service (WMS) of the dataset: PPRN hazard zone field movements (St-Sulpice-de-Cognac) in Charente

Surface objects of the hazard zones used for the risk analysis of the plan to prevent natural hazards movements of the St-Sulpice-de-Cognac terrain in Charente. The hazard study evaluates the intensity of each hazard at any point in the study area and leads to the delimitation of a graduated zoning on the study perimeter according to the level of the hazard. The assignment of a hazard level at a given point in the territory takes into account the probability of occurrence of the dangerous phenomenon and its degree of intensity. For multi-random PPRNs, each zone is usually identified on the hazard map by a code for each hazard to which it is exposed. Hazard zones can be described as elaborated data to the extent that they result from a synthesis using several calculated, modelled or observed hazard data sources.
