New Aquitaine partial: Entities at the origin of the risk for Natural Risk Prevention Plans (PPRN) Flooding (surfacic)

This dataset contains the geographical entities (surface objects) at the origin of the risk for PPRN Flooding of the Nouvelle-Aquitaine region, when GIS data exist. ATTENTION: this dataset is not exhaustive on the perimeter of Nouvelle-Aquitaine, it concerns the perimeter of the former Aquitaine region. The origin of risk characterises the real-world entity which, by its presence, represents a potential risk. This origin can be characterised by a name and, in some cases, a geographical object l' real entity to #x27; origin of risk. The location of the entity and the knowledge of the hazardous phenomenon are used to define the risk basins, the areas exposed to the risks that underpin the PPR. For PPRNs, this entity may, for example, correspond to a geologically unstable area of water. NOTE: Data are provided for informational purposes and no regulatory value __Origin__ The geometric modeling of ' entity at ' origin of risk depends on the type of risk, the context of the PPR, the nature of the generator and its modeling in the data source or geographical repository from which it originates. For example, a water course may be represented by a polygon or a polyline according to its size and width, a Classified Installation for the Protection of the Environment (ICPE) by a point (if the location of its enclosure is not known) or by a polygon (especially from the grey area of the PPRT). The geometry of this class d'objects is optional when: — this geometry is already carried by an object d'a geographical repository or d' an external data source, to which it is then recommended to refer to the identifier; — it does not exist because the origin of the risk cannot be precisely defined or localised (e.g. earthquakes, avalanches, marine submersions, etc.). However, since stable references to external objects are rare in practice, the geometry of l' origin of the risk will often result from the duplication of that of the two; object representing the origin of risk.
