New-Aquitaine: Perimeters of Natural Risk Prevention Plans (PPRN) Avalanche (surface)

This dataset contains the boundaries at the different stages of the development of Avalanche PPRNs (surface objects) in the New Aquitaine region. The characteristic of perimeters is to be the consequence of an official act and to produce their effects from a specified date. According to the PPRs, this perimeter can be of different types: — prescribed scope contained in the prescription order of a PPR (natural or technological); — scope of risk exposure that corresponds to the scope regulated by the approved RPP. This approved perimeter is a utility easement; — scope of study which corresponds to the envelope in which the hazards were studied. NOTE: Detailed metadata by PPRN is available from DDT/M. Some PPRNs may be in the review process. The data is provided for information purposes and has no regulatory value. GIS data for RPPs are not exhaustive.
