This dataset contains the boundaries at the different stages of the PPRN; development of the PPRN. The characteristic of these perimeters is to be the consequence of an official act and to produce their effects from a defined date. This is the:- prescribed perimeter listed in the prescribing order of #x27; a PPR (natural or technological);- perimeter of #x27; exposure to risks that corresponds to the perimeter regulated by the approved PPR. This approved perimeter is equivalent to easement of public utility (PM1 for PPRNs and PM3 for PPRTs);- perimeter of #x27; study corresponding to the #x27; envelope in which the hazards have been studied.
