Map visualisation service (WMS) for the data package: Natural risk prevention plan (PPRN) of the municipality of USTOU
Description
The COVADIS data standard on risk prevention plans includes all technical and organisational specifications for the digital storage of spatial data represented in risk prevention plans (RPPs).
Major risks include the eight main natural risks foreseeable on the national territory: floods, earthquakes, volcanic eruptions, land movements, coastal hazards, avalanches, forest fires, cyclones and storms, and four technological hazards: nuclear risk, industrial risk, risk of transport of dangerous goods and risk of dam failure.
Risk prevention plans (RPPs) were established by the Act of 2 February 1995 on the strengthening of environmental protection. The PPR tool is part of the law of 22 July 1987 on the organization of civil security, the protection of the forest against fire and the prevention of major risks. The development of an RPP falls within the jurisdiction of the State. It is decided by the Prefect.
Whether natural, technological or multi-hazard, risk prevention plans have similarities. They contain three categories of information:
• The regulatory mapping results in a geographical delimitation of the territory affected by the risk. This delimitation defines areas in which specific regulations apply. These regulations have the value of easements and impose requirements varying according to the level of hazard to which the area is exposed. The zones are represented on a zoning plan that fully covers the study perimeter.
• Hazards giving rise to the risk are included in hazard documents that can be included in the presentation report or annexed to the RPP. These documents are used to map the different levels of intensity of each hazard considered in the risk prevention plan.
• Issues identified during the development of the RPP may also be appended to the approved document in the form of maps.
These similarities between the different types of PPR and the desire to achieve a good level of standardization of PPR data led COVADIS to opt for a single data standard, generic enough to deal with the different types of risk prevention plan (PPRN natural risk prevention plans, PPRT technological risk prevention plans).
This data standard does not consist of a complete modelling of a risk prevention plan file.
The scope of this document is limited to the geographic data contained in the RPPs, whether regulatory or non-regulatory in nature. Nor is the PPR standard intended to standardize knowledge of hazards.
The challenge is to have a description for a homogeneous storage of the geographical data of the PPR because these data are of interest to several professions within the ministries in charge of agriculture, on the one hand, and ecology, and sustainable development, on the other hand.
