Data batch direct download service (WFS): Plan for the prevention of natural hazards (PPRN) of the municipality of Vernajoul

The COVADIS data standard for risk prevention plans includes all the technical and organisational specifications for the digital storage of geographical data represented in the risk prevention plans (RPPs). The major risks consist of the eight main natural hazards foreseeable in the national territory: floods, earthquakes, volcanic eruptions, terrain movements, coastal hazards, avalanches, forest fires, cyclones and storms, and four technological risks: nuclear risk, industrial risk, risk of transport of hazardous materials and risk of dam failure. The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. The PPR tool is part of the Law of 22 July 1987 on the organisation of civil security, the protection of the forest against fire and the prevention of major risks. The development of a RPP is the responsibility 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: • Regulatory mapping translates into a geographical delimitation of the territory concerned by the risk. This delimitation defines areas in which specific regulations apply. These regulations are easement and impose requirements varying according to the hazard level to which the area is exposed. The areas are represented on a zoning plan that fully covers the study area. • The hazards at the origin of the risk are contained in hazard documents which may be inserted in the presentation report or annexed to the RPP. These documents are used to map the different intensity levels of each hazard considered in the risk prevention plan. • The issues identified during the preparation of the RPP can also be annexed 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 standardisation of PPR data have led COVADIS to opt for a single data standard, sufficiently generic to deal with the different types of risk prevention plan (PPRN natural risk prevention plans, technological risk prevention plans PPRT). This data standard does not consist of a complete modelling of a risk prevention plan dossier. The scope of this document is limited to geographical data in the RPPs, whether regulatory or not. Nor is the PPR standard intended to standardise knowledge of hazards. The challenge is to have a description for a homogeneous storage of the geographical data of the RPPs, since these data are of interest to several professions within the ministries responsible for agriculture, on the one hand, and ecology, and on the other hand, sustainable development.COVADIS风险预防计划数据标准涵盖了风险预防计划（Risk Prevention Plans, RPPs）中地理数据数字化存储所需的全部技术与组织规范。 该国境内可预见的主要风险包含八大类自然灾害与四大类技术风险：自然灾害分别为洪水、地震、火山喷发、地形变动、海岸灾害、雪崩、森林火灾以及气旋与风暴；技术风险则涵盖核风险、工业风险、危险物料运输风险以及堤坝溃决风险。 风险预防计划（PPR）由1995年2月2日发布的《加强环境保护法案》确立。该PPR工具属于1987年7月22日《民用安全组织、森林防火与重大风险预防法案》的组成部分。风险预防计划的编制主体为国家，最终审批决定由省长作出。 无论针对自然风险、技术风险还是多灾种，各类风险预防计划均具备共通特征，其信息内容可分为三大类别： • 监管制图：可明确划定受风险影响的地域范围。该范围界定了需适用特定监管要求的区域，此类规则带有地役权约束属性，并会依据区域面临的灾害等级设定差异化合规要求。相关区域将在全覆盖研究区域的分区规划图中予以标注。 • 风险源灾害信息：相关灾害文档可嵌入汇报报告或作为附件附于风险预防计划之后，此类文档用于绘制风险预防计划中所考量的各类灾害的不同强度等级分布图。 • 编制问题记录：在风险预防计划编制过程中识别出的问题，同样可通过地图形式作为附件附于已获批的计划文件中。 鉴于不同类型风险预防计划（PPR）之间存在上述共通性，同时为实现PPR数据的高水平标准化，COVADIS选择采用统一的数据标准——该标准具备足够的通用性，可适配各类风险预防计划，包括自然风险预防计划（PPRN）与技术风险预防计划（PPRT）。 该数据标准并非对风险预防计划档案的完整建模。 本文件的适用范围仅限于风险预防计划中的地理数据（无论是否属于监管类数据），且该PPR数据标准并非用于统一灾害相关知识的标准化规范。 当前面临的核心挑战在于，需为风险预防计划的地理数据构建统一的存储描述规范——此类数据同时受到农业、生态以及可持续发展领域的多个政府部门所关注。
