Data batch direct download service (WFS): Plan for the prevention of natural hazards (PPRN) of the municipality of VILLENEUVE-D’Olmes

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，简称RPPs）中所涉及地理数据的数字化存储所需的全部技术与组织规范。 该标准覆盖的重大风险包含本国领土内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地形位移、海岸灾害、雪崩、森林火灾、气旋与风暴；以及4类技术灾害：核事故风险、工业事故风险、危险货物运输风险与堤坝溃决风险。 风险预防计划（PPR）由1995年2月2日《加强环境保护法》确立。该工具同时纳入1987年7月22日《民防组织、森林防火与重大风险预防法》的规制范畴。风险预防计划的编制主体为国家，最终审批权由省长行使。 无论针对自然灾害、技术灾害还是多灾害复合型风险，各类风险预防计划均具备共通性，其包含三类核心信息： • 规制性制图：通过地理区划明确受风险影响的领土范围，该区划界定了适用特定规制的区域。此类规制属于土地使用限制条款，其要求将根据区域面临的灾害风险等级动态调整。上述区划将以覆盖全部研究区域的分区规划图形式呈现。 • 风险源灾害信息：相关灾害文档可嵌入编制说明报告或作为附件附于风险预防计划后，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区划图。 • 编制识别问题信息：在风险预防计划编制过程中识别出的各类问题，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）间的共通性，以及提升PPR数据标准化水平的需求，COVADIS最终选用单一数据标准——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）。 本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局限于风险预防计划中的地理数据（无论是否属于规制类数据），且该PPR数据标准并非用于统一灾害认知的标准化规范。 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、生态与可持续发展等领域的多个政府部门关注。
