Plan for the prevention of natural hazards (PPRN) of the municipality of Verniolle

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.面向风险预防计划的COVADIS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。 主要风险类型涵盖本国境内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地形运动、海岸灾害、雪崩、森林火灾、气旋与风暴，以及4类技术风险：核风险、工业风险、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《关于加强环境保护的法案》确立。该PPR工具隶属于1987年7月22日《关于民用安全组织、森林防火与重大风险预防的法案》。风险预防计划的制定由国家负责，并由省长审批实施。 无论是自然风险、技术风险还是多灾害类型的预防计划，均具备共通特征，其信息可分为三大类别： • 管制制图：对受风险影响的地域开展地理划定，明确适用特定管制要求的区域。此类管制为地役权管制，并依据区域所承受的灾害等级设定差异化约束要求。上述区域将在覆盖研究全域的分区规划图中进行标注。 • 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中，用于绘制本风险预防计划所考量的各类灾害的不同强度等级分布图。 • 编制识别问题：风险预防计划编制过程中识别出的各类问题，亦可通过地图形式作为附件附于已获批的正式文件中。 鉴于各类风险预防计划间的共通特性，以及对风险预防计划数据实现高水平标准化的诉求，COVADIS最终选用单一数据标准——该标准具备足够通用性，可适配全类型风险预防计划，包括自然风险预防计划（PPRN）与技术风险预防计划（PPRT）。 本数据标准并非针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，无论其是否属于管制范畴。同时，本PPR标准也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制定统一的存储描述规范——此类数据同时受到农业、生态与可持续发展相关部委内多个专业领域的关注。
