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

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。 该标准所覆盖的重大风险包含国家领土内可预见的八大主要自然灾害与四大技术风险：其中自然灾害为洪水、地震、火山喷发、地形变动、海岸灾害、雪崩、森林火灾、气旋与风暴；技术风险则包括核风险、工业风险、危险物料运输风险及堤坝溃决风险。 风险预防计划（PPR，Risk Prevention Plans）由1995年2月2日《加强环境保护法案》确立。该工具同时纳入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》的规制范畴。风险预防计划的编制工作由国家负责，最终由省长审批决定。 无论针对自然风险、技术风险还是多灾种，风险预防计划均具备共通性，其信息可分为三大类： • 规制绘图：即对风险所涉区域进行地理划定，明确适用特定规制的范围。此类规制属于地役权范畴，并根据区域所处的灾害风险等级设定差异化要求，相关区域在覆盖全部评估区域的分区规划图中予以标注。 • 风险源灾害信息：即风险成因的灾害相关内容，载于可纳入编制报告或作为RPP附件的灾害文档中。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。 • 编制过程中识别出的问题：也可通过地图形式作为附件并入已获批的RPP文件中。 鉴于各类PPR之间的共通性，以及提升PPR数据标准化水平的迫切需求，COVADIS最终选用单一数据标准——该标准具备足够的通用性，可适配不同类型的风险预防计划，包括自然风险预防计划（PPRN，Natural Risk Prevention Plans）与技术风险预防计划（PPRT，Technological Risk Prevention Plans）。 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涵盖RPP中的地理数据（无论是否属于规制类数据），且PPR数据标准并非用于统一灾害相关知识的标准化工作。 当前面临的核心挑战在于，需为RPP的地理数据构建统一的存储描述规范——此类数据同时受到负责农业、生态与可持续发展的政府部门内多个专业领域的关注。
