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

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，缩写RPPs）中所呈现的地理数据的数字化存储所需的全部技术与组织规范。 该标准覆盖的主要风险包含本国境内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地形变动、海岸带灾害、雪崩、森林火灾、气旋与风暴；以及4类技术风险：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，Risk Prevention Plans）由1995年2月2日《加强环境保护法案》确立。该工具同时隶属于1987年7月22日《民防组织、森林防火与重大风险防治法》的规制范畴。风险预防计划（RPP）的编制主体为国家，最终审批决定权归属省长。 无论是自然风险、技术风险还是复合型灾害风险的预防计划，均具备共通的信息结构，可划分为三类信息： • 管控区划制图：即对风险覆盖的辖区进行地理界域划定，明确特定管控规则适用的区域范围。此类规则为地役权类管控要求，并根据区域面临的灾害等级设定差异化约束条件。上述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编制说明报告或附于风险预防计划（RPP）之后，此类文档用于标注风险预防计划中所考量的各类灾害的不同强度等级分布。 • 编制过程中识别出的相关问题，亦可通过制图形式附于获批后的风险预防计划文件中。 鉴于各类风险预防计划（PPR）间的共通特性，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，可适配不同类型的风险预防计划，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（RPPs）中的地理数据，无论其是否为管控类地理数据。同时，该PPR标准亦未旨在实现灾害认知的标准化。 当前面临的核心挑战在于，需为风险预防计划（RPPs）的地理数据提供统一的描述规范，以适配农业、生态与可持续发展等多个政府部门内不同专业领域的使用需求。
