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

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.用于风险预防计划的COVADIS(COVADIS)数据标准，涵盖了风险预防计划（RPPs，Risk Prevention Plans）中地理数据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法国国土范围内可预见的8类主要自然灾害：洪水、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类技术风险：核风险、工业风险、危险物品运输风险与溃坝风险。 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，最终审批权归属省长。 无论是自然风险、技术风险还是多灾害风险类型的风险预防计划，均具备共通特征。其信息内容可划分为三大类别： • 规制性地图：将风险覆盖区域的地理边界进行具象化划定，明确适用特定规制的区域范围。此类规制属于限制性地役权条款，并会依据区域面临的灾害等级设定差异化约束要求。上述划定区域会在覆盖研究全域的分区规划图中予以标注。 • 风险源灾害信息：相关内容收纳于灾害文档中，此类文档可嵌入风险预防计划的编制说明报告，或作为附件附于计划之后。文档用于绘制风险预防计划所考量的各类灾害的不同强度等级分布图。 • 编制阶段识别出的相关问题：同样可通过地图载体，以附件形式附于已获批的风险预防计划文档中。 不同类型风险预防计划之间的共通特征，以及提升PPR数据标准化水平的行业需求，促使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，Natural Risk Prevention Plans）与技术风险预防计划（PPRT，Technological Risk Prevention Plans）。 本数据标准并非针对风险预防计划档案的完整建模。 本文件的适用范围仅限风险预防计划中的地理数据，无论该数据是否具备规制属性；同时，本PPR标准亦并非用于实现灾害相关知识的标准化。 当前面临的核心挑战是，为风险预防计划的地理数据构建统一的描述规范，以支撑其标准化存储——此类数据同时受到农业、生态及可持续发展领域相关部委内多个专业岗位的重视与使用需求。
