Data batch direct download service (WFS): Natural Risk Prevention Plan (PPRN) of the municipality of PERLES-ET-CASTELET

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数据标准，涵盖了风险预防计划（Risk Prevention Plans，以下简称RPPs）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本国领土内可预见的八大自然灾种：洪水、地震、火山喷发、地面位移、海岸带灾害、雪崩、森林火灾、气旋与风暴；以及四大技术风险类型：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（Risk Prevention Plans，简称PPR）由1995年2月2日发布的《加强环境保护法案》确立。该PPR工具同时隶属于1987年7月22日颁布的《公共安全组织、森林防火与重大风险预防法》。单份RPP的编制工作由国家主导，最终由省长签署敲定。 无论针对自然风险、技术风险还是多类型复合风险，各类风险预防计划均存在共通之处，其信息内容可分为三大类别： • 合规性制图：明确风险覆盖区域的地理边界，划定适用特定监管要求的范围。此类监管要求为行政地役权，且会根据区域面临的灾害等级设定差异化约束标准。相关区域会在完全覆盖研究区域的区划图中予以标注。 • 风险源灾害信息：针对风险源灾害所形成的文档，既可嵌入RPP的编制汇报材料，也可作为附件附于RPP之后。此类文档用于绘制风险预防计划中各灾种的不同强度等级空间分布图谱。 • 编制过程中识别出的相关问题，也可通过地图形式作为附件附于获批后的RPP文档中。 鉴于不同类型PPR存在上述共通特性，且业界期望实现PPR数据的高水平标准化，COVADIS最终选用单一数据标准——该标准具备足够通用性，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）。 本数据标准并非针对风险预防计划档案的完整建模方案。 本文件的适用范围仅局限于RPPs中的地理数据（无论是否具备合规属性），且该PPR标准亦并非旨在统一灾害相关知识的标准化表述。 当前核心挑战在于，需为RPPs的地理数据实现同质化存储制定统一描述规范——此类数据同时受到农业、生态与可持续发展领域多个政府部门相关从业者的关注。
