Data batch direct download service (WFS): Plan for the prevention of natural hazards (PPRN) of the municipality of ORNOLAC-USSAT-LES-BAINS

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（risk prevention plans，RPPs）数据标准，涵盖了风险预防计划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本土可预见的8类主要自然灾害与4类技术灾害：前者包括洪水、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；后者涵盖核风险、工业风险、危险物料运输风险以及堤坝溃决风险。
风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日《加强环境保护法案》制定，同时该工具也是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》的组成部分。风险预防计划的编制由国家负责，由省长审批决定。
无论属于自然灾害、技术灾害还是多灾害类型，风险预防计划均具有共通特征，其内容包含三类信息：
• 规制性地图（Regulatory mapping）：将受风险影响的地域进行地理划定，明确特定规制条款适用的区域。此类规制为限制性地役权，并根据区域面临的灾害等级设定差异化要求，相关区域将在全覆盖研究区域的分区规划图中予以标注。
• 灾害源信息：风险的成因灾害收录于灾害文档中，此类文档可嵌入汇报文本或作为风险预防计划的附件，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。
• 问题梳理信息：在风险预防计划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文件中。
鉴于各类风险预防计划存在上述共通性，同时为实现PPR数据的高水平标准化，COVADIS选择采用一套通用性足够强的单一数据标准，以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，PPRN）与技术风险预防计划（technological risk prevention plans PPRT）。
该数据标准并非对风险预防计划卷宗的完整建模。本文件的适用范围仅限于风险预防计划中的地理数据，无论其是否具备规制属性。同时，本PPR标准也并非旨在统一灾害相关知识。
当前面临的核心挑战在于，为风险预防计划的地理数据提供统一的存储描述标准——此类数据同时受到农业、生态与可持续发展相关部委下辖的多个专业领域的关注。
