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

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，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。
本标准覆盖的主要风险包含法国本土可预见的8类主要自然灾害：洪水、地震、火山喷发、地形形变、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、危险货物运输风险与坝体溃决风险。
风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日《加强环境保护法案》确立，其作为管控工具隶属于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》。风险预防计划的编制工作由国家统筹负责，最终审批权归属于省长。
无论是自然风险、技术风险还是多灾种复合风险的预防计划，均具备共通特征，其信息可划分为三大类别：
• 合规制图：将风险覆盖区域的地理边界予以具象化划定。该边界界定了适用特定管制要求的区域，此类管制属于地役权范畴，并根据区域面临的灾害等级设定差异化约束。上述区域将在覆盖全部研究区域的分区规划图中予以标注。
• 风险源灾害信息：收录于专项灾害文档中，可嵌入计划编制报告，或作为附件附于风险预防计划之后。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。
• 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，附于获批后的风险预防计划文件中。
不同类型PPR之间的共通特征，以及提升PPR数据标准化水平的需求，促使COVADIS选用单一数据标准——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（Natural Risk Prevention Plans，简称PPRN）与技术风险预防计划（Technological Risk Prevention Plans，简称PPRT）。
该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RPPs中的地理数据（无论是否属于合规类数据），且PPR标准并非用于统一灾害相关知识的标准化体系。
当前面临的核心挑战在于，需为RPPs的地理数据构建统一的存储描述规范——此类数据同时受到农业、生态以及可持续发展领域相关部委内多个专业岗位的关注。
