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

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，RPPs）中所涉及地理数据的数字化存储相关所有技术与组织规范。
本标准所覆盖的重大风险包含本国领土内可预见的8类主要自然灾害：洪水、地震、火山喷发、地形异动、沿海灾害、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溃坝风险。
风险预防计划（PPR）由1995年2月2日《加强环境保护法》确立。该工具隶属于1987年7月22日颁布的《民用安全组织、森林防火与重大风险防治法》。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。
无论自然风险、技术风险还是多灾种风险，各类风险预防计划均存在共通特性，其信息可分为三大类：
• 管制区划制图：即对受风险影响的领土范围进行地理界定，明确特定规制条款适用的区域。此类规制属于地役性管制要求，并会依据区域所承受的灾害等级设定差异化约束条件。上述区域会在覆盖整个研究区域的分区规划图中予以标注。
• 风险源灾害信息：即风险成因的相关灾害内容，可纳入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。
• 编制识别问题：即风险预防计划编制阶段发现的各类问题，也可通过地图形式作为附件附于获批文件之后。
鉴于各类PPR之间存在共通特性，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（Natural Risk Prevention Plans，PPRN）与技术风险预防计划（Technological Risk Prevention Plans，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涵盖风险预防计划中的地理数据（无论是否属于管制类数据），且该PPR标准并非用于统一灾害相关知识的标准化规范。
当前面临的核心挑战在于，需针对风险预防计划的地理数据制定统一的存储描述规范——此类数据同时受到农业、生态与可持续发展等多个政府部门下属不同专业领域的关注。
