Data batch direct download service (WFS): Natural Risk Prevention Plan (PPRN) Tarn Flood downstream of Albi — Tarn

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 PPR can also be annexed to the approved document in the form of maps.These similarities between the different types of RPPs 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 process the different types of risk prevention plan (NPPRN 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风险预防计划（Risk Prevention Plans，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日颁布的《加强环境保护法令》确立。
PPR工具是1987年7月22日《民用安全组织、森林防火与重大风险预防法》的组成部分。风险预防计划（RPP）的编制工作由国家负责，最终由省长审批决定。
无论自然风险、技术风险还是多灾害类型，各类风险预防计划均存在共通之处。
它们包含三类信息：
• 法规管控区划是对风险覆盖的领土范围进行地理界定。该界定范围明确了需适用特定规制要求的区域：此类规制为地役性约束，并依据区域所处的灾害风险等级设定差异化合规要求。上述区域将在全覆盖研究区域的分区规划图中予以标注。
• 风险成因灾害信息收录于灾害文档中，此类文档可嵌入风险预防计划的汇报报告，或作为附件附于RPP之后。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区划图。
• PPR编制过程中识别出的各类问题，亦可通过地图形式作为附件附于获批文件之后。
鉴于不同类型RPP间的共通性，以及实现PPR数据标准化水平的需求，COVADIS最终选择采用单一数据标准——该标准具备足够的通用性，可适配各类风险预防计划（全国自然风险预防计划NPPRN、技术风险预防计划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RPP中的地理数据（无论是否属于法规管控范畴），且PPR数据标准亦并非用于实现灾害认知的标准化。
当前面临的核心挑战在于，为RPP的地理数据实现同质化存储提供统一描述规范——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。
本标准于2015年8月18日获批。
