Map Viewing Service (WMS) of the data batch: Plan to prevent the foreseeable natural risks of flooding the Loire du Val d’Authion in Indre-et-Loire

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: the nuclear risk, the industrial risk, the risk of transport of dangerous materials and the risk of dam failure.The risk prevention plans (PPR) were established by the Law 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 they are natural, technological or multi-risk, 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 causing the risk are contained in hazard documents which can be inserted in the presentation report or annexed to the RPP. These documents are used to map the different levels of intensity of each hazard taken into account in the risk prevention plan.• The issues identified during the development 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 (NRPP natural risk prevention plans, technological risk prevention plans PPRT)This data standard does not consist of a complete modelling of a risk 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 PPR geographical data, since these data are of interest to several professions within the ministries responsible for agriculture, on the one hand, and ecology, and sustainable development, on the other.

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，RPPs）中所涉及地理数据的数字化存储所需的全部技术与组织规范。
该标准覆盖的主要风险包含本国境内可预见的八大自然灾害类别：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，以及四类技术风险：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PPR工具同时属于1987年7月22日《民用安全组织、森林防火与重大风险预防法》的组成部分。
单份风险预防计划（Risk Prevention Plan，RPP）的编制工作由国家主导，并由省长审批确定。
无论属于自然风险、技术风险还是多风险类型，各类风险预防计划均具备共通特征，其内容包含三类信息：
• 监管区划：将受风险影响的地域进行地理边界划定，明确适用专项法规的区域范围。此类法规属于地役权相关规定，并会依据区域所承受的灾害等级设定差异化要求。所有相关区域均会在覆盖整个研究区域的分区规划图中予以标注。
• 风险源文档：阐明引发风险的灾害类型，此类文档可嵌入汇报报告或作为附件附于RPP之后，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。
• 问题标识图件：在PPR编制过程中识别出的相关问题，也可通过图件形式作为附件附于获批文件之后。
鉴于不同类型RPP之间存在上述共通特征，且业界希望实现PPR数据的高水平标准化，COVADIS最终选择采用单一数据标准，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（Natural Risk Prevention Plans，NRPP）与技术风险预防计划（Technological Risk Prevention Plans，PPRT）。
本数据标准并非对风险计划档案的完整建模，其适用范围仅局限于RPP中的地理数据（无论是否属于监管类数据）。此外，PPR标准也并非用于统一灾害相关知识的标准化工作。
鉴于农业、生态与可持续发展相关部委内部的多个专业领域均需使用此类数据，本次工作的核心挑战在于为PPR地理数据的统一存储提供规范描述。
