Data batch direct download service (WFS): Plan to prevent the foreseeable natural risks of flooding the Indre Valley 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.COVADIS风险预防计划数据标准（COVADIS data standard）涵盖了风险预防计划（Risk Prevention Plans，简称RPPs）中所承载地理数据的数字化存储所需的全部技术与组织规范。该国主要风险包含本国领土内可预见的8类自然灾害与4类技术风险：前者包括洪涝、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；后者涵盖核风险、工业风险、危险货物运输风险以及溃坝风险。 风险预防计划（PPR，Risk Prevention Plans）系依据1995年2月2日颁布的《加强环境保护法》制定。PPR工具则纳入1987年7月22日《民用安全组织、森林防火与重大风险预防法》的规制范畴。风险预防计划的编制主体为国家，最终审批权由省长行使。 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存在共性，其包含三类信息： • 监管制图即对风险覆盖区域进行地理界定，明确适用特定规制的区域范围。此类规定具有地役权属性，并根据区域所面临的灾害等级设定差异化要求。上述区域以覆盖研究区域的分区图进行呈现。 • 致险灾害相关内容收录于灾害文档中，此类文档可嵌入编制报告或作为附件附于风险预防计划之后，用于绘制风险预防计划中考量的各类灾害的不同强度等级分布图。 • 风险预防计划编制过程中识别出的相关问题，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间的共性，以及对PPR数据实现高水平标准化的诉求，COVADIS最终选用单一数据标准，该标准具备足够通用性，可适配各类风险预防计划的处理需求，包括自然风险预防计划（Natural Risk Prevention Plans，简称NRPP）与技术风险预防计划（Technological Risk Prevention Plans，简称PPRT）。 本数据标准并非对风险计划档案的完整建模，其适用范围仅涵盖风险预防计划中的地理数据（无论是否属于监管范畴）。此外，PPR标准亦未旨在实现灾害相关知识的标准化。 当前面临的核心挑战在于构建一套可实现PPR地理数据统一存储的描述规范，因为此类数据同时受到负责农业、生态与可持续发展的部委内多个专业领域的关注。
