Data batch direct download service (WFS): Natural risk prevention plan for Vitry-le-François flooding on the Saulx sector (department de la Marne)

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 for risk prevention plans）涵盖了风险预防计划（risk prevention plans, RPPs）中所表征地理数据的数字化存储所需的全部技术与组织规范。其覆盖的主要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。该风险预防计划工具隶属于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主体为国家，最终由行政长官（Prefect）审批确定。 无论是自然风险、技术风险还是多风险类型的风险预防计划，均具备共通特征。其包含三类信息： • 规制性测绘成果：该类成果对受风险影响的领土范围进行地理界分，明确特定监管规则的适用范围。此类规制带有地役权限制，并依据区域所面临的灾害等级设定差异化要求。上述区域将在全覆盖研究区域的分区规划图中予以标注。 • 致灾因子信息：相关致灾内容收录于灾害文档中，可嵌入风险预防计划的展示报告，或作为附件附于计划之后。此类文档用于绘制风险预防计划所考量的各类灾害的不同强度等级分布图。 • 问题梳理成果：在风险预防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已获批的计划文件中。 鉴于不同类型风险预防计划之间存在上述共通特征，同时为实现风险预防计划数据的高水平标准化，COVADIS选择采用统一的数据标准——该标准具备足够的通用性，可适配各类风险预防计划的处理需求，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。本文件的适用范围仅限于风险预防计划中的地理数据，无论其是否具备规制属性。同时，本标准亦无意对灾害认知进行标准化。 当前面临的挑战在于，需为风险预防计划地理数据的统一存储提供规范描述——此类数据一方面受农业相关部委多个专业领域关注，另一方面也受到生态与可持续发展领域相关部门的重视。
