Data batch direct download service (WFS): Plan for the prevention of natural hazards (PPRN) of the municipality of SAINT-JEAN-DE-VERGES

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.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，简称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、地形变动、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、危险物料运输风险与溃坝风险。 风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日《加强环境保护法案》制定。该工具同时纳入1987年7月22日《民防组织、森林防火与重大风险防控法》的规制范畴。风险预防计划的编制职责由国家承担，最终审批权归属省长。 无论自然风险、技术风险还是多灾害风险的预防计划，均具备共通特征。其信息可分为三大类别： • 规制性地图：明确划定风险所涉领土的地理边界，该边界界定了适用特定规制的区域。此类规制属于地役权性质，并会根据区域面临的灾害等级调整相关要求。上述区域将在全覆盖研究区域的分区规划图中予以标注。 • 灾害源信息：引发风险的灾害相关内容收录于灾害文档中，此类文档可纳入编制报告或作为RPP的附件。这些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地图。 • 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纳入获批文件。 不同类型风险预防计划之间的共通性，以及提升PPR数据标准化水平的需求，促使COVADIS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，包括自然风险预防计划（natural risk prevention plans，简称PPRN）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预防计划档案的完整建模。本文档的适用范围仅局限于风险预防计划中的地理数据（无论是否属于规制性内容），且该标准亦无意对灾害认知进行标准化。 当前面临的挑战在于，为风险预防计划的地理数据提供统一的存储描述方案——此类数据同时受到农业、生态与可持续发展相关部委内多个专业领域的关注。
