Data batch direct download service (WFS): Natural Risk Prevention Plan (PPRN) of the Granada-sur-l-Adour sector and -Larrivière-Saint-Savin — Landes (40)

The COVADIS Risk Prevention Plan Data Standard contains all the technical and organisational specifications for the digital storage of the spatial 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 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 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 (natural risk prevention plans PPRN, 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，简称RPP）所涉及空间数据的数字化存储所需的全部技术与组织规范。 主要风险涵盖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堤坝溃决风险。 风险预防计划（Risk Prevention Plans，简称PPR）依据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《民用安全组织、森林防火与重大风险预防法》的监管范畴。风险预防计划的编制主体为国家，最终审批权归省长（Prefect）所有。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。 此类计划包含三类核心信息： — 监管制图：即对受风险影响的领土进行地理划定，明确适用特定监管要求的区域范围。此类监管属于限制性规定，并根据区域面临的灾害等级设定差异化约束要求。上述区域通过完整覆盖研究区域的分区规划图进行可视化呈现。 — 风险源灾害信息：构成风险源头的灾害相关内容收录于灾害文档中，此类文档可嵌入汇报材料或作为风险预防计划的附件。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图谱。 — 编制问题记录：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获批后的正式文件中。 鉴于不同类型风险预防计划间存在上述共通特征，且业界期望实现风险预防计划数据的高水平标准化，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——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，其适用范围仅局限于风险预防计划中的地理数据（无论是否属于监管类地理数据）。同时，该风险预防计划标准亦无意对灾害认知体系进行标准化。 当前面临的核心挑战在于，需为风险预防计划的地理数据提供统一的存储描述标准——此类数据同时受到负责农业、生态与可持续发展的各部委内多个专业领域的关注。
