Map Viewing Service (WMS) of the data batch: Natural Risk Prevention Plan (NRPP) of Gousse — 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风险防控计划数据标准》涵盖了风险防控计划（Risk Prevention Plans, RPPs）中空间数据数字化存储所需的全部技术与组织规范。

该国可预见的重大风险包含8类主要自然灾害与4类技术灾害：8类自然灾害分别为洪水、地震、火山喷发、地形变形、海岸灾害、雪崩、森林火灾、气旋与风暴；4类技术灾害分别为核风险、工业风险、危险物料运输风险以及堤坝溃决风险。

风险防控计划（PPR）由1995年2月2日《加强环境保护法案》确立，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防控法案》的规制范畴。风险防控计划（RPP）的编制主体为国家，最终由省长审批。无论针对自然风险、技术风险还是多风险，各类风险防控计划均存在共通特性。

此类计划包含三类信息：
— 管控制图：即对受风险影响的领土进行地理划界，明确特定规制条款适用的区域范围。此类规制为管制性地役权，其约束要求随区域面临的灾害等级不同而有所差异。上述区域将通过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：相关灾害文档可嵌入编制报告或附于风险防控计划（RPP）之后，用于标注风险防控计划中所考量的各类灾害的不同强度等级分布。
— 编制过程中识别出的问题信息：此类信息也可通过地图形式附于获批后的风险防控计划文件中。

鉴于不同类型风险防控计划的共通特性，以及提升风险防控计划数据标准化水平的需求，COVADIS最终选用单一数据标准。该标准具备足够的通用性，可适配各类风险防控计划，包括自然风险防控计划（PPRN）与技术风险防控计划（PPRT）。

本数据标准并非对风险防控计划卷宗的完整建模，其适用范围仅涵盖风险防控计划（RPPs）中的地理数据，无论此类数据是否属于管控类地理数据。同时，该标准也并非用于统一灾害相关知识的标准化规范。

当前面临的核心挑战在于，需为风险防控计划（RPPs）的地理数据提供统一的存储规范，因为此类数据分别受到农业、生态及可持续发展领域的多个政府部门的关注。
