Map Viewing Service (WMS) of the data batch: Tethieu Natural Risk Prevention Plan (NRPP) — 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（COVADIS Risk Prevention Plan Data Standard）涵盖了风险防控计划（Risk Prevention Plans, RPPs）中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。

该标准覆盖的主要风险类型包含本国境内可预见的8类主要自然灾害：洪水、地震、火山喷发、地面移动、海岸带灾害、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、危险物料运输风险及堤坝溃决风险。

风险防控计划（PPR）由1995年2月2日发布的《加强环境保护法案》确立。该PPR工具同时纳入1987年7月22日发布的《民用安全组织、森林防火与重大风险防控法案》框架之中。风险防控计划（RPP）的编制工作由国家负责，由省长最终审批。无论是自然风险、技术风险还是多风险防控计划，均具备共通特征。

此类计划包含三类核心信息：
— 合规制图：将风险覆盖区域的地理边界进行具象化界定，明确特定法规适用的管辖范围。此类管辖范围内需遵守地役权相关规定，并根据区域面临的灾害等级执行差异化管控要求。上述区域将通过全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：收录于灾害文档中，此类文档可嵌入计划汇报文本，或作为附件附于风险防控计划之后。文档用于绘制风险防控计划中所考量的各类灾害的不同强度等级分布地图。
— 编制过程中识别出的问题：同样可通过地图形式作为附件，附于已获批的风险防控计划文档中。

鉴于不同类型PPR之间的共通特征，以及提升PPR数据标准化水平的需求，COVADIS选用了一套通用化程度足够高的单一数据标准，以适配各类风险防控计划——包括自然风险防控计划（Natural Risk Prevention Plans, PPRN）与技术风险防控计划（Technological Risk Prevention Plans, PPRT）。

本数据标准并非对风险防控计划档案的完整建模，其适用范围仅涵盖风险防控计划中的地理数据（无论是否合规相关）。同时，本PPR标准也并非用于规范灾害相关知识的标准化工作。

当前面临的核心挑战在于，需构建一套统一的描述规范以实现风险防控计划地理数据的同质化存储——此类数据同时受到农业、生态及可持续发展等领域多个部委下属专业部门的关注。
