Data batch direct download service (WFS): Oeyreluy 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风险预防计划数据标准（COVADIS Risk Prevention Plan Data Standard）涵盖了风险预防计划（Risk Prevention Plans，RPPs）中所呈现的空间数据的数字化存储所需的全部技术与组织规范。

该国领土内可预见的主要风险包含八大类自然灾害与四大类技术灾害：自然灾害涵盖洪水、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；技术灾害则包括核风险、工业风险、危险货物运输风险以及堤坝溃决风险。

风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《加强环境保护法案》确立。该工具同时隶属于1987年7月22日出台的《民用安全组织、森林防火与重大风险防治法》的规制范畴。风险预防计划的编制主体为国家，最终审批由省长作出。无论针对自然风险、技术风险还是综合风险，各类风险预防计划均存在共通之处。

风险预防计划包含三类信息：其一为管制制图，即对风险所涉领土进行地理界定。该界定明确了适用特定管制规则的区域范围，此类规则属于管制性地役权范畴，并根据区域面临的灾害等级设定差异化的义务标准。上述区域将在覆盖整个研究区域的分区规划图中予以标注。

其二为风险源灾害信息，相关内容收录于灾害文档中，此类文档可嵌入汇报报告或作为附件附于风险预防计划之后。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图。

其三为风险预防计划编制过程中识别出的问题，此类内容也可通过地图形式作为附件附于获批文件之后。

鉴于不同类型PPR之间的共通特性，以及实现PPR数据标准化的需求，COVADIS最终选择制定统一的数据标准，该标准具备足够的通用性，可适配各类风险预防计划，包括自然风险预防计划（PPRN）与技术风险预防计划（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（无论是否属于管制类数据）。此外，PPR数据标准亦无意对灾害认知进行标准化处理。

由于此类地理数据同时受到农业、生态与可持续发展等多部门的多个职业领域的关注，因此本标准的核心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规范。
