Map Viewing Service (WMS) of the data batch: Dax — Landes Natural Risk Prevention Plan (NRPP) (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，以下简称RPPs，又称PPR）中所呈现空间数据的数字化存储所需的全部技术与组织规范。
本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、地面形变、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、危险货物运输风险与坝体溃决风险。
风险预防计划由1995年2月2日《加强环境保护法案》确立。而PPR工具则隶属于1987年7月22日《民用安全组织、森林防火与重大风险预防法案》。
风险预防计划的编制主体为国家，最终决策由省长（Prefect）作出。无论风险类型为自然风险、技术风险还是复合型风险，各类PPR均具备共通特征。
此类计划包含三类核心信息：
— 监管区划制图：即对受风险影响的领土进行地理界定。该界定明确了适用特定监管要求的区域，此类监管属于限制性地役权管制，并根据区域面临的灾害等级设定差异化要求。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。
— 灾害源信息：风险的源头灾害收录于灾害专题文档中，此类文档可嵌入编制报告或作为附件纳入RPP。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。
— RPP编制过程中识别出的问题，也可通过地图形式作为附件纳入已获批的正式文件。
鉴于不同类型PPR间存在上述共性，同时为实现PPR数据的高水平标准化，COVADIS最终采用单一数据标准，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，其适用范围仅涵盖RPP中的地理数据，无论此类数据是否具备监管属性。此外，本PPR标准亦无意对灾害认知进行标准化。
当前面临的核心挑战在于，需为RPP的地理数据构建统一的存储方案——此类数据同时受到农业、生态与可持续发展等领域相关部委内多个业务领域的关注。
