Simple download service (Atom) of the data package: 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风险预防计划数据标准（COVADIS Risk Prevention Plan Data Standard）包含了风险预防计划（Risk Prevention Plans，以下简称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。

该标准所覆盖的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、地形移动、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溃坝风险。

风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日《加强环境保护法案》制定。PPR工具隶属于1987年7月22日《关于组织民防、森林防火与重大风险预防的法律》。风险预防计划的编制由国家负责，最终审批由省长作出。无论风险类型为自然风险、技术风险还是多风险，各类风险预防计划均存在共通特性。

此类计划包含三类信息：
— 规制性地图：对受风险影响的领土进行地理界分，该界分明确了适用特定规制的区域范围。此类规制以地役权为核心，并根据区域所面临的灾害等级设定差异化要求。上述区域会在全覆盖研究区域的分区规划图上予以标注。
— 致灾因子信息：引发风险的灾害源信息收录于灾害文档中，此类文档可嵌入汇报材料或作为RPP的附件。此类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。
— 编制识别问题：在RPP编制过程中发现的相关问题，同样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存在上述共通特性，同时为实现PPR数据的高水平标准化，COVADIS选择采用单一数据标准。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（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RPPs中的地理数据，无论该数据是否具有规制属性。此外，PPR标准亦无意对灾害相关知识进行标准化。

当前面临的核心挑战在于，需为RPPs的地理数据提供统一的存储描述方案——此类数据同时受到农业、生态以及可持续发展等领域的多个政府部门的关注。
