Simple download service (Atom) of the data package: Natural hazard prevention plan (PPRN) of the municipality of TAURIGNAN-CASTET

The COVADIS data standard for risk prevention plans includes all the technical and organisational specifications for the digital storage of geographical 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 natural, technological or multi-hazard, 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 (PPRN natural risk prevention plans, 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.

用于风险预防计划的COVADIS数据标准，涵盖了风险预防计划（Risk Prevention Plans，缩写RPPs）中所涉及地理数据的数字化存储所需的全部技术与组织规范。

该国境内可预见的主要风险包含8类自然灾害与4类技术风险：自然灾害包括洪水、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；技术风险涵盖核风险、工业风险、危险货物运输风险以及溃坝风险。

风险预防计划（PPR）由1995年2月2日《加强环境保护法案》确立。该PPR工具是1987年7月22日《民防组织、森林防火与重大风险预防法》的组成部分。风险预防计划的编制工作由国家负责，最终由省长审批敲定。

无论针对自然风险、技术风险还是多灾害风险，各类风险预防计划均具备共通性，其信息可分为三大类：
• 合规区划制图：可转化为风险所涉地域的地理边界划定。该边界明确了需适用特定管控要求的区域范围，此类管控规则属于限制性地役权范畴，并根据区域面临的灾害等级设定差异化约束条件。上述区域将在覆盖该研究全域的区划图中予以标注。
• 灾害源信息：引发风险的灾害源相关内容收录于灾害文档中，此类文档可嵌入风险预防计划的说明报告，或作为附件附于RPP之后。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区划图。
• 编制问题记录：风险预防计划编制过程中识别出的各类问题，也可通过地图形式作为附件附于已获批的官方文档中。

鉴于不同类型PPR之间的共通性，以及提升PPR数据标准化水平的需求，COVADIS选择采用单一数据标准——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）。

该数据标准并非对风险预防计划档案的完整建模。

本文件的适用范围仅限于RPPs中的地理数据（无论是否具备管控属性），且PPR标准亦并非用于统一灾害相关的专业知识。

当前面临的核心挑战在于，需为RPPs的地理数据制定统一的存储描述规范——这类数据受到负责农业、生态与可持续发展的部委内多个专业领域的关注与应用。
