Simple download service (Atom) of the data package: Natural hazard prevention plans (PPRN) in Ariège

This lot includes the assembly of data from Ariège’s Natural Risk Prevention Plans (NRPP) as of 27 April 2021. 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.

本批数据涵盖截至2021年4月27日的阿列日省（Ariège）自然风险预防计划（Natural Risk Prevention Plans, NRPP）相关数据汇编。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, RPP）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。

本数据集涵盖的重大风险包括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、地表移动、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、危险货物运输风险与溃坝风险。

风险预防计划（Risk Prevention Plans, PPR）由1995年2月2日《加强环境保护法案》制定。该PPR工具是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》的组成部分。RPP的编制由国家负责，最终由省长审批发布。

无论是自然风险、技术风险还是多灾害风险预防计划，均具备共通性，其信息可分为三类：
• 规制性制图：体现为风险涉及区域的地理划界。该划界划定了适用特定规制要求的区域，此类规制属于地役权类要求，并根据区域所面临的灾害等级设定差异化约束。上述区域在覆盖全部研究范围的分区规划图中予以标注。
• 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，此类文档可嵌入编制报告或作为附件附于RPP之后。文档用于标注风险预防计划中所考量的各类灾害的不同强度等级。
• 编制识别问题：RPP编制过程中识别出的相关问题，也可通过地图形式作为附件附于获批文件之后。

鉴于各类PPR之间的共通性，以及实现PPR数据标准化的需求，COVADIS选用了一套通用性足够强的单一数据标准，以适配不同类型的风险预防计划：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RPP中的地理数据（无论是否属于规制类数据），且该PPR标准并非旨在实现灾害相关知识的标准化。

当前面临的核心挑战在于，需为RPP地理数据的统一存储提供规范描述——此类数据一方面受到农业相关部委内多个专业领域的关注，另一方面亦为生态与可持续发展相关部委内的多个专业领域所关注。
