Simple download service (Atom) of the data package: Machilly Natural Hazard Prevention Plan (Haute-Savoie) — approved on 14/12/1998

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 process 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 data standard for risk prevention plans）涵盖了风险预防计划（Risk Prevention Plans，RPPs）中地理数据数字化存储的全部技术与组织规范。该国范围内可预见的重大风险包含8类主要自然灾害：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，以及4类技术风险：核风险、工业风险、危险物料运输风险与堤坝溃决风险。 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。而PPR工具则纳入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》的规制范畴。风险预防计划的编制主体为国家，由省长（Prefect）审批决定。 无论是自然风险、技术风险还是多灾种组合的风险预防计划，均具备共通特征，其内容包含三类信息： • 规制性制图：将风险覆盖的地域范围进行地理界定，该范围划定了适用特定规制的区域。此类规制为地役权限制，并根据区域面临的灾害等级设定差异化要求。上述区域以全覆盖研究区域的分区规划图进行可视化呈现。 • 风险源危害：风险的起源危害载于危害文件中，此类文件可纳入编制报告或作为RPP的附件。该类文件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。 • 风险预防计划编制过程中识别出的议题，亦可通过地图形式作为附件纳入获批后的正式文件。 不同类型PPR之间的共通性，以及提升PPR数据标准化水平的现实需求，促使COVADIS选择单一数据标准。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，PPRN）与技术风险预防计划（technological risk prevention plans，PPRT）。 本数据标准并非对风险预防计划卷宗的完整建模，其适用范围仅涵盖RPP中的地理数据，无论此类数据是否具有规制属性。此外，PPR标准亦无意实现灾害知识的标准化。本标准的核心目标是为RPP的地理数据提供统一的存储描述方案，因为此类数据对于农业、生态与可持续发展相关部委内的多个职业群体均具有应用价值。
