Data batch direct download service (WFS): Machilly Natural Hazard Prevention Plan — Foron (Haute-Savoie) — approved on 29/07/2011

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涵盖了风险预防计划（Risk Prevention Plans，简称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。该标准覆盖的重大风险包含本国境内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地面移动、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、危险物料运输风险以及溃坝风险。 风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日颁布的《加强环境保护法》确立，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》的规制范畴。RPP的编制工作由国家主导，并由省长（Prefect）审批决定。 无论针对自然风险、技术风险还是多灾种，风险预防计划均具备共通性，其信息主要包含三大类别： • 规制制图：即对受风险影响的地域范围进行地理界定，该范围明确了适用特定规制的区域。此类规制包含地役权要求，并根据区域面临的灾害等级设定差异化约束条件。上述区域将在覆盖全部研究范围的分区规划图中予以标注。 • 风险源灾害信息：即风险成因的灾害相关文档，可嵌入编制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分布图。 • 编制识别问题：在RPP编制过程中识别出的问题，也可通过地图形式作为附件附于获批后的RPP文件中。 鉴于不同类型PPR之间的共通性，以及对PPR数据实现高水平标准化的需求，COVADIS最终选用单一数据标准，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（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，其适用范围仅限定于RPP中的地理数据，无论此类数据是否属于规制范畴。此外，该标准亦不涉及灾害认知的标准化工作。本次标准制定的核心挑战在于，为RPP的地理数据实现统一存储提供规范描述——此类数据同时受到农业、生态与可持续发展等部门内多个专业领域的关注。
