Natural hazard prevention plan of Monnetier-Mornex — Arve (Haute-Savoie) — approved on 19/11/2001

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数据标准（COVADIS data standard）面向风险预防计划，涵盖了风险预防计划（RPP，Risk Prevention Plans）中地理数据数字化存储的全部技术与组织规范。其覆盖的重大风险包含本国领土内可预见的8类主要自然灾害与4类技术灾害：自然灾害为洪涝、地震、火山喷发、地形形变、海岸灾害、雪崩、森林火灾、气旋与风暴；技术灾害则涵盖核风险、工业风险、危险物料运输风险以及溃坝风险。 风险预防计划（PPR，Risk Prevention Plans）由1995年2月2日发布的《加强环境保护法案》确立。PPR工具同时纳入1987年7月22日发布的《民用安全组织、森林防火与重大风险防治法案》的规制范畴。风险预防计划的编制工作由国家主导，最终由省长审批敲定。 无论针对自然灾害、技术灾害还是多灾害类型，风险预防计划均具有共通性，其包含三类信息： 1. 规制性测绘：将受风险影响的领土范围以地理边界形式划定，明确特定规制适用的区域。此类规制为地役性要求，并根据区域面临的灾害等级设定差异化约束。上述区域会通过全覆盖研究区域的分区规划图予以呈现。 2. 灾害源文件：承载引发风险的灾害相关信息，可嵌入编制说明报告或作为风险预防计划的附件。此类文件用于标注风险预防计划中考量的各类灾害的不同强度等级分布。 3. 识别问题图集：在风险预防计划编制过程中识别出的问题，也可通过地图形式附于已获批的正式文件中。 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，推动COVADIS选择统一的数据标准——该标准具备足够的通用性，可适配各类风险预防计划的处理需求，包括自然风险预防计划（PPRN，Natural Risk Prevention Plans）与技术风险预防计划（PPRT，Technological Risk Prevention Plans）。 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风险预防计划中的地理数据（无论是否具备规制属性）。同时，该PPR标准亦无意统一灾害相关知识的表述。本次工作的核心目标，是为风险预防计划的地理数据提供统一的存储描述方式，因为此类数据同时受到农业、生态与可持续发展相关部委内多个专业领域的关注。
