Data batch direct download service (WFS): Natural hazard prevention plan (PPRN) of the municipality of LISSAC

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.用于风险防范计划的COVADIS数据标准，涵盖了风险防范计划（Risk Prevention Plans，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。 该标准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：自然灾害包括洪涝、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；技术灾害则涵盖核风险、工业风险、危险货物运输风险以及堤坝溃决风险。 风险防范计划（Risk Prevention Plans，PPR）由1995年2月2日发布的《加强环境保护法案》确立。该工具同时隶属于1987年7月22日发布的《民用安全组织、森林防火与重大风险预防法案》的规制范畴。风险防范计划的编制工作由国家负责，最终审批权归属省长。 无论针对自然灾害、技术灾害还是复合型灾害，各类风险防范计划均存在共通之处，其信息内容可分为三大类别： • 规制制图：即对受风险影响的领土范围进行地理界分。该界分明确了适用特定规制的区域范围，此类规制属于地役权范畴，会依据区域所承受的灾害等级设定差异化约束要求。上述区域会在全覆盖研究区域的分区制图中予以呈现。 • 风险源灾害信息：即阐释风险成因的灾害文档，此类文档可嵌入编制报告或作为附件附于风险防范计划之后，用于绘制风险防范计划中所考量的各类灾害的不同强度等级分布图。 • 编制问题相关信息：即在风险防范计划编制过程中识别出的各类问题，同样可通过制图形式作为附件附于获批文件之后。 鉴于不同类型风险防范计划之间的共通特性，以及提升PPR数据标准化水平的需求，COVADIS最终选用了一套通用性足够强的单一数据标准，以适配各类风险防范计划——包括自然灾害风险防范计划（PPRN）与技术灾害风险防范计划（PPRT）。 该数据标准并非对风险防范计划卷宗的完整建模。 本文件的适用范围仅局限于风险防范计划中的地理数据（无论是否属于规制类地理数据），且该PPR数据标准并非用于统一灾害相关知识的标准化规范。 当前面临的核心挑战在于，为风险防范计划的地理数据构建统一的存储描述规范——此类数据同时受到负责农业、生态以及可持续发展的政府部门内多个专业领域的关注。
