Map Viewing Service (WMS) of the data batch: Tarnos Natural Risk Prevention Plan (NRPP) — Landes (40)

The COVADIS Risk Prevention Plan Data Standard contains all the technical and organisational specifications for the digital storage of the spatial 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 they are natural, technological or multi-risk, 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 (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 Risk Prevention Plan Data Standard）涵盖了风险预防计划（Risk Prevention Plans，以下简称RPPs）中所呈现空间数据的数字化存储所需的全部技术与组织规范。 该标准覆盖的主要风险包含本国境内可预见的8类主要自然灾害：洪水、地震、火山喷发、地形移动、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、危险货物运输风险以及溃坝风险。 风险预防计划（以下简称PPR）由1995年2月2日发布的《加强环境保护法案》确立。该PPR工具是1987年7月22日《民间安全组织、森林防火与重大风险预防法》的组成部分。风险预防计划的编制工作由国家负责，最终由省长审批决定。无论风险类型为自然风险、技术风险还是综合多风险，各类风险预防计划均存在共通之处。 风险预防计划包含三类信息： 其一为规制性测绘，即对风险涉及的领土范围进行地理划定。该划定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，并根据区域所面临的灾害等级设定差异化约束要求。上述区域将在完整覆盖研究范围的分区规划图中予以标注。 其二为风险源灾害信息，即收录于灾害文档中的风险成因。此类文档可嵌入风险预防计划的编制报告，或作为附件附于RPP之后，用于绘制风险预防计划中涉及的各类灾害的不同强度等级分布图。 其三为风险预防计划编制过程中识别出的问题，此类问题也可通过地图形式作为附件附于已获批的风险预防计划文档中。 鉴于不同类型PPR之间的共通特性，以及对PPR数据实现高水平标准化的需求，COVADIS最终选择制定统一的数据标准。该标准具备足够的通用性，可适配各类风险预防计划，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，其适用范围仅局限于风险预防计划中的地理数据（无论是否属于规制性地理数据）。此外，该PPR数据标准也并非用于实现灾害相关知识的标准化。 当前面临的核心挑战在于，需为风险预防计划的地理数据制定统一的存储描述规范——此类数据同时受到农业、生态以及可持续发展等多个主管部门内的多个专业领域的关注。
