Map Viewing Service (WMS) of the data batch: Flood risk prevention plan for the Tarco, Ciccollela and Taffunata watersheds

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: the nuclear risk, the industrial risk, the risk of transport of dangerous materials and the risk of dam failure.The risk prevention plans (PPR) were established by the Law 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 causing the risk are contained in hazard documents which can be inserted in the presentation report or annexed to the RPP.
These documents are used to map the different levels of intensity of each hazard taken into account in the risk prevention plan.• The issues identified during the development of the PPR can also be annexed to the approved document in the form of maps.These similarities between the different types of RPPs 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 (NRPP natural risk prevention plans, technological risk prevention plans PPRT)This data standard does not consist of a complete modelling of a risk 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 PPR geographical data, since these data are of interest to several professions within the ministries responsible for agriculture, on the one hand, and ecology, and sustainable development, on the other.

COVADIS数据标准（COVADIS Data Standard）针对风险预防计划（Risk Prevention Plans，以下简称RPPs）制定，涵盖了风险预防计划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：洪水、地震、火山喷发、地形位移、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、危险货物运输风险与坝体溃决风险。

风险预防计划（PPR）由1995年2月2日《加强环境保护法》确立。PPR工具隶属于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。风险预防计划的编制工作由国家主导，最终由省长审批决定。

无论风险类型为自然风险、技术风险还是多类型复合风险，各类风险预防计划均存在共通之处。其信息内容可分为三大类别：
• 监管制图：对受风险影响的领土范围进行地理划定，明确特定法规适用的区域范围。此类法规涉及地役权，并根据区域所面临的灾害等级设定差异化要求。上述区域将在覆盖整个研究区域的分区规划图中予以标注。
• 致险灾害信息：相关灾害内容收录于灾害文档中，可嵌入风险预防计划的演示报告，或作为附件附于计划之后。此类文档用于绘制风险预防计划所考量的各类灾害的不同强度等级分布图。
• 识别问题：在PPR编制过程中发现的问题，也可通过地图形式作为附件附于获批后的正式文件中。

不同类型RPPs之间的共通性，以及实现PPR数据标准化的需求，促使COVADIS选用单一数据标准。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，NRPPs）与技术风险预防计划（Technological Risk Prevention Plans，PPRTs）。

本数据标准并非对风险计划档案的完整建模。本文档的适用范围仅限于风险预防计划中的地理数据，无论其是否具备监管属性。此外，PPR标准亦无意实现灾害相关知识的标准化。

本次标准化工作的核心挑战在于为PPR地理数据的统一存储提供规范描述，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重要应用价值。
