Map Viewing Service (WMS) of the data batch: Flood risk prevention plan in the STABIACCIU Valley — amended

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风险预防计划数据标准涵盖了风险预防计划（Risk Prevention Plans，RPPs）中所呈现的地理数据的数字化存储所需的全部技术与组织规范。其涵盖的主要风险包含本国领土内可预见的八大类自然灾害：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；以及四类技术风险：核事故风险、工业事故风险、危险货物运输风险与堤坝溃决风险。

风险预防计划（PPR）由1995年2月2日《加强环境保护法》确立，而PPR工具则纳入1987年7月22日《民防组织、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，最终审批权归属于省长。

无论针对自然风险、技术风险还是复合型风险，各类风险预防计划均存在共通特性，其信息主要包含三大类别：
• 管制区划：即对受风险影响的地域范围进行地理界定。该界定明确了适用特定管制规则的区域，此类规则属于管制地役权范畴，并根据区域承受的灾害等级设定差异化合规要求。上述区域将在覆盖全研究区域的分区规划图中予以标注。
• 灾害源信息：承载风险成因的灾害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。
• 编制问题记录：PPR编制过程中识别出的各类问题，也可通过地图形式作为附件附于获批文件之后。

鉴于各类RPP间存在上述共通特性，且PPR数据亟需实现较高水平的标准化，COVADIS最终选用单一数据标准——该标准具备足够通用性，可适配不同类型的风险预防计划，包括自然风险预防计划（Natural Risk Prevention Plans，NRPP）与技术风险预防计划（Technological Risk Prevention Plans，PPRT）。

本数据标准并非对风险计划档案的完整建模，其适用范围仅局限于RPP内的地理数据（无论是否属于管制范畴）。此外，PPR标准亦不旨在实现灾害相关知识的标准化。

当前核心挑战在于，需形成一套统一的PPR地理数据存储描述规范——此类数据同时受到农业、生态与可持续发展领域相关部委内多个职业岗位的关注。
