Data batch direct download service (WFS): Flood risk prevention plan for the Tarco, Ciccollela and Taffunata watersheds — partial revision

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.

用于风险预防计划的COVADIS数据标准，涵盖了风险预防计划（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、地表移动、海岸灾害、雪崩、森林火灾、飓风与风暴；以及四大技术风险：核风险、工业风险、危险货物运输风险以及堤坝溃决风险。

风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日《加强环境保护法》确立。该PPR工具同时纳入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由国家负责，最终审批权归属省长。

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具备共通性，其内容包含三大类信息：
• 监管区划制图：指对受风险影响的领土范围进行地理边界划定。该边界明确了适用特定监管要求的区域范围，此类监管规则属于地役权范畴，并根据区域面临的灾害风险等级设定差异化的合规要求。上述区域将在完全覆盖研究区域的分区规划图中予以标注。
• 致险灾害信息：相关灾害详情载于灾害文档中，此类文档既可嵌入风险预防计划的汇报报告，也可作为附件附于计划之后。这些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区划。
• 编制问题记录：在风险预防计划编制过程中识别出的相关问题，也可通过地图形式作为附件附于获批后的计划文件中。

鉴于不同类型风险预防计划之间的共通特性，以及实现PPR数据高质量标准化的需求，COVADIS最终选用单一数据标准——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，涵盖自然风险预防计划（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风险预防计划中的地理数据（无论是否属于监管类数据）。此外，该PPR标准也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，如何构建适配PPR地理数据同质化存储的描述规范——此类数据同时受到负责农业、生态与可持续发展的政府部门内多个专业领域的关注。
