Data batch direct download service (WFS): Flood risk prevention plan in the Porto catchment area

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风险防控计划数据标准涵盖了风险防控计划（Risk Prevention Plans，RPPs）中地理数据数字化存储所需的全部技术与组织规范。该国国土范围内可预见的主要风险包含8类主要自然灾害与4类技术灾害：自然灾害包括洪水、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；技术灾害则涵盖核风险、工业风险、危险物料运输风险以及溃坝风险。

风险防控计划（PPR）由1995年2月2日《加强环境保护法》制定。而PPR工具则隶属于1987年7月22日《关于组织民防、森林防火与重大风险防控的法律》。风险防控计划的编制工作由国家负责，且由省长作出审批决定。

无论风险类型为自然灾害、技术灾害还是多风险类型，各类风险防控计划均存在共通之处，其包含三类信息：
1. 管控区划：将受风险影响的领土范围以地理边界形式划定，该边界明确了需适用特定管控要求的区域。此类管控要求属于限制性使用约束，且需根据区域所承受的灾害等级制定差异化标准。上述区域将在全覆盖研究区域的区划图中予以标注。
2. 灾害详情：相关风险的致灾因子收录于灾害文档中，此类文档可嵌入陈述报告，或作为附件附于风险防控计划之后。该类文档用于绘制风险防控计划中所考量的各类灾害的不同强度等级区划图。
3. 识别问题：在PPR编制过程中发现的相关问题，也可通过地图形式作为附件附于获批文件之后。

不同类型风险防控计划之间的共通性，以及实现PPR数据标准化水平的诉求，促使COVADIS选择采用单一数据标准。该标准具备足够的通用性，可适配各类风险防控计划，包括自然风险防控计划（Natural Risk Prevention Plans，NRPP）与技术风险防控计划（Technological Risk Prevention Plans，PPRT）。

本数据标准并非对风险计划档案的完整建模，本文档的适用范围仅局限于风险防控计划中的地理数据，无论其是否属于管控类地理数据。同时，PPR标准亦无意实现灾害相关知识的标准化。

当前面临的挑战在于，需为PPR地理数据提供统一的存储描述规范——此类数据同时受到农业、生态与可持续发展等领域的多个政府部门的关注与使用。
