Data batch direct download service (WFS): Plan for the prevention of natural hazards (PPRN) of the municipality of PRADES

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: 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 natural, technological or multi-hazard, 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 (PPRN natural risk prevention plans, 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 data standard for risk prevention plans）涵盖了风险预防计划（Risk Prevention Plans，简称RPP）中所涉及地理数据数字化存储的全部技术与组织规范。
主要风险类型包含本国领土内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地形形变、海岸灾害、雪崩、森林火灾、气旋与风暴，以及4类技术灾害：核事故风险、工业事故风险、危险物料运输风险以及溃坝风险。
风险预防计划（Risk Prevention Plans，简称PPR）由1995年2月2日《加强环境保护法案》正式确立。该工具同时隶属于1987年7月22日《公民安全组织、森林防火与重大风险预防法案》的管辖范畴。风险预防计划的编制职责由国家承担，最终决策由省长作出。
无论属于自然灾害、技术灾害还是多灾害复合类型，风险预防计划均具备共通特征，其信息可划分为三大类别：
• 合规制图：将风险覆盖的地域范围进行地理界定，该边界明确了特定规制适用的区域。此类规制为地役权限制，并根据区域所面临的灾害等级设定差异化要求。上述区域以全覆盖研究区域的分区规划图进行可视化呈现。
• 灾害源文件：承载风险成因的灾害相关信息可嵌入编制报告，或作为风险预防计划的附件。此类文件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。
• 问题清单：风险预防计划编制过程中识别出的相关问题，同样可通过地图形式作为附件纳入获批文件。
鉴于各类PPR之间存在上述共通特征，且业界期望实现PPR数据的高水平标准化，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，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。
本文件的适用范围仅限于风险预防计划中的地理数据（无论是否属于合规范畴），且该标准无意对灾害相关知识进行标准化。
当前面临的核心挑战在于，需为风险预防计划的地理数据构建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相关部委的多个业务领域的关注。
