Data batch direct download service (WFS): Natural hazard prevention plan (PPRN) of the commune of CANTE

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.

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的全部技术与组织规范。
该国领土内可预见的重大风险包含八大类自然灾害与四大类技术灾害：自然灾害分别为洪水、地震、火山喷发、地形变动、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《加强环境保护法案》确立。该工具同时隶属于1987年7月22日《民用安全组织、森林防火与重大风险预防法案》的规制范畴。风险预防计划的编制工作由国家负责，最终审批决策由省长作出。
无论针对自然风险、技术风险还是多灾种风险，各类风险预防计划均具备共通性，其内容均包含三大类信息：
• 规制制图：指对受风险波及的领土范围开展地理界分。该界分明确了需适用特定规制的区域，此类规制属于地役权范畴，并依据区域所承受的灾害等级设定差异化约束要求。上述区域会在全覆盖研究区域的分区规划图中予以标注。
• 风险源灾害信息：即构成风险成因的灾害相关内容，可嵌入汇报报告或作为附件附加至风险预防计划（RPP）中。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图。
• 编制阶段识别出的问题：同样可通过地图形式作为附件，附加至已获批的风险预防计划文件中。
鉴于各类风险预防计划（PPR）之间的共通性，以及对PPR数据实现高水平标准化的需求，COVADIS最终选择采用单一数据标准。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，PPRN）与技术风险预防计划（Technological Risk Prevention Plans，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局限于风险预防计划（RPPs）中的地理数据，无论其是否属于规制类数据。同时，本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，需构建一套统一的描述规范以实现RPPs地理数据的同质化存储——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专业岗位的关注。
