Data batch direct download service (WFS): Natural Risk Prevention Plan (PPRN) of the municipality of BELESTA

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，涵盖了风险预防计划（Risk Prevention Plans，简称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。
该标准覆盖的重大风险包含该国领土内可预见的8类主要自然灾害与4类技术风险：自然灾害包括洪水、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；技术风险则涵盖核风险、工业风险、危险物料运输风险以及坝体溃决风险。
风险预防计划（PPR，全称Risk Prevention Plans）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，最终由省长签署发布。
无论是自然风险、技术风险还是多灾害风险，各类风险预防计划均具备共通特性，其包含的信息可分为三大类别：
• 规制性测绘：将风险覆盖的地域以地理边界形式划定，明确适用特定规制的区域范围。此类规制属于地役权类限制要求，并会根据区域所面临的灾害等级制定差异化的义务标准。上述区域将在覆盖研究全域的分区规划图中予以标注。
• 风险源灾害信息：即引发风险的各类灾害相关资料，此类资料可纳入编制报告正文，或作为附件附于RPPs之后。这些资料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。
• 编制过程中识别出的问题：此类内容也可通过地图形式作为附件，纳入已获批的风险预防计划文件中。
鉴于各类PPR之间存在上述共通特性，加之各方对PPR数据实现高水平标准化的诉求，COVADIS最终选择采用一套通用数据标准，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（PPRN）与技术风险预防计划（PPRT）。
本数据标准并非对风险预防计划卷宗的完整建模。
本文件的适用范围仅局限于RPPs中的地理数据，无论其是否属于规制性内容；同时，本PPR标准也并非旨在实现灾害相关知识的标准化。
鉴于农业、生态及可持续发展相关部委内的多个从业群体均对RPPs的地理数据存在使用需求，本标准的核心挑战在于实现RPPs地理数据的统一存储描述。
