DDT 48 — FLOOD RISK PREVENTION PLAN OF THE PRUNET HALL COMMUNE

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 process the different types of risk prevention plan (natural risk prevention plans PPRN, 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）中地理数据数字化存储所需的全部技术与组织规范。其所涉及的主要风险包含本国领土内可预见的八大类自然灾害：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，以及四类技术风险：核风险、工业风险、危险物料运输风险与堤坝溃决风险。

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。PPR工具隶属于1987年7月22日《民用安全组织、森林防火与重大风险防治法》。风险预防计划的编制职责由国家承担，最终审批决定由省长作出。

无论是自然灾害、技术灾害还是多灾害类型的风险预防计划，均具备共通特征。此类计划包含三类信息：
• 监管制图：将风险覆盖的领土范围以地理划定形式体现。该划定范围界定了适用特定监管要求的区域，此类监管要求以地役权为约束，并依据区域所承受的灾害等级设定差异化义务。上述区域以覆盖整个研究区域的分区规划图进行呈现。
• 风险源灾害：引发风险的灾害类型记载于灾害文件中，此类文件可纳入呈报报告或作为风险预防计划的附件。上述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地图。
• 风险预防计划编制过程中识别出的问题，也可通过地图形式作为附件附于获批文件之后。

不同类型PPR之间的上述共通性，以及实现PPR数据标准化的良好愿景，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限于风险预防计划中的地理数据，无论其是否具备监管属性。同时，PPR标准也并非旨在统一灾害相关知识的表述。

当前面临的核心挑战在于，为风险预防计划的地理数据提供统一的存储描述，鉴于此类数据受到农业、生态及可持续发展相关部委内多个专业领域的关注。
