Plan for the prevention of natural risks of field movement — Municipality of Lauzerte — Department of Tarn-et-Garonne

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，缩写RPP）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。
其涵盖的主要风险包括该国领土内可预见的八大类自然灾害：洪水、地震、火山喷发、地形位移、海岸灾害、雪崩、森林火灾、气旋与风暴，以及四大类技术风险：核风险、工业风险、危险材料运输风险以及大坝溃坝风险。
风险预防计划（Risk Prevention Plans，缩写PPR）由1995年2月2日《关于加强环境保护的法案》确立。该工具同时隶属于1987年7月22日《关于组织公民安全、森林防火与重大风险预防的法律》的规制范畴。
风险预防计划的编制工作由国家负责，最终审批决定由省长作出。
无论针对自然风险、技术风险还是复合型灾害，各类风险预防计划均存在共通特性。它们均包含三类信息：
• 管控区划图：将风险覆盖的领土范围以地理边界形式划定，该边界界定了需适用特定管控规则的区域。此类规则属于地役性约束要求，并需根据区域所面临的灾害等级调整约束标准。上述区域将在覆盖研究全域的区划图中予以标注。
• 风险源灾害信息：即引发风险的灾害相关内容，收录于可嵌入汇报文档或作为RPP附件的灾害文件中。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。
• 编制识别问题：在风险预防计划编制过程中识别出的问题，同样可通过地图形式作为附件附于获批文件之后。
各类PPR之间的共通特性，以及实现PPR数据标准化的迫切需求，推动COVADIS选择了单一数据标准。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，缩写PPRN）与技术风险预防计划（Technological Risk Prevention Plans，缩写PPRT）。
本数据标准并非旨在完整建模风险预防计划卷宗，其适用范围仅局限于RPP中的地理数据，无论该数据是否属于管控类信息。
同时，PPR标准也并非用于统一灾害相关的专业认知。
本标准所要达成的核心目标，是为RPP中的地理数据提供统一的存储描述规范——鉴于此类数据对于农业、生态与可持续发展相关部委内的多个专业领域均具有重要应用价值。
