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.

COVADIS数据标准（COVADIS Data Standard）涵盖风险预防计划（Risk Prevention Plans，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。该国境内可预见的主要风险包含8类主要自然灾害与4类技术风险：其中自然灾害分别为洪水、地震、火山喷发、地形异动、海岸灾害、雪崩、森林火灾、飓风与风暴；技术风险则涵盖核风险、工业风险、危险货物运输风险以及溃坝风险。

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，而PPR工具则隶属于1987年7月22日《民用安全组织、森林防火与重大风险防控法案》。风险预防计划（RPP）的编制工作由国家负责，最终由省长审批确定。

无论针对自然灾害、技术风险还是多灾种的风险预防计划，其内容均存在共性，均包含三类信息：
• 监管制图环节会将风险所涉领土的地理边界进行具象化呈现。该边界划定了适用特定监管要求的区域，此类监管要求属于地役权范畴，并会依据区域面临的风险等级制定差异化约束标准。上述区域会在全覆盖研究区域的分区规划图中予以标注。
• 风险的致灾因子信息收录于灾害文档中，此类文档可嵌入汇报材料或作为附件附于风险预防计划（RPP）之后，用于标注风险预防计划中所考量的各类灾害的不同强度等级。
• 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附于获批文件之后。

鉴于不同类型PPR之间存在上述共性，且为实现PPR数据的高水平标准化，COVADIS最终选用了一套统一的数据标准，该标准具备足够的通用性，可适配各类风险预防计划的处理需求，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，其适用范围仅涵盖风险预防计划（RPPs）中的地理数据（无论是否属于监管范畴）。此外，PPR标准亦并非旨在实现灾害认知的标准化。该标准的核心目标是为RPPs的地理数据提供统一的存储描述规范，鉴于此类数据分别受到农业、生态与可持续发展相关部委内部多个专业领域的关注。
