Data batch direct download service (WFS): Departmental Assembly of Natural Risk Prevention Plans (PPRN) on the Hautes-Pyrénées

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.
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.

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.

本数据集涵盖该国领土内可预见的八大主要自然灾害风险，分别为洪涝、地震、火山喷发、地形变动、海岸灾害、雪崩、森林火灾以及气旋与风暴。
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PPR工具隶属于1987年7月22日《公共安全组织、森林防火与重大风险预防法案》所规范的范畴。风险预防计划的编制工作由国家负责，并由省长签署生效。无论风险类型为自然风险、技术风险还是多灾种风险，风险预防计划均具备共通特征，其包含三类信息：
• 合规区划图：通过地理边界划定受风险影响的管辖区域，该边界明确了适用特定规制的范围。此类规制为限制性地役权，并根据区域面临的灾害等级设定差异化要求。上述区域将通过全覆盖研究区域的分区规划图进行可视化呈现。
• 风险源灾害信息：相关灾害内容收录于灾害文档中，可嵌入编制报告或作为PPR的附件。此类文档用于绘制风险预防计划所考量的各类灾害的不同强度等级分布图谱。
• 编制过程中识别出的相关问题，同样可通过地图形式附于获批后的正式文件中。
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PPR中的地理数据，无论其是否具备合规属性。此外，本PPR标准亦无意统一灾害认知范畴。
当前面临的核心挑战在于，为PPR的地理数据构建统一的存储描述规范——鉴于此类数据分别受到负责农业、生态与可持续发展的政府部门内多个专业领域的关注。
