Data batch direct download service (WFS): Natural Risk Prevention Plan (NRPP) of Gousse — Landes (40)

The COVADIS Risk Prevention Plan Data Standard contains all the technical and organisational specifications for the digital storage of the spatial 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 they are natural, technological or multi-risk, 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 (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风险预防计划数据标准（COVADIS Risk Prevention Plan Data Standard）涵盖了风险预防计划（Risk Prevention Plans，简称RPPs）中空间数据数字化存储所需的全部技术与组织规范。

该标准覆盖的主要风险包括本国领土范围内可预见的8类主要自然灾害：洪涝、地震、火山喷发、地面运动、海岸带灾害、雪崩、森林火灾、气旋与风暴，以及4类技术风险：核风险、工业风险、危险货物运输风险与堤坝溃坝风险。

风险预防计划（PPR，全称Risk Prevention Plans）由1995年2月2日发布的《加强环境保护法案》确立。该工具同时隶属于1987年7月22日颁布的《民用安全组织、森林防火与重大风险预防法》。风险预防计划的编制工作由国家负责，由省长（Prefect）审批决定。无论是自然风险、技术风险还是多风险类型的风险预防计划，均存在共通之处。

此类计划包含三类核心信息：
— 规制性地图：对受风险影响的领土进行地理划定，明确特定规制条款适用的区域。此类规制为限制性土地使用管制，并根据区域所面临的灾害等级设定差异化要求。上述区域会在覆盖整个研究区域的分区规划图中予以标注。
— 风险源灾害信息：收录于灾害文档中，可嵌入汇报说明或作为风险预防计划的附件。此类文档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相关问题，也可通过地图形式作为附件并入已获批的正式文件中。

不同类型风险预防计划之间的共通性，以及提升风险预防计划数据标准化水平的需求，促使COVADIS采用统一的数据标准，该标准具备足够的通用性，可适配各类风险预防计划，包括自然风险预防计划（Natural Risk Prevention Plans，简称PPRN）与技术风险预防计划（Technological Risk Prevention Plans，简称PPRT）。

本数据标准并非对风险预防计划档案的完整建模，其适用范围仅局限于风险预防计划中的地理数据，无论此类数据是否具备规制属性。同时，本标准亦无意对灾害认知进行标准化。

鉴于风险预防计划中的地理数据受到农业、生态与可持续发展等多个政府部门相关从业者的关注，本标准的核心目标是实现风险预防计划地理数据的统一存储描述。
