Dataset Direct Download Service (WFS): Vaucluse PPRN (84) — Summary Table of Documents

This sheet gives access to the localised data on the coverage of the department in prescribed and approved natural risk prevention plans.

The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are prepared by the State under the authority of the Prefect of Department. The PPRNs delineate areas exposed to major natural risk, regulate urbanisation according to the current occupation of the territory and the level of danger, and include measures to reduce vulnerability and safeguard existing issues.

These plans may be under development (prescribed), implemented in advance or approved. They can also be cancelled. Once approved, they are public easements and must be annexed to the local urban plans of the municipalities concerned.

In the summary table of documents, each PPRN is identified by a polygon that corresponds to all the municipalities affected by the PPRN whether it is prescribed, approved or cancelled. This geographical table makes it possible to give an overview of the situation in the department, of the municipalities concerned by a PPRN.

Two points of attention are brought to the attention of the user of this table:
— this table does not map the envelopes impacted by the risks.
— in the same municipality of the department, there may exist simultaneously an approved PPRN, and a prescribed PPRN (e.g.). In order to correctly visualise such cases, a thematic analysis of the table in the “ETAT” field can usefully be carried out, taking into account the following indications:
* “01” = “PRESCRIBED”
* “02” = “APPROVED”
* “03” = “CANCELLED”
* “04” = “APPLIED IN ADVANCE”

Each PPRN document in the N_DOCUMENT_PPRN geographical table is linked with its GASPAR code in the format “ddd[PREF|DDT|DDTM|DREAL]aaaannnn” (AAAA and NNNN correspond to the reference year and the order number of the associated PPR procedure in GASPAR):
1. its administrative procedure for drawing up (or revising) managed in the GASPAR application, on the one hand,
2. its set of numeric spatial data as described in the metadata sheet N_PPRN_AAAANNNN (#0001495).

本工作表可用于获取本省范围内已下达编制指令、已获批的自然风险预防规划（Natural Risk Prevention Plans，PPR）覆盖范围的本地化数据。

自然风险预防规划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《加强环境保护法》确立，由国家在省省长的职权框架下牵头编制。自然风险预防规划（Natural Risk Prevention Plans，PPRN）划定了受重大自然风险威胁的区域，结合当前国土利用现状与危险等级规范城市化建设活动，并配套制定降低风险暴露脆弱性、保障既有受保护对象的相关措施。

此类规划可处于已指令编制阶段、提前实施或已获批状态，亦可能已被撤销。规划获批后即成为公共地役权文件，必须附加至相关市镇的地方城市规划中。

在文档汇总表中，每份PPRN均通过多边形标识，该多边形覆盖所有受该PPRN影响的市镇，无论该PPRN处于已指令编制、已获批还是已撤销状态。此地理数据表可直观呈现本省的整体风险防控规划状况，以及受PPRN覆盖的相关市镇范围。

本数据表的使用者需注意以下两点：
— 本数据表未标注受风险影响的区域边界；
— 在本省的同一市镇内，可能同时存在已获批的PPRN与已指令编制的PPRN（例如）。为正确可视化此类场景，可对数据表中“ETAT”字段开展专题分析，参考如下标识：
* “01” = “已指令编制”
* “02” = “已获批”
* “03” = “已撤销”
* “04” = “提前实施”

地理数据表N_DOCUMENT_PPRN中的每份PPRN文档，均通过格式为“ddd[PREF|DDT|DDTM|DREAL]aaaannnn”的GASPAR代码（GASPAR）进行关联，其中AAAA与NNNN分别对应GASPAR系统中相关PPR编制（或修订）流程的参考年份与序号：
1. 其在GASPAR系统中管理的编制（或修订）行政流程；
2. 其对应的空间数值数据集集合，详见元数据表N_PPRN_AAAANNNN（编号#0001495）。
