Dataset Direct Download Service (WFS): List of digital technology risk prevention plans in the Charente-Mairitime department

The Risk Prevention Plans (PPR) were established by the Act of 2 February 1995 on strengthening the protection of the environment. They are the key instrument of the State in the field of risk prevention. Their objective is to monitor development in areas exposed to a major risk.
The PPRs are approved by the prefects and generally carried out by the departmental directorates of the territories (DDT). These plans regulate land use or land use through building prohibitions or requirements on existing or future buildings (constructive provisions, vulnerability reduction work, restrictions on agricultural use or practices, etc.).
These plans may be under development (prescribed), implemented in advance or approved.
The RPP file contains a presentation note, a regulatory zoning plan and a regulation. Other graphic documents that are useful for understanding the approach (e.g. hazards, issues, etc.) can be attached. Each PPR is identified by a polygon that corresponds to the set of municipalities
the scope of the prescription when it is in the prescribed state; and the envelope of restricted areas when it is in the approved state.
This geographical table makes it possible to map existing PPRTs on the department.
Each PPRT document existing in the geographical table N_DOCUMENT_PPRT 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_PPRT_AAAANNNN (#0001496).

风险预防计划（PPR）由1995年2月2日《加强环境保护法》确立，为国家在风险预防领域的核心治理工具，其宗旨为对存在重大风险区域的开发活动进行监测管控。
PPR由省长审批通过，一般由领地部门局（DDT）牵头执行。此类计划通过对现有及未来建筑实施建设禁令或提出建设要求（如建设管控条款、脆弱性降低工程、农业使用或作业限制等），对土地利用进行规范与调整。
此类计划可分为三类状态：法定编制阶段、先期实施阶段及已获批阶段。
PPR档案包含介绍性说明文档、合规分区规划及管控规章。可附加其他有助于理解该规划方案的图文资料（如风险点位、相关问题等）。每份PPR均通过多边形矢量进行标识：当计划处于法定编制阶段时，该多边形对应划定的适用市镇范围；当计划获批后，则对应受限区域的边界包络线。
本地理数据表可实现省内现有PPRT（PPRT）的空间制图展示。地理数据表N_DOCUMENT_PPRT中现存的每份PPRT文档，均与其GASPAR编码绑定，编码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应关联PPR流程的参考年份与序号）：
1. 其一为在GASPAR系统中管理的编制（或修订）行政流程；
2. 其二为元数据表N_PPRT_AAAANNNN（编号#0001496）中描述的数值空间数据集。
