Dataset Direct Download Service (WFS): Plan for the prevention of natural risks of field movement — Municipality of Sauveterre — Document — Department of Tarn-et-Garonne

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 allows to map existing PPRNs on the department.
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).

风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日颁布的《加强环境保护法案》确立，是该国风险预防领域的核心政策工具，其目标是对存在重大风险区域的开发活动实施监测。
PPR由省长审批，通常由省级领土事务总局（Territorial Departmental Directorates，DDT）牵头实施。此类计划通过对现有及未来建筑设置建设禁令或提出相关要求（如建设条款、减灾工程、农业使用或作业限制等），规范土地使用与建设活动。
此类计划可分为制定中（已下达编制指令）、提前实施以及获批三种状态。
PPR文件包包含编制说明、管控分区规划与监管规则。此外，可附加有助于理解该计划实施思路的其他图文文档（如风险隐患、相关问题等材料）。每份PPR通过多边形进行标识：当计划处于制定中状态时，该多边形对应编制指令覆盖的全部市镇范围；当处于获批状态时，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PPRN的空间制图。
N_DOCUMENT_PPRN地理数据表中的每份PPRN文档，均与其GASPAR代码（GASPAR）相关联，该代码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中关联PPR流程的参考年份与序号）：
1. 一方面为在GASPAR系统中运行的PPR编制（或修订）行政流程，
2. 另一方面为元数据表N_PPRN_AAAANNNN（编号#0001495）中所描述的数值空间数据集集合。
