Dataset Direct Download Service (WFS): Plan for the prevention of natural risks of landslide — Commune d’Auvillar — 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日发布的《加强环境保护法案》确立，是国家在风险预防领域的核心政策工具，其目标是对存在重大风险的区域内的开发活动实施动态监测。 PPR由省长批准，通常由领地部门主管局（departmental directorates of the territories，DDT）牵头实施。此类计划通过对现有及未来建筑设定建造禁令或要求（含建造规范、灾害脆弱性降低工程、农业使用限制或作业规范等），实现对土地用途与开发行为的管控。 此类计划可分为三种状态：处于编制阶段（已下达编制指令）、预实施状态以及已获批状态。 PPR文件包含说明性文稿、监管分区规划与监管条例。其他有助于理解该规划编制思路的图文资料（如灾害风险分布图、核心关切问题梳理图等）可作为附件附入。每份PPR通过一个面要素（polygon）进行标识：当计划处于编制阶段时，该面要素对应编制指令覆盖范围内的全部市镇；当计划获批时，则对应受限区域的包络范围。 本地理数据表可用于绘制各省内已生效的PPRN分布图。 N_DOCUMENT_PPRN地理数据表中的每份PPRN文档均与其GASPAR代码相关联，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），具体包含两部分内容： 1. 在GASPAR系统中管理的PPR编制（或修订）行政流程； 2. 元数据表N_PPRN_AAAANNNN（编号#0001495）中描述的全套数字空间数据。
