Dataset Direct Download Service (WFS): Plan for the prevention of natural risks of landslide — Commune de Montastruc — 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》制定，是国家开展风险预防工作的核心工具。其目标是对存在重大风险的区域的开发活动进行监测。 PPR由省长审批，通常由领土事务省局（DDT）负责落地实施。此类计划通过对现有或未来建筑制定禁止性或强制性要求（包括建设条款、降低脆弱性工程、农业用途或作业限制等），对土地利用或土地开发行为进行规制。 PPR可处于编制中（已下达编制指令）、提前实施或已获批三种状态。 PPR文件包含说明文档、管制区划图及管制条例，还可附加有助于理解该计划的其他图形资料（如危险源分布图、相关问题说明等）。每份PPR通过一个多边形进行标识：若处于编制状态，该多边形对应管控覆盖的所有市镇范围；若处于获批状态，则对应管制区域的包络范围。 本地理数据表可实现省域范围内现有PPRN的空间制图。 N_DOCUMENT_PPRN地理数据表中的每份PPRN文档，均通过格式为“ddd[PREF|DDT|DDTM|DREAL]aaaannnn”的GASPAR编码进行关联，其中“aaaa”与“nnnn”分别代表参考年份及关联PPR流程在GASPAR系统中的序号： 1. 其一为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_PPRN_AAAANNNN（#0001495）中描述的全套数值空间数据。
