Simple download service (Atom) of the dataset: Natural hazard prevention plan — List of types of risks treated — Department of Tarn-et-Garonne

Non-geometric table to be used for multi-hazard RPPs to inform the types of risk addressed in the RPP.

Plans for the prevention of natural hazards (PPRN) 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 PPRNs 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 PPRN 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 PPRN is identified by a polygon that corresponds to the set of affected municipalities within 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 this 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 serial number of the associated PPRN 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 constituent geographic data described in the metadata sheet N_PPRN_AAAANNNN, on the other hand.

多灾害风险防治计划（RPP，Risk Prevention Plan）专用的非几何数据表，用于明确该类计划所覆盖的风险类型。
1995年2月2日《加强环境保护法案》确立了自然灾害风险防治计划（PPRN，Plans for the Prevention of Natural Hazards），该计划是国家在风险防治领域的核心工具，旨在对重大风险暴露区域的开发活动进行监测。
此类计划由省长审批，通常由领土事务省局（DDT，Departmental Directorates of Territories）牵头落实。该类计划通过对既有或拟建建筑施加建筑禁令或相关要求（包括建设规范、易损性降低工程、农业用途或耕作方式限制等），对土地利用进行规制。
此类计划可处于编制待批、提前实施或已获批三种状态。
PPRN档案包含编制说明、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可视化文档（如灾害分布、核心问题等相关素材）。当PPRN处于编制待批状态时，以对应其覆盖范围内受影响市镇的多边形矢量范围作为标识；当处于获批状态时，则以其管制区域的包络范围作为标识。本地理数据表可用于绘制省内现有PPRN的空间分布图。
本地理数据表中的每份PPRN文档，均关联有格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"的GASPAR编码（其中AAAA与NNNN分别对应GASPAR系统中关联PPRN流程的参考年份与序列号）：
1. 一方面关联其在GASPAR系统中管理的编制（或修订）行政流程，
2. 另一方面关联元数据表N_PPRN_AAAANNNN中描述的全套组成地理数据。
