The Risk Prevention Plans (RPPs) were established by the Law of 2 February 1995 on the strengthening of environmental protection. They are the essential tool of the State in the field of risk prevention. Their objective is to control development in areas at major risk. PPRs are approved by the prefects and generally carried out by the Departmental Directorates of Territories (DDT). These plans regulate land use or land use through construction bans 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), applied in advance or approved. The PPR file contains a submission note, a regulatory zoning plan and a regulation. Other graphical documents that are useful for understanding the approach (alases, challenges, etc.) can be attached. Each PPR is spotted by a polygon that corresponds to the set of municipalities concerned with the scope of prescription when it is in the prescribed state; and the envelope of restricted zones 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 geographic table N_DOCUMENT_PPRT is linked using 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 PPR procedure in GASPAR): 1. its administrative procedure for preparing (or revising) managed in the GASPAR application, on the one hand, 2. to its series of numerical constituent geographical data described by the metadata sheet N_PPRT_AAAANNNN (#0001496) on the other hand.风险预防计划（Risk Prevention Plans, RPPs）由1995年2月2日颁布的《环境保护强化法》确立，是国家在风险预防领域的核心工具，其目标为管控高风险区域的开发活动。 RPPs由省长审批，通常由领土事务总局（Departmental Directorates of Territories, DDT）牵头实施。此类计划通过对现有或未来建筑设定建设禁令或提出相关要求，实现土地利用管控——包括建设规范、风险易损性降低工程、农业使用或作业限制等。 此类计划可处于编制报批、预实施或已获批三种状态。 RPP文件包含报审说明、管控分区规划与管控规程。此外，可附加有助于理解该计划的其他可视化文档（如相关别名、实施难点等）。每份RPP均通过多边形进行标注：若处于编制报批状态，则多边形对应纳入报批范围的全部市镇辖区；若处于已获批状态，则多边形对应受限区域的边界范围。 本地理表格可实现省内已存PPRTs的制图展示。地理表格N_DOCUMENT_PPRT中收录的每份PPRT文档，均可通过其GASPAR编码进行关联，该编码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中关联RPP流程的参考年份与序列号）： 1. 一方面关联至其在GASPAR系统中管理的编制（或修订）行政流程； 2. 另一方面关联至由元数据表N_PPRT_AAAANNNN（编号#0001496）所描述的一系列构成该计划的数值型地理数据。
