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》确立，是国家在风险预防领域的核心治理工具，其目标为对存在重大风险的区域的开发活动开展监测。
风险预防计划由省长批准，通常由省领土事务总局（Departmental Directorates of the Territories，DDT）负责推进实施。此类计划通过对现有或未来建筑实施建筑禁令或提出相关要求（包括建设条款、降低脆弱性工程、农业使用或耕作限制等），对土地使用进行管控。
此类计划可分为编制中（法定规定状态）、提前实施及已获批三类。
PPR文件包含说明性纪要、合规分区规划及监管规则，此外可附加有助于理解该方案的其他可视化文档（如风险隐患、相关问题等材料）。每份风险预防计划均由多边形矢量边界标识：当计划处于法定编制状态时，该边界对应计划管控范围内的所有市镇辖区；当计划处于获批状态时，该边界则对应受限区域的覆盖范围。
本地理数据表可实现省内现存PPRN的空间制图展示。N_DOCUMENT_PPRN地理数据表中的每份PPRN文档，均与其GASPAR编码相关联，该编码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应关联PPR流程的参考年份与GASPAR系统内的序号）：其一为在GASPAR系统中管理的PPRN编制（或修订）行政流程；其二为元数据表N_PPRN_AAAANNNN（编号#0001495）中所描述的数值空间数据集。
