Dataset Direct Download Service (WFS): Risk — PPRT document on the Loir-et-Cher department

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 submission 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 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 mapping existing PPRTs on the department. Each PPRT document existing in the N_DOCUMENT_PPRT 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 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_PPRT_AAAANNNN (#0001496).风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日《加强环境保护法案》确立，是国家在风险预防领域的核心治理工具，其目标是对存在重大风险的区域的开发活动实施监测。PPR由省长批准，通常由省领土事务主管局（departmental directorates of the territories，DDT）负责实施。此类计划通过对现有或未来建筑设置建筑禁令或提出合规要求（含建设条款、减灾工程、农业使用限制或作业规范等），规制土地利用与开发活动，可分为拟定（法定备案）、提前实施及已获批三种状态。RPP文档包含报审说明、合规分区规划及监管规则，其他有助于理解该方案的图文资料（如风险隐患、相关问题等）可作为附件附加。每份PPR均由多边形矢量边界标识：若处于法定备案状态，该边界对应预案范围内受影响的市镇集合；若处于已获批状态，则对应受限区域的范围包络线。本地理数据表可用于在省内绘制现有PPRT文档的空间分布。存放在N_DOCUMENT_PPRT地理数据表中的每份PPRT文档，均与格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"的GASPAR代码相关联（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）：其一为在GASPAR系统中管理的PPR拟定（或修订）行政流程，其二为元数据表N_PPRT_AAAANNNN（编号#0001496）中描述的数值空间数据集。
