Map Viewing Service (WMS) of the dataset: Technological risk prevention plan for the Vosges 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 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 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 makes it possible to map the existing technological PPRs (PPRTs) on the department. Each PPRT document 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 the order number of the associated PPR procedure in GASPAR).风险预防计划（Risk Prevention Plans，PPR）由1995年2月2日《加强环境保护法》确立，是国家在风险预防领域的核心管控工具，其目标是对重大风险暴露区域的开发活动进行动态监测。 PPR由省长审批，通常由省领土事务局（DDT）牵头实施。此类计划通过针对现有及未来建筑的禁令与要求（涵盖建设条款、降低脆弱性工程、农业使用或作业限制等）规范土地使用。 此类计划可分为三类状态：编制中（规定状态）、预实施及已获批。 PPR数据包包含说明性简报、管制区划图及管制条例。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）可作为附件添加。每一项PPR均通过多边形进行标识：当计划处于规定状态时，该多边形对应规定范围内受影响的市镇集合；当计划处于获批状态时，则对应受限区域的边界范围。该地理数据表可用于在省内绘制现有技术型风险预防计划（PPRTs，以下简称PPRT）的空间分布图。"N_DOCUMENT_PPRT"地理数据表中的每份PPRT文档均与其GASPAR编码关联，该编码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应关联PPR流程的参考年份与序号）。
