Map visualisation service (WMS) of the dataset: Documents of the PPRT Titanobel

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《加强环境保护法》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。 此类计划由省长核准，通常由领土事务省级总局（Departmental Directorates of Territories, DDT）牵头实施。此类计划通过针对现有或未来建筑的建设禁令或要求（包括建设条款、降低风险脆弱性的工程措施、农业使用或作业限制等），对土地用途与开发活动进行规制。 此类计划可能处于编制中（法定待核准状态）、提前实施或已核准状态。 风险预防计划文件包含提交说明、监管分区规划及监管条例。其他有助于理解编制思路的图形文档（如附件、编制难点说明等）可作为附件一并提交。每份风险预防计划均由多边形标识：当计划处于法定待核准状态时，该多边形对应纳入法定编制范围的全部市镇；当计划处于已核准状态时，则对应受限区域的范围边界。 本地理数据表可用于绘制省内现存技术风险预防计划（Technological Risk Prevention Plans, PPRTs）的分布图。 地理数据表N_DOCUMENT_PPRT中每份现存的技术风险预防计划文档，均通过其GASPAR代码进行关联，代码格式为"ddd[PREF|DDT|DDTM|DREAL]aaaannnn"（其中AAAA与NNNN分别对应GASPAR系统中相关风险预防计划程序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（制定或修订）行政程序； 2. 另一方面关联至由元数据表单N_PPRT_AAAANNNN（#0001496）描述的系列数值型组成地理数据。
