DDT 48 — MENDE RAIN

This CNIG data standard concerns local planning documents (LDPs) and land use plans (POSs that are PLU). This data standard provides a technical framework describing in detail how to dematerialise these town planning documents in a spatial database that can be used by a GIS tool and interoperable. This standard of data covers both the graphical plans of sectors and the information overlaying them. This CNIG data standard was developed on the basis of the specifications for the dematerialisation of planning documents created in 2012 by the CNIG, itself based on the consolidated version of the urban planning code dated 16 March 2012. The recommendations of these two documents are consistent even if their purpose is not the same. The CNIG data standard provides definitions and a structure for organising and storing spatial data from communal maps in an infrastructure, while the CNIG specifications are used to frame the digitisation of these data. The ‘Data Structure’ section presented in this CNIG standard provides additional recommendations for the storage of data files. These are specific choices for the common data infrastructure of the ministries responsible for agriculture and sustainable development, which do not apply outside their context.本CNIG数据标准适用于地方规划文件（LDPs）以及属于土地利用规划（PLU）范畴的POSs类规划方案。本标准构建了一套技术框架，详细阐述了如何将此类城镇规划文件电子化，并存储于可被地理信息系统（Geographic Information System，简称GIS）工具调用且具备互操作性的空间数据库中。本标准既涵盖片区图形规划图则，也包含附着于图则之上的各类关联信息。本CNIG数据标准由CNIG于2012年制定的规划文件电子化规范衍生而来，而该规范本身则依托2012年3月16日发布的《城市规划法典》整合版本编制。尽管两份文件的制定目的有所不同，但其提出的技术建议却保持一致。CNIG数据标准旨在为市政地图的空间数据组织与存储提供明确定义与架构规范，而CNIG相关规范则用于界定此类数据的数字化实施框架。上述规范均为负责农业与可持续发展的各部委共同数据基础设施所设定的专属方案，仅在其适用范围内有效。
