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（Local Planning Documents，LDPs）以及作为土地利用规划（Land Use Plan，PLU）的土地使用计划（POSs）。本数据标准提供了一套技术框架，详细阐述了如何将此类城镇规划文档电子化并存储于可被地理信息系统（Geographic Information System，GIS）工具调用且具备互操作性的空间数据库中。本数据标准既涵盖分区图形规划图件，也包含图件所承载的附属信息。本CNIG数据标准以CNIG于2012年制定的规划文档电子化规范为依托，而该规范本身则基于2012年3月16日发布的整合版《城市规划法典》。尽管这两份文件的应用场景不尽相同，但其所提出的建议保持一致。CNIG数据标准旨在为基础设施中市镇地图空间数据的组织与存储提供定义与结构框架，而CNIG规划文档电子化规范则用于规范此类数据的数字化流程。本CNIG标准中“数据结构”章节为数据文件的存储提供了补充性建议。此类选择仅适用于负责农业与可持续发展事务的部委的共用数据基础设施，超出该场景则不具备适用性。
