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，简称LDPs）以及作为土地利用规划（Land Use Plan，简称PLU）的POSs。本数据标准提供了一套技术框架，详细说明了如何将此类城镇规划文件电子化，并存储于可供地理信息系统（Geographic Information System，简称GIS）工具使用且具备互操作性的空间数据库中。本标准既涵盖各片区的图形规划图纸，也包含附着于这些图纸之上的关联信息。本CNIG数据标准是以CNIG于2012年制定的规划文件电子化规范为基础开发的，而该规范本身又依托2012年3月16日发布的整合版《城市规划法典》。尽管二者的应用目标不尽相同，但两份文件所提出的建议保持一致。CNIG数据标准用于为市政地图的空间数据在基础设施中的组织与存储提供定义及架构，而CNIG规范则用于界定此类数据的数字化工作边界。本CNIG标准中的"数据结构"章节还针对数据文件的存储提出了补充建议。此类存储选择仅适用于负责农业与可持续发展事务的部委的公共数据基础设施，超出该场景范围则不具备适用性。
