Municipal map of Fresnoy le Château

This COVADIS data standard concerns communal map documents (CCs). 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 standard of COVADIS data 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 COVADIS 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. Part C ‘Data Structure’ presented in this COVADIS 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COVADIS数据标准针对市政地图文档（CCs）。本标准提供了一套技术框架，详细阐述了如何在可被地理信息系统（GIS）工具使用且具备互操作性的空间数据库中，对这类城镇规划文档进行电子化转换。本标准涵盖片区图形规划图及其叠加的附属信息。COVADIS数据标准以CNIG于2012年制定的规划文档电子化规范为基础开发，而该规范本身又以2012年3月16日发布的整合版《城市规划法典》为依据。尽管二者的应用目标存在差异，但这两份文件所提出的建议保持一致。COVADIS数据标准为市政地图空间数据在基础设施中的组织与存储提供了相关定义及结构框架，而CNIG规范则用于界定这类数据的数字化流程。本COVADIS标准中提及的C部分“数据结构”，针对数据文件的存储提供了额外的建议。这些设定均针对负责农业与可持续发展的部委的公共数据基础设施定制，仅在其适用范围内有效。
