Municipal map of Chalette sur Voire

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数据标准适用于社区地图文档（CCs）。该标准提供了一套技术框架，详细阐述如何将此类城镇规划文档进行数字化转换，并存储于可被地理信息系统（GIS）工具调用且具备互操作性的空间数据库中。本标准既涵盖各分区的图形规划图件，也包含图件所承载的附加信息。 本COVADIS数据标准基于法国国家地理信息委员会（CNIG）2012年制定的规划文档数字化规范开发，该规范又以2012年3月16日发布的整合版《城市规划法典》为编制依据。尽管两份文件的制定初衷有所差异，但其提出的技术建议保持一致。 COVADIS数据标准旨在为社区地图空间数据的组织与存储提供明确定义及规范架构，而CNIG制定的规范则用于界定此类数据数字化工作的边界。 本COVADIS标准中C部分“数据结构”针对数据文件的存储提出了补充性建议。 上述规范仅针对负责农业与可持续发展事务的部委的公共数据基础设施制定，超出该应用场景则不具备适用性。
