Municipal map of Saint Loup de Buffigny

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（COVADIS）数据标准面向市镇地图文档（CCs）。该数据标准提供一套技术框架，详细阐明了如何在可被地理信息系统（GIS）工具调用且具备互操作性的空间数据库中，完成此类城镇规划文档的数字化转换。本标准既涵盖分区图形平面图，也包含叠加于其上的各类关联信息。本COVADIS数据标准基于法国国家地理与森林信息中心（CNIG）2012年制定的规划文档数字化规范开发而成，而该CNIG规范本身则以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，但两份文件所提出的建议保持一致。COVADIS数据标准为在基础设施中组织与存储市镇地图的空间数据提供了明确定义与架构体系，而CNIG规范则用于规范此类数据的数字化实施流程。本COVADIS标准中的"C部分：数据结构"章节为数据文件的存储提供了补充建议，此类建议仅适用于农业与可持续发展部所属的公共数据基础设施场景，超出该范围则不具备适用性。
