Municipal map of Maraye en Othe

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数据标准面向社区地图文档（CCs）。本数据标准构建了一套技术框架，详细阐述如何将此类城镇规划文档数字化并存储于空间数据库中，使其可被地理信息系统（GIS）工具调用且具备互操作性。该标准涵盖两类核心内容：分区图形规划图则及其叠加的关联信息。COVADIS数据标准的制定基于CNIG于2012年出台的规划文档数字化规范，而CNIG的该项规范本身又以2012年3月16日发布的《城市规划法典》整合版为依据。尽管二者的应用目标不尽相同，但两份文件的建议内容保持一致。COVADIS数据标准为在数据基础设施中组织与存储社区地图的空间数据提供了明确定义与架构体系，而CNIG的规范则用于规范此类数据的数字化流程。本COVADIS标准的第三部分"数据结构"针对数据文件的存储给出了补充建议。此类建议是针对负责农业与可持续发展的各部公共数据基础设施的特定适配方案，仅适用于该场景，超出该范围则不具备适用性。
