This COVADIS 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 planning documents into a spatial database that can be used by a GIS tool and interoperable. This standard of data concerns both the graphic zoning plans, the superimposed requirements and the regulations applying to each type of area.This standard of COVADIS data was developed on the basis of the specifications for the dematerialisation of urban planning documents updated 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 existing PLU/POS spatial data in an infrastructure in digital form, while the CNIG specification serves to frame the digitisation of such data. The ‘Data Structure’ section presented in this COVADIS standard provides additional recommendations for the storage of data files (see Part C). These are choices specific to the MAA and MEDDE data infrastructure that do not apply outside their context. Communal maps are the subject of another COVADIS data standard.本COVADIS数据标准（COVADIS）适用于地方规划文件（Local Planning Documents，简称LDPs）以及作为PLU的土地利用规划（POS）。本数据标准提供了一套技术框架，详细阐述了如何将此类规划文件电子化，转化为可被地理信息系统（Geographic Information System，简称GIS）工具使用且具备互操作性的空间数据库。该数据标准涵盖图形区划图、叠加式管控要求以及适用于各类地块的相关规制。COVADIS数据标准由法国国家地理与地籍信息中心（CNIG）2012年更新的城市规划文件电子化规范制定而来，该规范本身又基于2012年3月16日发布的《城市规划法典》整合版本。尽管两份文件的定位有所差异，但其提出的各项建议保持一致。COVADIS数据标准为以数字化基础设施组织、存储现有PLU/POS空间数据提供了明确定义与标准架构，而CNIG规范则用于界定此类数据的数字化工作范畴。本COVADIS标准中的“数据结构”章节还针对数据文件的存储提出了额外建议（详见C部分）。此类建议仅适用于MAA与MEDDE的数据基础设施，超出该场景则不具备适用性。市镇地图则属于另一项COVADIS数据标准的覆盖范畴。
