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 data standard）适用于地方规划文件（LDPs）以及属于PLU范畴的土地使用规划方案（POSs）。该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数字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。本数据标准涵盖图形分区规划图、叠加适用的各类管控要求，以及适用于各类型地块的法规条例。COVADIS数据标准的制定依据为法国国家地理信息中心（CNIG）于2012年更新的城市规划文件数字化规范，而该CNIG规范本身又以2012年3月16日发布的整合修订版《城市规划法典》为基础。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内容保持一致。COVADIS数据标准为以数字基础设施形式组织与存储现有PLU/POS空间数据提供了统一定义与架构体系，而CNIG规范的作用则是规范此类数据的数字化工作。本COVADIS标准中的"Data Structure"章节针对数据文件的存储提出了额外建议（详见C部分），此类建议是专为MAA与MEDDE数据基础设施制定的专属方案，仅在其对应场景中适用。另有一项独立的COVADIS数据标准专门针对市镇地图进行规范。
