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数据标准适用于地方规划文件（Local Planning Documents，简称LDPs）以及属于土地利用规划（PLU）范畴的土地利用规划方案（POSs）。本数据标准提供了一套技术框架，详细阐述了如何将上述规划文件数字化转换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。本标准同时涵盖图形化分区规划、叠加性要求以及适用于各类区域的管制规则。本COVADIS数据标准依据法国国家地理信息委员会（Commission nationale de l'information géographique，简称CNIG）2012年更新的《城市规划文件数字化规范》制定，而该规范本身又以2012年3月16日发布的整合版《城市规划法典》为依据。尽管两份文件的制定目的存在差异，但其提出的建议内容保持一致。COVADIS数据标准为以数字化基础设施形式组织、存储现有PLU/POS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流程。本COVADIS标准中的"数据结构"章节为数据文件存储提供了额外建议（详见C部分）。此类存储方案仅针对MAA与MEDDE数据基础设施制定，超出该应用场景则不具备适用性。市镇地图则属于另一项COVADIS数据标准的涵盖范畴。
