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，缩写LDP）以及属于PLU范畴的土地利用规划（Land Use Plans，缩写POS）。本标准提供一套技术框架，详细阐明如何将上述规划文件电子化转换为可被地理信息系统（Geographic Information System，缩写GIS）工具调用且具备跨系统互操作性的空间数据库。本数据标准覆盖图形分区规划、叠加约束条件以及适用于各类地块的管控规则。COVADIS数据标准由法国国家地理与林业信息中心（Centre National de l'Information Géographique et Forestière，缩写CNIG）2012年更新的《城市规划文件电子化规范》制定而来，该规范本身则基于2012年3月16日发布的整合版《城市规划法典》。尽管两份文件的制定目标存在差异，但其所提出的建议保持一致。COVADIS数据标准为现有PLU/POS空间数据在数字基础设施中的组织与存储提供了统一定义与结构框架，而CNIG规范则用于界定此类数据的数字化实施流程。本COVADIS标准中的"数据结构"章节针对数据文件存储提出了额外建议（详见Part C）。此类规范仅适用于MAA与MEDDE的数据基础设施场景，超出该范围则不具备适用性。市镇地图属于另一项COVADIS数据标准的覆盖范畴。
