Local planning plan for the municipality of Longueau

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数据标准适用于本地规划文件（Local Planning Documents，LDPs）以及属于PLU范畴的土地使用规划（Land Use Plans，POS）。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为可被地理信息系统（Geographic Information System，GIS）工具调用且具备互操作性的空间数据库，其覆盖范围涵盖图示分区规划、叠加管控要求以及适用于各类型区域的相关规制。

本COVADIS数据标准的制定，以法国国家地理信息委员会（Commission nationale de l'information géographique，CNIG）2012年更新的《城市规划文件数字化规范》为基础；而该规范本身又以2012年3月16日版整合修订后的《城市规划法典》为依据。尽管两份文件的制定初衷存在差异，但其提出的相关建议保持一致。

COVADIS数据标准旨在为现有PLU/POS空间数据在数字化基础设施中的组织与存储提供定义与架构，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，针对数据文件存储提供了额外建议（详见C部分）。此类存储方案仅适用于MAA与MEDDE数据基础设施的特定场景，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。
