Plu (doc. of 23.9.2011) from the municipality of Méry-sur-Cher

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，LDPs）与属于PLU范畴的土地利用规划（POS）。本数据标准提供一套技术框架，详细阐明如何将此类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。该标准覆盖图形分区规划图、叠加性要求以及适用于各类区域的规制条款。 本COVADIS数据标准的制定依据为CNIG于2012年更新的城市规划文件数字化规范；该规范本身又依托于2012年3月16日发布的《城市规划法典》整合版。尽管两份文件的制定目标存在差异，但其提出的相关建议彼此契合。 COVADIS数据标准提供了相关定义与组织结构，用于在数字化基础设施中组织、存储现有PLU/POS空间数据；而CNIG规范的作用则是为此类数据的数字化工作划定实施框架。 本COVADIS标准中的"数据结构"章节，为数据文件的存储提供了额外建议（详见C部分）。此类存储规范为MAA与MEDDE数据基础设施所特有，不适用于其应用场景之外的范围。 市镇地图属于另一项COVADIS数据标准的覆盖范畴。
