Pos (doc. of 11.02.2000) from the municipality of Léré

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）以及PLU类POS土地利用规划。本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档电子化转化为可被地理信息系统（Geographic Information System，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、叠加要求以及适用于各类区域的相关法规。 COVADIS数据标准由法国国家地理信息委员会（Commission nationale de l'information géographique，CNIG）于2012年更新的《城市规划文档电子化规范》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》。尽管二者的制定目的存在差异，但两份文件的建议内容保持一致。COVADIS数据标准为在数字基础设施中组织与存储现有PLU/POS空间数据提供了定义与架构，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”章节还针对数据文件存储提出了额外建议（详见C部分）。此类选型方案为MAA与MEDDE数据基础设施专属，仅在其适用范围内有效。市镇地图则属于另一项COVADIS数据标准的覆盖范畴。
