Local planning plan for the municipality of Flesselles

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（COVADIS data standard）适用于地方规划文件（Local Planning Documents, LDPs）以及属于地方城市规划计划（PLU）范畴的土地使用规划（Land Use Plans, POSs）。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件数字化转换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。本标准涵盖图形分区规划图、叠加适用要求以及适用于各类区域的相关法规。 COVADIS数据标准的制定以法国国家地理与林业信息中心（Centre National de l'Information Géographique et Forestière, CNIG）于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日发布的整合版《城市规划法典》为依据。尽管二者的制定目标不尽相同，但相关建议内容保持一致。COVADIS数据标准为在数字基础设施中组织与存储现有PLU/POS空间数据提供了统一定义与架构规范，而CNIG的上述规范则用于明确此类数据的数字化工作框架。 本COVADIS标准中的“数据结构”章节还为数据文件的存储提供了额外建议（详见C部分）。此类建议属于MAA与MEDDE数据基础设施的专属适配方案，不适用于该范围之外的场景。市镇地图则属于另一项COVADIS数据标准的涵盖范畴。
