Chappes Town Planning Document

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 COVADIS data was developed on the basis of the specifications for the dematerialisation of planning documents updated in 2012 by the CNIG, itself based on the consolidated version of the urban planning code dated 16 March 2012.
The dematerialisation of the graphic documents of a PLU, POS generates a set of spatial data composed of several catalogues of objects:
Class ZONE_URBA containing the urban areas corresponding to the zoning plan of the PLU (R.123-5 to 8): urban areas (U), areas to be urbanised (AU), agricultural areas (A) and natural and forest areas (N). A regulation is attached to each area. The by-law may lay down different rules, depending on whether the purpose of the constructions will relate to housing, hotel accommodation, offices, trade, crafts, industry, agricultural or forestry operations or warehouse functions.
Class PRESCRIPTION containing all surface, linear and point requirements for PLU or POS (R123-11). They are superimposed on an area in the planning document and in general impose an additional constraint on the settlement of the area. A regulation shall be attached to each prescription.

本COVADIS数据标准适用于地方规划文件（Local Planning Documents，缩写LDP）以及属于土地利用规划（PLU）范畴的土地利用规划文件（POS）。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COVADIS数据标准的制定依据CNIG于2012年更新的规划文件数字化转换规范，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》为基础。

对PLU、POS的图示文件进行数字化转换后，将生成一组由多类对象目录构成的空间数据：
- ZONE_URBA类，包含与PLU分区规划对应的城市用地分区（对应条款R.123-5至R.123-8）：城市建设用地区（U）、待城市化地区（AU）、农业用地区（A）以及自然与林地区（N）。每个分区均附带一项管控规则，该规则可根据建设用途的不同设定差异化要求，建设用途涵盖住宅、酒店住宿、办公、商业、手工业、工业、农林作业或仓储功能等。
- PRESCRIPTION类，涵盖PLU或POS的所有面状、线状与点状管控要求（对应条款R.123-11）。此类要求叠加于规划文件的某一分区之上，通常会对该区域的建设开发施加额外约束。每项管控要求均需附带一项管控规则。
