Data batch direct download service (WFS): Estissac urban 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，LDP）以及PLU类土地使用规划（POS）。本数据标准构建了一套技术框架，详细阐述了如何将上述规划文档数字化转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。

COVADIS数据标准的制定依据为法国国家地理与森林信息委员会（CNIG）2012年更新的规划文档数字化规范，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的图示文档进行数字化转化后，将生成一套由多类对象目录组成的空间数据集：ZONE_URBA类涵盖PLU区划规划对应的城市片区（对应条款R.123-5至R.123-8），包括建成城区（U）、待城市化片区（AU）、农业片区（A）以及自然与森林片区（N）。每个片区均附带一项管制规则，该规则可根据建设用途的不同设定差异化条款，建设用途涵盖住宅、酒店住宿、办公、商业、手工业、工业、农业或林业作业以及仓储功能。

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）。此类要素叠加于规划文档的片区之上，通常会对该片区的开发建设施加额外约束，且每项管控要求均需附带一项管制规则。
