Computerised Cadastral Plan (PCI) in vector format — Chiry-Ourscamp common — 2021

The cadastral plan is an administrative document that proposes the only large-scale parcel plan covering the national territory. The cadastral plan of a commune is divided into sections, which can be divided into subdivisions of sections, commonly referred to as “plan sheets”. The plot is the basic cadastral unit. It is a single-contained plot located in the same place and belonging to the same owner. The cadastral plan in vector format comes mainly from the digitisation of the cadastral plan paper or raster carried out in the framework of agreements with local and regional authorities. Cadastral plans in vector format in metropolitan France are currently georeferenced in the legal system (RGF93).地籍图（cadastral plan）是一份行政文书，用于确立覆盖全国领土的唯一大型宗地规划。市镇地籍图划分为若干分区，分区还可进一步细分为分区子单元，通常称为“图幅（plan sheets）”。宗地（plot）是基本地籍单元，指坐落于同一地点、归属同一权利人的独立封闭地块。矢量格式地籍图主要来源于依托与地方及区域当局签订的协议框架，对纸质地籍图或栅格式地籍图（raster）开展的数字化处理工作。法国本土的矢量格式地籍图目前均采用法定坐标系RGF93进行地理配准。
