Computerised Cadastral Plan (PCI) in vector format — common from Bailly- 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）属于行政文书，是覆盖全国领土的唯一大比例尺宗地规划图。市镇地籍图可划分为若干分区，分区还可进一步细分为分区子单元，通常俗称‘图幅（plan sheets）’。宗地是基本地籍单元，指坐落于同一地点、归属同一权利人的单一封闭地块。矢量格式（vector format）地籍图主要源自依托与地方及区域主管部门签订的协议，对纸质地籍图或栅格式地籍图开展数字化处理的成果。当前法国本土的矢量格式地籍图均采用法定坐标系（RGF93）完成地理配准。
