Computerised Cadastral Plan (PCI) in vector format — common of Montmacq- 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）系一类行政文书，旨在编制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区段，区段可进一步细分为区段子单元，通常称为“图幅（plan sheets）”。宗地（plot）是地籍的基本单元，指坐落一致且归属同一所有权人的单一闭合地块。矢量格式地籍图主要源于在与地方及区域主管部门达成的合作协议框架下，对纸质地籍图或栅格式地籍图开展数字化处理所得到的成果。法国本土的矢量格式地籍图目前均采用法定坐标系RGF93完成地理配准。
