Cadastral plots — Département du Loiret — June 2019

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 cadastral section is a part of the communal territory whose perimeter is usually made up of boundaries of a relatively stable nature on the ground (road, roads, watercourses, etc.). The plot is the basic cadastral unit. It is a single-contained plot located in the same place and owned by the same owner. Cadastral plans in vector format in metropolitan France are currently georeferenced in the legal system (RGF93) using “conical 9 zones compliant” projections. Georeferencing of vector plans could be obtained: * when they are made (in the case of very recent cadastral plans); * after transformation of their coordinates expressed in the Lambert zones projection; * during vectorisation (cases not initially georeferenced)
