WA Landgate - Private - Cadastral - Cadastral Control (Point) (LGATE-224)

This dataset contains both GESMAR (Geodetic Survey Mark Register database) survey marks and Non-Geodetic control points that are used by Landgate to maintain and improve the spatial accuracy of the Spatial Cadastral Database (SCDB) which is the official digital cadastral map base of all crown and freehold land parcels within the State of Western Australia.

Non-geodetic control points (referred to as Cadastral Control), is a set of non GESMAR survey marks that have been spatially adjusted against the GESMAR network. Connections between Cadastral Control points and cadastral marks are used to improve spatial accuracy of the SCDB.

Like cadastral point coordinates, the spatial location (coordinates) of Cadastral Control points is dynamic and may change as a result of adjustments to the GESMAR (Geodetic) network.

This dataset should not be confused with the Geodetic Survey Control (LGATE-076) layer also available in SLIP, which contains detailed information relating to Geodetic Survey Control marks (GESMAR).
