**Please read:** This layer is part of the comprehensive Full Landonline Dataset and is designed for use only by data professionals who require the complex version of our property ownership and boundary data for advanced uses. ************************* Node can be either a physical mark or a virtual point and contains information that relates to the spatial position of that mark, its association to other marks or points, and measurements and/or calculations. Nodes may be created without being Marks (for example, an unmarked node where an instrument has been setup, a boundary point that is unable to be physically marked because of occupational obstructions etc.). Similarly, Nodes may be created prior to Reduced Observations being available. Node is the fundamental entity in the structure of topology (shapes/geometry of features/objects) to represent the cadastral survey layer and other layers in graphical form.
