Note: this guideline is issued by the Surveyor-General under section 7(1)(ga) of the Cadastral Survey Act 2002 about the Rules for Cadastral Survey 2010 and is not legally binding.

The following information relates to the recording of survey mark and point information and symbols in CSDs.

The primary evidence of boundary location (ie. boundary points and marks) must be recorded in a consistent and appropriate manner.  This ensures that the information is correctly located and referenced in the cadastre and that future users can interpret the information correctly.

Recording new marks and points on the Diagram of Survey

On a Diagram of Survey, new marks and points are depicted with the symbol types specified in rule 12.2 and survey mark and point information specified in rule 9.6.2.  The following table illustrates the information requirements for these marks and points.

Historically, identifiers were required for boundary points.  While this is no longer the case, they can be added to the CSD if the surveyor considers they will enable the data to be more easily interpreted (shown as optional in the table below).

A reinstated mark is treated as a new mark.

Exceptions to depicting boundary points on the Diagram of Survey

Boundary points on an existing easement boundary not severed by the creation of a new underlying boundary are not required to be shown on a Diagram of Survey [r 9.6.3(f)(ii)].

Refer to Vectors not required for unaffected non-primary parcel on a Diagram of Survey

Boundary points of boundaries accepted under rule 6.3(c) are not required to be shown on a Diagram of Survey [r 9.6.2].

Refer to Boundary information in the CSD for parcels over 100ha

Name of control marks on the Diagram of Survey

Where the mark is from the national survey control system, the mark's name from that system must be used [r 9.6.2(i)].

Note: the geodetic code is not part of the name for CSD purposes although it may be included on the diagram.
