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 use of a monumentation CSD provided for in rule 11, the associated exemptions from the usual requirements of the Rules, and the content and capture requirements for this CSD type.

A monumentation CSD is a boundary marking survey office (SO) CSD that records in the cadastre the placement of a boundary mark in the position of a previous boundary mark or boundary point. This type of CSD is recorded in Landonline as a Boundary Marking – Monumentation CSD.

Monumentation CSD use

Authoritative information on monumentation CSD

Despite the reduction in information required in a monumentation CSD, the CSD must still be certified [r 13] and must comply with the relevant rules [s 9(a) Cadastral Survey Act 2002].  The information is therefore authoritative.

The historic 'approval for record purposes' option is not available.

When monumentation CSD must not be used

A monumentation CSD must not be used:

Each position to be defined by survey on monumentation CSD

Each boundary position that is marked and recorded in a monumentation CSD must be defined by survey [r 6.2(v)].  This means that all evidence must be used to determine its correct position [r 6.1].

Boundary point must exist in cadastre for monumentation CSD

A monumentation CSD must only be used to record the placement of a new mark at an existing boundary point [r 11.1(a)].  

The placement of a line peg on an existing boundary where the point is not already recorded in the cadastre must be recorded in a boundary reinstatement CSD.

Boundary point must be class A or B for monumentation CSD usage

A monumentation survey must only be used where the point is a class A or class B boundary point [r 11.1(a)(i)].

Non boundary mark and boundary point from same CSD for monumentation CSD

For the purpose of a monumentation survey, the boundary mark must be placed in terms of an old non-boundary mark [r 11.1(a)(ii)]. The old non-boundary mark does not need to have the attributes of a witness mark [r 11.2(c)].

The boundary point and the old non-boundary mark must have been previously recorded in the same CSD and that CSD must have been fully approved as to survey [r 11.1(a)(iii)].  

Where the CSD that records the old survey mark did not find, place, or reinstate the boundary mark or point, then rule 11.1(a)(iii) has not been met.  In this case, a boundary reinstatement CSD will need to be lodged and will include the adoptions used to determine the relationship between the old survey mark and the boundary point.

Marks that are only recorded on datasets 'approved for record purposes only' must not be used.

Accuracy between existing marks for monumentation CSD

The existing accuracy between the boundary point and the old non boundary mark must meet the boundary witnessing accuracy standard specified in rule 3.6 [r 11.1(a)(iv)] before a monumentation CSD can be used.

Monumentation CSD rule exemptions

Rule 11.2 specifies a number of exemptions for a monumentation CSD, including exemptions from the requirement to:

  • be orientated in terms of an official projection [r 4.1(a)],
  • connect to a cadastral survey network mark [r 4.2],
  • connect to witness marks [r 7.3],
  • connect to PRMs [r 7.4],
  • include a CSD Plan in accordance with rule 9 [r 8.1(a)].  A CSD Plan is required in terms of rule 11.3,
  • include vectors in the CSD to ascertain and verify the relationship between all marks [r 8.1(d)].  One or more vectors are required on the Diagram of Survey [r 11.4.1(d)],
  • include a minimum of two vectors for each mark [r 8.1(e)],
  • include a survey report [r 8.2].

Content of a monumentation CSD

A monumentation CSD includes diagrammatic and non-diagramatic information in a CSD Plan (refer to Content of a boundary marking SO CSD).

Diagrammatic information

In a monumentation CSD, the Diagram of Survey must include:

  • the old non-boundary mark and the new boundary mark [r 11.4.1(a) and (c)].  Other marks (including traverse marks) used in the survey may be, but are not required to be, depicted,
  • at least one vector between the non-boundary mark and the new boundary mark [r 11.4.1(d)].  This vector may be measured or calculated,
  • parcel appellation information for adjoining parcels [r 11.4.1(b)],
  • mark types (other than a peg or post) [r 11.4.2(a)] and names [r 11.4.2(b) and (c)], and
  • a north point [r 11.4.3(c)].

Non-diagrammatic information

In a CSD Plan for a monumentation CSD, information which is not required to be represented diagrammatically includes:

  • the surveyor's certification [r 11.3(b)(i)],
  • information on the horizontal datum and circuit used in the survey [r 11.3(b)(ii)],
  • the CSD reference of the approved CSD refered to in rule 11.1(a)(iii) [r 11.3(b)(iii)], and
  • occupation information [r 11.3(b)(iv)] (refer to occupation and physical features).  

In a CSD Plan, the non-diagrammatic information may be included on the Diagram of Survey.  Its inclusion on the diagram satisfies rules 11.3(b)(i) – (iv).

Landonline capture of a monumentation CSD

For a Boundary Marking - Monumentation CSD, the following are the minimum Landonline capture requirements:

  • all new boundary marks must be captured (the non-boundary mark/s used to set out the boundary mark need not be captured)
  • the CSD must be connected to at least two nodes existing in Landonline, and
  • the nodes must be connected by non-boundary vectors.

Upon capture of this information, Landonline requires an image to be produced in the CSD Plan using the plan generation functionality.  This image becomes part of the Diagram of Survey. 

In addition to these capture requirements, Rules 11.3 and 11.4 specify some additional information that has to be included on a Diagram of Survey (eg the old non-boundary mark, and vectors joining it to the boundary mark; adjoining appellations).  These requirements can be satisfied either by using Landonline capture functionality, or by attaching a ‘survey data graphic’ supporting document.  In most cases there would be little difference between the information required to be captured and the information required by the Rules to be in the CSD.

Where a survey data graphic has been added there will be two plan images comprising the Diagram of Survey – the one generated by the Landonline plan generation functionality, plus the survey data graphic.

Additional information in monumentation CSD

Other non-mandatory information may be included in the monumentation CSD.  Examples include adoptions, survey marks, and 'traverse' vectors related to the boundary marking survey. Note that this additional information must be consistent with all other information required by the Rules.

This information can be provided using either a ‘survey data graphic’ supporting document or by using the normal capture and plan generation functionality in Landonline.

Where the survey data graphic has been added there will be two plan images comprising the Diagram of Survey – the one generated by the Landonline Plan Generation functionality, plus the survey data graphic.
