Recording marks and points
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.

Recording adopted marks and points on the Diagram of Survey
On a Diagram of Survey, adopted 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.

Recording disturbed marks on the Diagram of Survey
On a Diagram of Survey, disturbed marks are depicted with 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 for these marks.
| Disturbed Marks | New Mark type | Original ID | New ID | Origin CSD ref | Symbol | Notation | Example |
|---|---|---|---|---|---|---|---|
| Disturbed non-boundary mark | ✓ | If it exists | ✓ | ✓ | new | disturbed | IS 3 (VI DP214 Dist) |
| Disturbed boundary mark | if it exists | ✓ | new | disturbed | (XV DP 214 Dist) (DP 214 Dist) |
Recording renewed marks and points on the Diagram of Survey
On a Diagram of Survey, renewed marks 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 required for these marks.
| Renewed Marks | Old mark type | New mark type | Original ID | New ID | Origin CSD ref | Symbol | Notation | Example |
|---|---|---|---|---|---|---|---|---|
| Renewed non-boundary mark, now a witness mark for the purpose of the survey | ✓ | ✓ | if it exists | ✓ | ✓ | old | renewed | IT 4 (IS VI DP214 ren) |
| Renewed boundary peg or post | ✓ | if it exists | ✓ | old | renewed | (Peg DP 214 ren) IS (Peg DP 214 ren) | ||
| Renewed boundary mark (other than peg or post) | ✓ | ✓ | if it exists | ✓ | old | renewed | IS (LP DP 214 ren) | |
| Old peg renewed IT, now a PRM for the purpose of the survey | ✓ | ✓ | if it exists | ✓ | old | renewed | IT 5 (peg DP 254) |
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.
