The following information relates to CSDs compiled from adopted information and requirements where a new boundary is calculated between adopted boundary points.
Historically, a compiled plan was defined as a plan prepared from existing survey records. It was a CSD prepared without any field survey.
This dataset type was used for all classes of survey where the boundaries of a new parcel were adopted boundaries that already existed in the cadastre, or were calculated from existing points in the cadastre.
The current Rules do not use the term compiled plan.
Rules 6.3 and 6.4 specify when a boundary and boundary points are permitted to be defined by adoption or accepted.
In some cases, all parcel boundaries in a CSD will fit the criteria of rules 6.3 and 6.4 and be permitted to be adopted from existing survey records. In these cases the CSD will be a CSD of parcels without survey information (refer to Parcels without survey information below).
The Rules require that adopted information is identified as adopted [r 12.3], copied correctly [r 8.4], and that the source of the information is included [r 9.3]. Note that rule 8.4 enables an adoption to include a bearing adjustment.
The Rules do not require the notation Compiled Plan to be on the diagrams or included in the CSD.
'Parcels without survey information' is a CSD type used in Landonline.
It is a CSD where the captured marks and vectors only include boundary points and vectors between boundary points. It does not include captured non-boundary marks and associated vectors. An example where this can occur is an easement only CSD where the boundaries are computed or a mixture of computed and adopted boundaries.
Where a new boundary is calculated between two existing points, there must be sufficient vectors in the CSD to enable the relationship between the points to be ascertained and verified [r 8.1(d)].
Where these points have not been in the past linked together by a vector, verifying that the calculated relationship between the two points is within the accuracy tolerances can be problematic. Often the most appropriate proof of this relationship will be by the use of traverse adoptions which must be captured. In this case, while the boundary is a calculated boundary, the CSD type will be 'survey' not 'Parcels without survey information'.
Where a new primary parcel boundary is to be calculated between existing primary parcel boundary points:
- If the boundary is class A and the new parcel is less than 0.4 ha and comprises less than 90% of the parcel it is replacing, the existing boundary points must be defined by survey [r 6.2(a)(iv)] and witnessed [r 7.3.1(a)]. The survey must include field work because witness marks must not be adopted [r 7.3.3(a)] and PRMs are required [r 7.4.1(a)].
- For other parcels, the existing boundary points may be defined by adoption providing the points meet the accuracies specified in rule 3.3. The CSD must include sufficient vectors to ascertain and verify the relationship between the boundary points in accordance with the applicable accuracy standard [r 8.1(d)(ii)]. The use of adopted boundary vectors and, in some cases non-boundary vectors, linking these points may serve this purpose. The survey will be able to be completed without field work.
Where a new non-primary parcel boundary is to be calculated between existing parcel boundary points, the existing boundary points may be defined by adoption providing the points meet the accuracies specified in rule 3.3. The CSD must include sufficient vectors to ascertain and verify the relationship between the boundary points in accordance with the applicable accuracy standard [r 8.1(d)(ii)]. The use of adopted boundary vectors and, in some cases non boundary vectors, linking these points may serve this purpose.
In all cases, the CSD will include a CSD Plan and a Title Plan
