1. What is the Single CAD Format File (SCFF)?

The Single CAD Format File (SCFF) is about supplementing Victorian cadastral plans and surveys lodged in SPEAR with an agreed CAD file, which through engagement and collaboration with the surveying industry, has defined structured cadastral CAD layers, adopting the Drawing Exchange Format (DXF) version 2010.

2. Why use the SCFF?

There are three reasons for adopting the SCFF.

Firstly, promotes industry standards and consistency in CAD files that supports cadastral plans and surveys that are supplied in SPEAR.

Secondly, facilitates immediate efficiencies in the updating of Vicmap for PDF plan applications in SPEAR, whereby the Vicmap maintainer is handling the same type of CAD file in the supply of Digital Survey Geometry data, with provision to automate some processes.

Thirdly, creating 2D ePlan applications in SPEAR by uploading the SCFF into a CAD to ePlan Creation service, which converts the SCFF to an ePlan LandXML file. LUV aims to launch this new ePlan tool in early 2021 to enable the creation of 2D ePlan subdivisions.
Work is also underway in the Digital Cadastre Modernisation Program to automate the update of the digital cadastre when 2D ePlan subdivisions are lodged in SPEAR and subsequently registered at LUV.

3. What are the defined cadastral layers in the SCFF?

There are 73 cadastral layers in the SCFF defining boundary, textual and survey information, which include:

Boundary parcels and lines layers:
Lots, stage lots, reserves, roads, common properties, easements, services of crown land, restrictions, administrative boundaries, crown allotments, crown portions, building boundaries, building returns, connections, splays, offset, unsurveyed and natural boundaries.

Textual labels and descriptions layers:
Lots, stage lots, reserves, roads, common properties, easements, services of crown land, restrictions, crown allotments, crown portions, control marks.

Survey layers:
Traverse lines, radiations, traverse points, control marks, and reference marks.

4. Does the SCFF support all cadastral applications in SPEAR?

Yes, all PDF cadastral applications in SPEAR are supported by the SCFF. This includes the site / ground level of 3D plans, but not upper and lower boundaries and cross-sections.

Where a layer isn’t defined in the SCFF, there is provision to include layers in addition to the 73 cadastral layers. For example, defining occupation.

The SCFF will also support 2D ePlan subdivision applications in SPEAR when the ePlan Creation service (SCFF to ePlan) becomes available, which converts the SCFF to a LandXML file, ready for uploading to the ePlan application in SPEAR.

The SCFF doesn’t support abstract of field records however, where applicable, connections to MGA is required.

5. Must the SCFF include connections to MGA?

Yes, the SCFF must be connected to MGA using the survey related CAD layers, ie. control marks, reference marks, traverse points, traverse lines, and radiations. This is in compliance with the Victorian Cadastral Surveys Practice Directives and Digital Survey Geometry (DSG) requirements.

6. Can the SCFF be changed / modified?

Layers names in the SCFF must not be changed. Not adhering to the layers name will result in supplying an invalid SCFF.

Other changes to the layer structure are not recommended as they may result in:

  • Validation issues / delay in the updating of Vicmap,
  • Possible omissions of cadastral data during the future conversion process using the ePlan Creation service (SCFF to ePlan).

There is provision to include layers in addition to the 73 cadastral layers. For example, defining occupation.

The order of the layer structure is encouraged however there is provision to reorder the layers in your order of preference.

7. What is the cost to use SCFF?

The SCFF is not a product, it is a template for the CAD file that is being defined by Land Use Victoria to support the Victorian cadastre. It is free to use/adopt, and available in SPEAR.

8. Is it mandatory to use the SCFF?

It is not mandatory to use the SCFF. Land Use Victoria encourages its adoption as it will improve the updating processes of Vicmap, and the uptake of ePlan to facilitate improvements in plan examination and registration processes and automation of updating the Digital Cadastre.

9. How is the SCFF used in preparing cadastral plan drawings?

To commence drawing a plan using the SCFF, download the guidance notes and instructions and SCFF template, which has the defined cadastral CAD layers, and adopt the template in your drafting processes.

Examples of CAD drawn plans of subdivisions and other common cadastral plan types will be made available here.

10. How is the SCFF supplied in SPEAR?

For PDF plan applications that are not ePlan, to supplement the PDF plan in SPEAR, the SCFF needs to be supplied as a Digital Survey Geometry file. SPEAR has current functionality to supply the Digital Survey Geometry file directly in SPEAR for all PDF plan applications.

For ePlan applications, the SCFF must be uploaded to the ePlan Creation service (SCFF to ePlan), which is currently under development. The new tool will convert the SCFF to a LandXML file, ready for uploading to the ePlan application in SPEAR. A validation report and a visualised PDF plan, which can be enhanced, is automatically generated when the LandXML file is uploaded in SPEAR. Note, the SCFF is not required in SPEAR for ePlan applications.

11. Is it possible to confirm the SCFF has been correctly setup?

A CAD Validation Service is going to be made available on the SPEAR website very soon that can be used to confirm the correct CAD format and layers have been correctly setup.

12. Is the SCFF validated in SPEAR?

For PDF plan applications, SPEAR does not have current functionality to validate the SCFF.

For ePlan applications, the SCFF will be validated when the file is uploaded to the ePlan Creation service (SCFF to ePlan). The SCFF is validated for the following:

  1. The CAD file must be the valid format and version of DXF
  2. At least one of the standard geometrical CAD layers must have a feature.
  3. Layers must have the expected feature types (ie. point, line, polygon, text).
  4. Each closed parcel needs to have only one corresponding identifier label in its relevant layer.
  5. Where easements / crown land services overlap, the overlapping part must have only one corresponding identifier label in its relevant text layer.
  6. The insertion point (lower left corner) of PM / PCM nine figure number text should be positioned exactly on the PM / PCM point coordinate.
  7. Parcel identifiers must follow the expected naming convention.

13. What measurements are supplied?

Measurements must be supplied as “ground measurements”.

14. Is there ability to supply provisional plans when submitting ePlan applications in SPEAR?

Yes, a provisional plan can be generated from the ePlan Portal prior to formally creating the ePlan application in SPEAR.

15. How is the surveyor’s identity protected when creating an ePlan application in SPEAR?

When the LandXML file is visualised by the ePlan visualisation service, SPEAR watermarks the company logo of the surveyor’s firm on the visualised PDF plan.

16. Do I need to show parcel dimensions in the SCFF?

No, dimensions are not required in the SCFF.

17. Where can I send feedback?

If you have any comments or suggested enhancements on the SCFF, please email the SPEAR Service Desk at fcrne.vasb@qryjc.ivp.tbi.nh
