Early data release

Digitisation progress and early release of data

Land Use Victoria is digitising its archive of cadastral plans and surveys for every current land parcel in Victoria as part of the Digital Cadastre Modernisation project. The digitisation process is capturing essential cadastral surveying data according to a comprehensive data model that will be used to maintain and improve the digital cadastre.

Using this approach, digital cadastral surveying data can be accessed and re-used, eliminating the need for repeated manual data capture from plan and survey images.

There are approximately 3.3 million parcels in Victoria and as of 30 June 2021, cadastral surveying data for over 2 million parcels has been digitised. Land Use Victoria is making this data available in digital format (LandXML) for early adoption and feedback.

What we are capturing in the digitisation process:

• land and road parcel dimensions (as bearings, distances, and areas)
• essential cadastral survey traverse measurements
• connections to cadastral reference marks and Permanent Marks
• bearing datum swings
• unique identifiers for all point, line, and polygon data
• administrative information, such as land parcel identifiers, Crown descriptions and local government, parish, surveyor and date of survey.

Information not being captured includes:

• easements
• location of fencing with respect to boundaries
• natural boundary dimensions
• surveyor or examiner notations.

Digitisation quality control

We are undertaking digitisation with an external supplier with quality control in two steps.

First, the data is verified by a robust, automatic validation procedure that checks the quality of data capture according to a suite of validation rules. This validation step is supplemented with random manual checking by Land Use Victoria staff to ensure overall quality standards are  achieved over the course of the project.

Second, the data is subjected to an automated least squares procedure developed by the digital cadastre adjustment supplier. This step identifies any digitisation errors which cannot be identified by the first step validation procedure and isolates any inconsistencies between multiple plans and surveys.

The result of this two-step quality control procedure is a high integrity dataset of increased spatial accuracy that will provide abiding value for the digital cadastre and the surveying profession. Although every effort is made to produce an error-free dataset, it is possible that some errors remain. For this reason users are encouraged to apply normal quality control procedures when using this data.

Digitisation progress and access

Digitisation progress is on track for completion by late 2022. The interactive map shows the current progress of digitisation and provides access to the digitised data by clicking on a highlighted Local Government Area (LGA).

Clicking on an area will display a popup text box with digitisation statistics and a hyperlink to the data.The hyperlink provides access to digitised data for each LGA bundled in a single zip file.

Digitised land parcel map

To access LandXML files we recommend using the open-source QGIS package with the LandXML plugin, or other software of your choice with LandXML enabled plugins. Other file formats will be made available over coming months.

• Click the LGA area of interest to view a pop-up card showing the percentage of parcels digitised, click on download zipfile to receive LandXML files for all parcels digitised.
• The darker the shade for each LGA area the more complete it is in terms of digitised land parcels. You can make the map larger or smaller by scrolling or using the minus or plus button in the top left corner.

Early adoption and comment

Digitised data is being made available for early adoption and comment. When the digital cadastre modernisation project is complete, data will be made available via a new Vicmap product – Vicmap Survey.  Until then, we are encouraging surveyors and spatial professionals to use this early-release data and welcome feedback on its quality and useability.
