During this stage, the information contained in registered plans and cadastral surveys will be turned into digital files. This includes documents like abstracts of field records and surveyor’s field notes, some dating back to the 1860s.
By the end of 2021, more than 800,000 plans and surveys describing 3.3 million parcels of land will be back captured.
Information related to both freehold and Crown land parcels is being captured.
The data is being stored in LandXML format. Each LandXML is being checked for capture accuracy and completeness through automated validation. Manual assessment of randomly selected plans and surveys helps to ensure the quality of the information being processed.
Data from each LandXML is then being consolidated within a central database to form a comprehensive, contiguous digital cadastre dataset that will be used to maintain the digital cadastre in perpetuity.

Digitising the data held in plans and surveys requires skill and familiarity with Victoria’s cadastral system. The project team has set up a Technical Forum of experienced staff from Land Use Victoria, including the Surveyor-General of Victoria.
Its role is to discuss and resolve any queries raised by the external back capture provider. These are usually focused on how to interpret survey plans –not surprising, given some are more than 150 years old.
Back capture schedule for Victoria
Each week on average 20,000 parcels are being digitised from the hard copy plans and surveys. The work is being completed by Local Government Area (LGA) following the schedule shown in the map below.
What data is being captured in Stage 1 Back capture?
The data that is manually captured from the plans and associated surveys includes:
- the dimensions (bearings and distances) of the parcel and the parcel identifiers (lot numbers etc)
- survey traverse measurements, including connections to the survey control network
- title connections of the parcels to a road corner or Crown boundary
- the geographic coordinate system of the plan or survey
- plan administrative information such as the Local Government Area (LGA), plan numbers and Crown descriptions.
- the “Date of Survey” and the “Date of Registration” of the plan
- survey reference marks and monuments
What is not being captured?
- undimensioned ambulatory boundaries related to rivers, lakes and coastlines. In this context, other input formats (such as imagery and Vicmap property) will be used to upgrade the digital cadastre.
- non-dimensioned parcels
- units, townhouses, buildings and other 3D structures
- fences, kerbs, channels and other physical features
