Contributing to a smarter Victorian cadastral system.

This project aims to modernise the Victorian land administration system (LAS) by conceptualising, designing, developing and maintaining a suite of innovative tools and services. This project develops the required infrastructure for collecting, creating, validating, visualising, lodging, sharing and accessing the spatially accurate multi-dimensional cadastral data required by the Victorian land administration stakeholders for different purposes such as planning, development, subdivision, asset/infrastructure management, transport, disaster management and smart cities.

The expected outcomes of this project include ongoing maintenance of existing ePlan services (eg: validation, visualisation, visualisation enhancement tool and data storage), development of new ePlan services (eg: data viewer and CAD to LandXML conversion service), support to land administration stakeholders and demonstrating the benefits of ePlan, collaboration with other states on ePlan infrastructure and services, collaboration on Digital Cadastre Modernisation Program, supporting building subdivision plans in ePlan, and development of a roadmap for Victoria’s 3D digital cadastre.

The ePlan project benefits the Victorian land administration system (LAS) stakeholders because it:

  • Provides a standard data exchange format for cadastral data sharing among LAS stakeholders
  • Provides a workflow for exchange of digital cadastral data among LAS stakeholders
  • Enables the LAS stakeholders to re-use the existing digital cadastral data for different purposes, such as re-establishing subsequent surveys, updating databases and populating data into other systems
  • Provides spatially accurate input data for updating the Victorian Digital Cadastre
  • Provides the LAS stakeholders with the spatially accurate cadastral data required for different applications such as planning, development, subdivision, asset management and disaster management
  • Improves the quality of cadastral plan and survey data through validation checks
  • Standardises the presentation of cadastral plans through visualisation service
  • Improves access to/delivery of cadastral and survey information
  • Assists with improved digital plan examination/checking process
  • Reduces errors, anomalies and requisitions in cadastral plans and surveys
  • Improves cadastral plans examination and registration turnaround times.
