Importance of a datum
Enables integration of different datasets, measure once, use multiple times

National implementation
GDA2020 is now Australia’s official national datum• Published in Commonwealth Legislation as:
National Measurement (Recognised Value Standard of Measurement of Position) Determination 2017
• GDA2020 is Australia’s official datum, revoking GDA94
• Effective from 11 October 2017
![Page 13: Core spatial data services roadshow€¦ · • Offshore Petroleum and Greenhouse Gas Storage Act 2010 • Mineral Resources (Sustainable Development) (Mineral Industries) Regulations](https://reader033.vdocuments.net/reader033/viewer/2022060511/5f283fed05141e5ea43b3d73/html5/thumbnails/13.jpg)

GDA2020 drivers
Drivers to adopt a modernised geodetic datum for Australia:
• Plate tectonics and regional deformation
• Alignment with global satellite positioning systems - ITRF
• Significant positioning technology developments
• GDA94 failing to support increasing accuracy needs of users
• Widespread distortions in GDA94
![Page 14: Core spatial data services roadshow€¦ · • Offshore Petroleum and Greenhouse Gas Storage Act 2010 • Mineral Resources (Sustainable Development) (Mineral Industries) Regulations](https://reader033.vdocuments.net/reader033/viewer/2022060511/5f283fed05141e5ea43b3d73/html5/thumbnails/14.jpg)
14
GDA2020 specifications
• Geocentric Datum of Australia 2020
• Conventional static datum like GDA94 with rigorous uncertainty
• Just like GDA94 — based on ITRF, fixed at a specific epoch:
GDA94 = ITRF1992 @ 1994.0
GDA2020 = ITRF2014 @ 2020.0
• Horizontal shift of approx. 1.6 m NE from GDA94, slightly rotated
• Consistent vertical drop of 0.09 m from GDA94
• AUSGeoid2020
• Projections: MGA2020 (UTM), VICGRID (conformal conic)
• Australian Terrestrial Reference Frame (ATRF), initial release commencing January 2020

Introduction
• Victoria’s official state-wide planning zone & overlay service
• Introduced to replace traditional PDF maps and Planning Maps Online website
• One of the many tools available on the new Planning website
• Utilises Esri ArcGIS technologies to provide an intuitive and powerful interface for our wide range of users

Our Situation
• Victorian Planning Scheme is extremely complex to manage
• 82 Schemes across each Municipality
• 49,055 Planning Zones polygons (across 44 Zones)
• 78,656 Planning Overlays polygons (across 25 Overlays)
• 3,554,461 Properties across the state
• 3,718,382 Parcels across the state
• Weekly amendments are submitted by Municipalities
• Weekly changes to the underlying Cadastre

Key Problems
• Old Technology Stack
• Couldn't utilise new features and technologies
• No Topology rules available to us
• Maintaining 15,000 PDF’s as the authoritative dataset
![Page 59: Core spatial data services roadshow€¦ · • Offshore Petroleum and Greenhouse Gas Storage Act 2010 • Mineral Resources (Sustainable Development) (Mineral Industries) Regulations](https://reader033.vdocuments.net/reader033/viewer/2022060511/5f283fed05141e5ea43b3d73/html5/thumbnails/59.jpg)

Implementation
• Assessment of the available technologies
• Consolidation of the Planning Scheme to facilitate better management
• Implementation of quality assurance processes for automated validation and cleaner data
![Page 60: Core spatial data services roadshow€¦ · • Offshore Petroleum and Greenhouse Gas Storage Act 2010 • Mineral Resources (Sustainable Development) (Mineral Industries) Regulations](https://reader033.vdocuments.net/reader033/viewer/2022060511/5f283fed05141e5ea43b3d73/html5/thumbnails/60.jpg)

New Weekly Process
• Automated process executed each week
• Utilises FME and Python technologies
1. Import new Cadastre dataset
2. Automatically run validation scripts across Planning Scheme
3. Review newly introduced alignment exceptions
4. Update where applicable
5. Run QA scripts to ensure no error introduced
6. Publish updated Planning Scheme
