eCPD - Webinar: Subsurface Utilities and Digital Twins

Spatial Digital Twin

Date & Time

Monday, 13 Nov 2023
12:00 pm - 1:00 pm AEST

This is a recording of a webinar held on 13 May 2022.

We invite you to register for a recording of the webinar on this topical issue, with presenters Dr Craig Roberts, Senior Lecturer in Surveying/GPS/Geodesy at UNSW and Wayne Patterson Director, Spatial Operations at the NSW Department of Customer Service.

Craig will gave a short update on the revision of the Australian Standard, AS_5488 Classification of subsurface utility information in the context of datum modernisation, low-cost multi-GNSS and recent advances in positioning infrastructure in Australia. Data storage, data distribution and security are identified as challenges suggesting a reimagined data governance will be needed. Could a Spatial Digital Twin assist?

So what is a Spatial Digital Twin? Is it a BIM? Where does it come from? What is an open data policy? Who can use it? Can I use it? How? Which Datum? How accurate is the data?

Rather than just another PowerPoint webinar, Craig interviewed Wayne in a free-flowing format and asked these and many more questions. Attendees were also invited to ask their questions live in the chat as the conversation evolved.

This webinar was designed to answer your questions and is targeted at surveyors, geospatial users, students and the wider spatial community.
