Since 1994 Australia has moved 1.8 metres due to plate tectonic motion. The GDA2020 is the latest set of coordinates available for organisations to use that provides closer alignment to the Global Navigation Satellite System (eg. GPS). We welcome Director of National Geodesy at Geoscience Australia, Nick Brown to break down what is GDA2020, how will it effect us and what we need to know to be prepared for the changes.
1:05 Nick, could you tell us about yourself and your role at Geoscience Australia?
1:50 Can you tell us a bit about the ICSM (Intergovernmental Committee on Surveying and Mapping)?
3:10 Can you explain what a datum is and why it is important?
3:50 So why do we need a new datum?
7:45 Is GDA2020 a dynamic datum?
8:52 Do organisations have a choice between using a static or dynamic datum?
9:55 Why is the ATFR being introduced? Which industries and applications will benefit most from this change?
11:54 With GDA2020 being a fixed datum will the change for organisations be similar to back in 2000 when Australia updated from AGD84 to GDA94?
13:00 What are the benefits of adopting the GDA2020?
15:45 What are the repercussions of not using the GDA2020?
17:27 Is there a cut off time for the update to the GDA2020 to be made?
18:30 Where can people go if they want to find out more about the GDA2020?
