On the 28th and 29th of November the GDA Implementation Working Group met and released some key communications about the datum. They are as follows: Continue reading
In my last discussion I introduced the topic of the new GDA2020 datum, the reasons behind it and how Esri intends to implement support for this new geodetic datum. Now that the impending initial release of the first set of parameters is due shortly and with the NTv2 grid due before the end of the year, I thought it important, that as an organisation, it is time consider how do you go about planning the move to this new datum.
Recently in the Australian media there has been a lot of commentary around the impending update to Australia’s primary datum. From GDA94 to GDA2020. It has even made the British media http://www.bbc.com/news/technology-36912700.
At Esri Australia this has prompted a lot of questions from clients in regards to the support of the new datum GDA2020 in ArcGIS. Will ArcGIS support GDA2020 and when will ArcGIS support GDA2020?
Before we start to answer these questions I think it is important we understand exactly what the new datum is and why Geoscience Australia is moving towards a new datum.
