  1. Today (7/6/2018) Landgate has upgraded its geodetic system (GOLA) to support both GDA2020 and GDA94 coordinates. The geodetic marks can be accessed via Map Viewer Plus by selecting ‘Geodetic’ from the Layer List. This new service will eventually replace Locate. Please note Landgate continues to provide other options to access geodetic marks’ information. For example, you can download Google Earth KML zip file containing a link to all geodetic marks or access them via data.wa.gov.au. Users of the MyLandgate Survey channel are still able to access the geodetic mark information via this portal. For more detailed information on how to access Landgate’s geodetic marks information please visit our website.
  2. A good article from a software providers perspective on the new USA Terrestrial Reference Frames that will replace the existing plate-fixed datums in 2022 http://blog.bluemarblegeo.com/2017/09/05/north-american-terrestrial-reference-frame-2022-replacing-nad83/?aid=EMMN0917&utm_source=newsletter&utm_medium=emil&utm_campaign=september_2017&utm_content=button .
