  2. You can use AusDatumTool. This a really convenient way to convert between GDA94 and GDA2020 that uses the 7-parameter similarity transform. It supports both interactive and conversions of text files in formats such as CSV. See https://www.binaryearth.net/AusDatumTool

    AusDatumTool

    I've developed a tool for Windows called AusDatumTool which is a really convenient way to convert between GDA94 and GDA2020 that uses the 7-parameter similarity transform. It supports both interactive and conversions of text files in formats such as CSV. See https://www.binaryearth.net/AusDatumTool
  4. Hi All I was looking to get some feedback on what would be best practice in a GDA2020 transformation when it comes to aerial photography datasets. Currently our organization's aerial imagery is on MGA Zone 55 (GDA94). A vicmap bulletin (27 February 2018 - https://www2.delwp.vic.gov.au/__data/assets/word_doc/0027/116919/VicmapBulletin-GDA2020.docx ) stated: "While raster imagery is stored in its capture datum (and generally, transformations are avoided as they introduce errors)..." - I was wondering if this would be the recommended approach for our organization (ie. not transform the aerial photography data)? And what are the reasons for the best-practice approach?
  5. Landgate has committed to change its systems and update datasets to take advantage of the GDA2020 datum. This will happen in a staged approach.

    Please see the latest update from SAFE on this issue - https://knowledge.safe.com/questions/67350/why-do-i-get-warning-and-assumed-default-when-tran.html looks as though we will be good to go in the 2019 release, which should be imminent.
