    FME NTv2 Transformation Demonstration

    Version 1.0.0


    We put this short video together to demonstrate how efficiently data can be transformed. The Demonstration video is using a beta test version of the NTv2 distortion plus conformal grid and a custom coordinate system definition . however the process will be just the same once the official products are released.

    SSSI-WA - GDA2020 Workshop

    Introducing the New Geocentric Datum for Australia GDA2020 SSSI is proud to present a pre-conference half day seminar explaining…… Everything You Need to Know About Datums and Were Afraid to Ask. This seminar introduces the Geocentric Datum of Australia 2020 (GDA2020), which is being implemented in Australia to bring the reference system that underpins all spatial data into closer alignment with global positioning systems. Through continental drift, Australia moves at a rate of 7cm per year in a north easterly direction. This means that our current static geodetic datum, the Geocentric Datum of Australia 1994 (GDA94) represents the location of Australia in 1994 and the shift over those years to 2020 will amount to ~1.8m. New technology on the horizon will deliver accurate (3cm) real-time positioning mobile devices within the next 5-10 years and it is essential that the Australian datum is ready to support this new wave of users who have little understanding of datums, reference frames and coordinates. Target Audience Local Government and State Government Data Managers, and Surveyors wanting to learn more about GDA2020 and the dynamic datum. Provisional Program 2.00 -2:30 Geodetic Datum Fundamentals - Linda Morgan 2:30 –3:00 The Role of ICSM, Landgate and WALIS during the transition to GDA2020 – Kent Wheeler, Geodesist, Landgate 3:00- 3:30 GDA2020 Main Roads Survey - Ray Watson, Senior Geodetic Surveyor, Planning and Technical Services, Main Roads 3:30 – 5:00 Panel Discussion: Panellists – Linda Morgan, Irek Baran, Kent Wheeler, Jenny Smith (WALIS), Ray Watson. Q&A facilitated by Lesley Arnold, Geospatial Frameworks. What you will learn: · What is the Geocentric Datum of Australia – GDA2020 · How will it impact geospatial business systems · However will; the future dynamic datum be managed · ISCM tools for GDA2020 implementation · How agencies are preparing for the change and what you need to do now · Why ignoring the change is a risks to future business · Contact persons for more information Places are limited for this workshop so register here ASAP. DATE: THURSDAY 12th October 2017 TIME: 2:00pm to 5:00pm VENUE: Training Room, Bayswater Town Council, 61 Broun Avenue, Morley. Parking is available onsite. COST: SSSI Members: FREE registration to those attending the WA SSSI Regional Conference on 13th October 2016 SSSI Members/Alliance Members: $40 for Workshop Only Non-Members: $195 for Workshop Only REFRESHMENTS: Lunch provided from 1:00 – 2:00pm; Coffee/Tea Provided WHO SHOULD ATTEND: Spatial Science professionals wanting to learn how the new Geocentric Datum will impact data management and service delivery.

  5. Both the 7 parameter (Helmert) transformation parameters and the values for the 14 parameter transformation have been published by way of a GDA2020 Interim Release Note. These parameters allow conversion between GDA94, GDA2020 and ITRF 2014. The spreadsheet linked below is primarily for demonstrating the Landgate Project Grid Projections used in Western Australia. However it also has some embedded functions that utilize the published 7 parameter transformation parameters to convert between AGD84, GDA94 and GDA2020. https://www0.landgate.wa.gov.au/business-and-government/specialist-services/geodetic/related-documents/Geodetic-Calculations-v3.xlsm

    Landgate Project Grids

    For many years Landgate has published project grids on the form of Mercator projection parameters. These project grids have become a common standard for the interchange of data for engineering, surveying and mapping projects. Most grids have definitions in AGD84, GDA94 and GDA2020. The parameters for these project grids are on the Landgate Webpage. These Project Grid parameters have also been included in Ver 9.0.1 release of the on-line EPSG registry.
