Geodetic strategy

The Landgate Geodetic Strategy for Western Australia to 2020 [PDF 1.2MB] provides the blueprint for the maintenance of the geodetic system. It identifies five key priorities that will ensure that our State’s geodetic system continues to evolve and serve the needs of a widening user base, which now extends to anyone with a mobile device.

The strategy is a product of industry consultation, research of other national and international geodetic strategies and the Results from the Landgate 2013 Geodetic Questionnaire [PDF 1.0MB]

1. Deliver a fit for purpose datum

Landgate, in conjunction with Intergovernmental Committee on Surveying and Mapping ICSM and Permanent Committee on Geodesy PCG, have had an active technical role in the development of the GDA2020 datum. FAQs and Information about the implementation of GDA2020 is available on the ICSM website. GDA2020 queries that are specific to the implementation by Landgate can be directed to the Landgate - GDA modernisation implementation working group by email lg-gmiwg@landgate.wa.gov.au

2. Build on Continuously Operating Reference Stations - CORS

CORS is critical infrastructure to improve positional accuracy.

Landgate operates 26 CORS across Western Australia and data from these sites is available on the Geoscience Australia (GA) ftp site. All CORS, including those operated by GA, are classified as SSMs and for convenience their site details [PDF 0.13MB] are aggregated together with the ftp download link.

3. Support ground mark users

Ground marks are vital until the transition to the GNSS is complete.

Landgate maintains an appropriate network of ground marks with the support of the stakeholders. Stakeholders can report the condition of ground marks and retrieve full reports about geodetic survey marks via Map Viewer Plus.

Please see the Geodetic survey mark information page for further details on how to use Map Viewer Plus.

4. Maintain standards

Standards are the key to geodetic system integrity.

Landgate complies with ‘Standard for the Australian Survey Control Network Special Publication 1' (SP1 v2.1) for the delivery of the states geodetic network. Stakeholder contributions to the geodetic network must also comply with these standards.

5. Future-proof the geodetic system

Research and innovation is the path to the future.

Landgate provides support for national projects and is involved in a number of research initiatives that will leverage the technology advances and provide efficiency for both government and industry. 
Landgate needs to continue monitoring global developments and trends to understand consumer demands for greater accessibility and functionality. This will ensure that the geodetic system evolves to effectively meet the challenges of 2020 and beyond.
