Since its launch in 2001, Geoscience Australia's online positioning service (AUSPOS) has continued to be a widely used tool for the online processing of geodetic GPS data for surveying, mapping, geodetic, geophysical, hydrographical, military and other applications. On 20 March 2011, Geoscience Australia released an updated version of the service, AUSPOS2. This update implements recent advances in analysis software and strategies, the reference frame ITRF2008, AusGeoid09 and the latest transformation parameters between ITRF2008 and GDA94. AUSPOS2 now delivers ITRF2008 coordinates with an uncertainty less than 10 millimetres to users within 3-5 minutes while continuing to provide Australian users access to GDA94 coordinates and derived AHD heights to the highest achievable accuracy. This talk will overview the AUSPOS2 system and how users can best exploit this free service.

This record contains the raw Ground Penetrating Radar (GPR) data and scanned field notes collected on fieldwork at Adelaide Metropolitan Beaches, South Australia for the Bushfire and Natural Hazards CRC Project, Resilience to Clustered Disaster Events on the Coast - Storm Surge. The data was collected from 16-19 February 2015 using a MALA ProEx GPR system with 250 MHz shielded, 100 MHz unshielded and 50 MHz unshielded antennaes. The aim of the field work was to identify and define a minimum thickness for the beach and dune systems, and where possible depth to any identifiable competent substrate (e.g. bedrock) or pre-Holocene surface which may influence the erosion potential of incident wave energy. Surface elevation data was co-acquired and used to topographically correct the GPR profiles. This dataset is published with the permission of the CEO, Geoscience Australia.

This record contains the raw Ground Penetrating Radar (GPR) data and scanned field notes collected on fieldwork at Old Bar and Boomerang Beaches, NSW for the Bushfire and Natural Hazards CRC Project, Resilience to Clustered Disaster Events on the Coast - Storm Surge. The data was collected from 3 - 5 March 2015 using a MALA ProEx GPR system with 250 MHz shielded and 100 MHz unshielded antennaes. The aim of the field work was to identify and define a minimum thickness for the beach and dune systems, and where possible depth to any identifiable competent substrate (e.g. bedrock) or pre-Holocene surface which may influence the erosion potential of incident wave energy. Surface elevation data was co-acquired and used to topographically correct the GPR profiles.

The AMSIS Distance To tool calculates the distance to a selected marine feature. The output is the distance to the nearest feature from the given location.

Data collected from Geodetic GPS observation campaigns over the last 15 years. This data set is from non-continuous GPS sites. It is a combination of surveys undertaken by Geoscience Australia, State collaborators and international collaborators.

Data collected from the Australian Regional Global Navigation Satellite System (GNSS) network, AuScope network and other GNSS observatories located around the world over the last 15 years.

This report details the results of the 2017 Australian GNSS CORS Position Verification Analysis that has led to the creation of certificates of verification of the reference standard of measurement for position in accordance with Regulation 13 of the National Measurement Regulations 1999, National Measurement Act 1960. Our analysis of the Asia Pacific Reference Frame (APREF) CORS stations located on the Australian Plate has been aligned to a set of extended 109 Australian Fiducial Network stations with recognized value standard for position in Australia with Geocentric Datum of Australia (GDA2020) coordinates (refer to National Measurement Act 1960 - Recognized-value standard of measurement of position determination 2017 F2017L01352 https://www.legislation.gov.au/Details/F2017L01352 ). GDA2020 coordinates and uncertainties are reported.
