This record contains the processed Ground Penetrating Radar (GPR) data (.segy), field notes, and shapefile 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.

The Criteria Assessment tool takes the input path or area created by the user and the input variables chosen to generate a heat map surface, KML surface, KMZ surface and PDF Report. This service is specifically for use within the Carbon Capture and Storage application.

The Identify_Tool service includes the key set of infrastructure layers included in the LeastCostPath and ClipAndZip geoprocessing tools. The indentify query uses a dynamic tolerance and returns features including geometry as JSON.

The Clip and Zip tool takes an input polygon extent as WKT input and clips required featureclasses listed. The data is referenced from its own database with all layers projected to 4326 spatial reference. The output is a zipped file geodatabase with a copyright text file included.

The Print Service provides PDF map prints via an online interface. This service prints detailed PDF maps, including scale bar and marginalia.

<div>The Pacific Islands Applied Geoscience Commission (SOPAC) requested Geoscience Australia to compute International Terrestrial Reference Frame (ITRF) coordinates for 18 survey sites on islands in the northern Fiji archipelago from continuous geodetic GPS measurements observed from 8th July to 5th August 2008 inclusive. The GPS data was processed using version 5.0 of the Bernese GPS Software in a regional network together with selected IGS sites. The GPS solution was constrained to the ITRF2005 reference frame through adopting IGS05 coordinates on selected IGS reference sites and using the final IGS earth orientation parameters and satellite ephemerides products.</div><div>These coordinates provide the coordinate reference frame to be used to define Fiji’s claim to extended continental shelf under the provisions of Article 76 of the United Nations Convention on the Law of the Sea.</div><div><br></div>

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.
