  • This dataset was produced by a NESP project, and contains 5 m resolution bathymetry tiles with national Australian coverage of both coastal and outer marine regions. The data product contains 'bathymetry' and 'shelf bathymetry', with the shelf bathymetry constrained to the 0-200m depth region. Files are in RGB geotiff and ASC grid format, zipped as *.gz. Tiles are 0.5x0.5 degrees.

    Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the Murrindal, Vic, 1996 VIMP Survey (GSV3060) survey were acquired in 1995 by the VIC Government, and consisted of 15589 line-kilometres of data at 200m line spacing and 80m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

  • <p>The current coexistence framework for the Woomera Prohibited Area (WPA) was established in 2014; it seeks to balance the interests of all users in the Area. Under this framework, the Department of Defence is the primary user of the WPA for the testing of weaponry and related war materiels. Access to the WPA by a range of non-Defence users, including Aboriginal groups, the resources sector, pastoralists and tourists, is also provided for. The coexistence framework is being reviewed in August 2018. <p>As part of this 2018 WPA Review, Geoscience Australia, together with the Office of the Chief Economist, has undertaken the following tasks: <p>• Updated the current understanding of the region’s geology; <p>• assessed the known Economic Demonstrated Resources (EDR) and potentially undiscovered mineral and petroleum resources (including critical commodities) and groundwater; <p>• documented resource exploration activities in the WPA; and <p>• provided an economic assessment of the known mineral resources and possible future mine developments in the WPA. <p>An assessment of the potential for undiscovered mineral and petroleum resources has been conducted by considering the results of Geoscience Australia’s 2010 WPA assessment and by updating those findings as far as practicable within the available time of the present Review. Overall, this assessment confirms the results of the 2010 assessment and shows that many parts of the WPA have moderate to high potential for the discovery of new mineral and petroleum resources. Analysis of new data by this 2018 assessment has also identified additional areas with potential for groundwater resources in the WPA. <p>There is high potential for the discovery of new deposits, similar to those already known, especially of copper, gold, silver, iron, titanium and zirconium and uranium. Some of these deposits may contain economic REE and other critical commodities. <p>Modelling of the economic impact of possible new mine developments was carried out for high-value commodities with high potential for discovery in the WPA. The commodities included in the possible future mine scenarios are gold, copper, silver, uranium, iron, titanium and zirconium. Two scenarios were modelled, conservative and optimistic. <p>The Net Present Value of Economic Demonstrated Resources in the WPA is estimated to be $5.9 billion. The Net Present Value of possible future mines in the WPA is estimated to be between $6.4 billion and $19 billion. Annual direct employment across the future possible mines ranges from 150 people to 1350 people per mine, with secondary employment between 70 people and 1250 people. Annual value add across the future possible mines ranges between $8 million per mine to $920 million per mine.

  • The coverage of this dataset is over the WarragambaDam region . The C3 LAS data set contains point data in LAS 1.2 format sourced from a LiDAR ( Light Detection and Ranging ) from an ALS50 ( Airborne Laser Scanner ) sensor . The processed data has been manually edited to achieve LPI classification level 3 whereby the ground class contains minimal non-ground points such as vegetation , water , bridges , temporary features , jetties etc . Purpose: To provide fit-for-purpose elevation data for use in applications related to coastal vulnerability assessment, natural resource management ( especially water and forests) , transportation and urban planning . Additional lineage information: This data has an accuracy of 0.3m ( 95 CI ) vertical and 0.8m ( 95 CI ) horizontal with a minimum point density of one laser pulse per square metre . For more information on the datas accuracy, refer to the lineage provided in the data history . Digital elevation model ( DEM ) were produced using TIN ( Triangular Irregular Network ) method of averaging ground heights to formulate a regular grid for 1, 5 and 10 resolution.

  • Geoscience Australia is the nation’s trusted advisor on the geology and geography of Australia. In its role as the provider of fundamental geographic information for the nation, Geoscience Australia is coordinating new efficient and consistent approaches to cross-government location information supply chains to meet requirements for more detailed and frequently updated national data. This presentation will explore these approaches with a focus on how and why land, property and transport network information can be enabled to ultimately improve outcomes to meet the triple bottom line in the national context - Australia’s environment, its people and economic prosperity. In this presentation, Geoscience Australia will outline how it is collaborating with a wide range of stakeholders in response to increasing demands and expectations for detailed, timely, consistent and interoperable location information throughout Australia. The presentation will describe how existing vehicles for change such as the Foundation Spatial Data Framework, Open Data principles and the Location Index are being used to identify current and future information needs and gaps, examine existing supply chains and identify opportunities to lubricate the flow and integration of vital information underpinning important decisions and policy development.

    The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
