Otway Basin magnetic grid geodetic

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.
This Otway Basin magnetic grid geodetic has a cell size of 0.001 degrees (approximately 99m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1994 by the SA, VIC Government, and consisted of 44345 line-kilometres of data at 500m line spacing and 130m terrain clearance.

GSNSW Exploration NSW Area S Braidwood thorium grid geodetic

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.
This radiometric thorium grid has a cell size of 0.00049 degrees (approximately 50m) and shows thorium element concentration of the NSW DMR, Discovery 2000, Area S, Braidwood, NSW 2001 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 25736 line-kilometres of data at 250m line spacing and 60m terrain clearance.

AUSGeoid98 v.1.0 data files:  (sc48-12)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Potash in Australian Acid Salt Lakes

Potash is the common name for various salts that contain potassium (K) in water-soluble form and is an important component of many fertilisers. Because of its importance, a review was carried out into  the potential of Australian salt lake systems from arid areas for potash, lithium, boron, and calcrete-hosted uranium deposits (Mernagh et al., 2013). Following this study, Geoscience Australia investigated the depositional environments, studied various examples and considered exploration histories of Australian acid salt lakes.

Newdegate 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

Central Gawler Gold Data Catalogue

This data catalogue was compiled for use by memebers of the Central Gawler Gold Sub-project.  The compilation forms the basis of a continuing data location and stocktaking exercise.
This data catalogue consists of data collected from known digital records at PIRSA and GA for the Central Gawler Gold region in Central South Australia. 
Much of the data was sourced from PIRSA's South Australia DVD dataset with additional information from PIRSA and GA's coporate databases and PIRSA's open file records. Information on non-digital data was assembled from PIRSA's pre 1997 open file records and through communications with the various researchers who have work in the region.

OCCAM 5.0 Very Long Baseline Interferometry (VLBI) analysis software - users guide

OCCAM 5.0 has new limits: 20 stations and 100 radiosources can be processed simultaneously. The number of baselines under study is 190, correspondingly. The current version of OCCAM supports IERS Conventions 2000. The ephemeride DE405/LE405 takes the place of DE403/LE403. To correct subdiurnal EOP variations two models can be chosen: proposed by Ray (recommended by IERS Conventions 1996) and by Eanes (IERS Conventions 2000) which takes into account many more tidal terms. A new leastsquares approach based on the Gauss-Markov model is available with the new version

Digital Earth Australia Intertidal

Intertidal environments contain many important ecological habitats such as sandy beaches, tidal flats, rocky shores, and reefs. These environments also provide many valuable benefits such as storm surge protection, carbon storage, and natural resources.&nbsp;
&nbsp;
Intertidal zones are being increasingly faced with threats including coastal erosion, land reclamation (e.g. port construction), and sea level rise. These regions are often highly dynamic, and accurate, up-to-date elevation data describing the changing topography and extent of these environments is needed. However, this data is expensive and challenging to map across the entire intertidal zone of a continent the size of Australia. &nbsp;
&nbsp;
The intertidal zone also forms a critical habitat and foraging ground for migratory shore birds and other species. An improved characterisation of the exposure patterns of these dynamic environments is important to support conservation efforts and to gain a better understanding of migratory species pathways. &nbsp;
&nbsp;
The DEA Intertidal product suite (https://knowledge.dea.ga.gov.au/data/product/dea-intertidal) provides annual continental -scale elevation and exposure products for Australia’s intertidal zone, mapped at a 10m resolution, from Digital Earth Australia’s archive of open-source Landsat and Sentinel-2 satellite data. These intertidal products enable users to better monitor and understand some of the most dynamic regions of Australia’s coastlines.

Applications

   - Integration with existing topographic and bathymetric data to seamlessly map the elevation of the coastal zone.&nbsp;
&nbsp;
    - Providing baseline elevation data for predicting the impact of coastal hazards such as storm surges, tsunami inundation, or future sea-level rise.&nbsp;
&nbsp;
    - Investigating coastal erosion and sediment transport processes.&nbsp;
&nbsp;
   - Supporting habitat mapping and modelling for coastal ecosystems extending across the terrestrial to marine boundary.&nbsp;
&nbsp;
    - Characterisation of the spatio-temporal exposure patterns of the intertidal zone to support migratory species studies and applications.&nbsp;
