Muttaburra 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Eucla Southwest Gravity Complete Spherical Cap Bouguer 1VD Geodetic

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Eucla Southwest Gravity Complete Spherical Cap Bouguer 1VD Geodetic is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the Eucla South West Gravity Survey (P201162). This gravity survey was acquired under the project No. 201162 for the geological survey of WA. The grid has a cell size of 0.005 degrees (approximately 513m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  A total of 3800 gravity stations at 2500m spacing were acquired to produce this grid.

Radiometric Grid of Australia (Radmap) v4 2019 filtered terrestrial dose rate

The filtered terrestrial dose rate grid is a derivative of the 2019 radiometric or gamma-ray grid of Australia, made of a combination of over 600 individual survey grids. 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 are collected on airborne geophysical surveys conducted by Commonwealth, State and Northern Territory Governments and the private sector.
The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to the unfiltered grid to generate the filtered terrestrial dose rate grid. The grid cell size is about 100m (0.001 degrees).

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC2km4kmRes)

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 2019 Total magnetic Intensity (TMI) grid of Australia has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the sixth edition was released in 2015, data from 234 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. The new grid was derived from a re-levelling of the national magnetic grid database. The survey grids were levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS), which serves as a baseline to constrain long wavelengths in the final grid. It is estimated that 33 500 000 line-kilometres of survey data were acquired to produce the 2019 grid data, about 2 000 000 line-kilometres more than for the previous edition. 
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 Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC2km4kmRes) is a pseudocolour image of the TMI grid of the Magnetic Anomaly Map of Australia, Seventh Edition, 2019.
This grid has a cell size of 0.00083 degrees (approximately 88m). This pseudocolour image shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The image can also be used to locate structural features such as dykes.

Geology of the Ayr

These data are a digital representation of information depicted on the printed map of the Ayr 1:250 000 Geological Series produced by AGSO and the Geological Survey of Queensland (GSQ) in 1968.
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

AUSGeoid98 v.1.0 data files:  (sj50-07)

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.

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.

Mk II Airborne Laser Fluorosensor Survey Reprocessing and Interpretation Report: Great Australian Bight, Southern Australia

The Great Australian Bight airborne laser fluorosensor (ALF) MkII survey was flown in 1989 by BP. The MkII system used a 308nm laser wavelength, longer than the 266nm used in the later MkIII system. The Raman peak wavelength is 344nm and the fluorescence region is 370nm to 580nm.
This report is a reinterpretation of the original BP data using ALF_Explorer software. Survey lines were numbered from 1 to 281 but many lines had several segments. A total of 520 line segments were detected in this survey using a line break distance of 100m. Lines 201 and 203 had 92 and 71 segments respectively. A noisy navigation system may have produced apparent breaks on these lines. If the extra segments on these lines are excluded, the survey contains 359 segments. 
The lines were acquired at approximately 3,000m spacing in a NS orientation and a flying height of 100m. A total of 33,154,869 spectra were processed at an average spacing of 15m to 22m. Each recorded spectrum is the average of ten detected spectra. The averaging was done to reduce the data recording rate, which was limited by the available hardware.
The fluorescence response was very weak for the Great Australian Bight ALF survey, requiring a very sensitive detection method. The 3km line spacing is not sufficiently close to detect most fluor clusters. The Great Australian Bight ALF MkII data is probably not suitable for identifying the isolated, low intensity fluors.
