Analysis Ready Data Sensitivity Analyses

CEOS Analysis Ready Data for Land (CARD4L) are satellite data that have been processed to a minimum set of requirements and organized into a form that allows immediate analysis with a minimum of additional user effort and interoperability both through time and with other datasets [1]. In this paper, key input data (e.g. aerosol optical depth, precipitable water, BRDF parameters) needed for atmospheric and BRDF corrections of Landsat data are identified and a sensitivity analysis is conducted using outputs of a physics based atmospheric and BRDF model. The results show that aerosol impacts more on the visible bands where the average variation of reflectance could reach 0.05 of reflectance unit. The variation over dark targets can be much higher so that it is a critical parameter for aquatic applications. By contrast, precipitable water (water vapor in the rest of the paper) only impacts the near-infrared (NIR) and shortwave (SWIR) bands and the extent of change is much smaller. BRDF parameters impact time series most on winter and summer images of highly anisotropic areas and when they are normalized to 45º solar angle. Different BRDF levels for different spectrum ranges not only impact the magnitude of reflectance, but also the signature for these areas. It seems that it is necessary to normalize surface BRDF to ensure time series consistency of the Landsat ARD product.

GSWA P1177 Kukerin pctk 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 potassium grid has a cell size of 0.00083 degrees (approximately 85m) and shows potassium element concentration of the Dumbleyung (SWCC), WA, 2008 in units of percent (or %). The data used to produce this grid was acquired in 2008 by the WA Government, and consisted of 75805 line-kilometres of data at a line spacing between 100m and 400m, and 60m terrain clearance.

Summary Of Data And Results Otway Basin, South Australia Geltwood Beach No. 1 Well Of Beach Petroleum No Liability

Geltwood Beach No. 1 Well was located on the Geltwood Anticline, approximately 7 1/2 miles south-west of Millicent in the Otway Basin, in the south-eastern part of South Australia. The well was drilled by Drilling Contractors (Australia) pty Ltd for Beach Petroleum No Liability, to a total depth of 12,300 feet. Drilling commenced on 22nd August, 1963, and was completed on lOth November, 1963. A full programme of logging, testing, and coring was undertaken.
After passing through 45 feet of Recent calcareous sand, the well penetrated 1860 feet of Miocene to Eocene marine and paralic sediments, and 1760 feet of (?) Palaeocene to Upper Cretaceous sands and grits. Below 3680 feet, a monotonous sequence of Upper to Lower Cretaceous sediments of the Merino Group were encountered and continued to total depth at 12,300 feet.
Geltwood Beach No. 1 Well was drilled to test the hydrocarbon potential of Lower Tertiary and Upper Cretaceous sediments on a probable closed structure in an area where strandings of bitumen and heavy oil on the beaches were thought to indicate SUbmarine seepages. Evidence from wells at Mount Salt and Beachport indicated that Geltwood Beach No. 1 was near the edge of probable wedge-out of Middle to Upper Cretaceous and (?) Palaeocene marine sediments overlying Lower Cretaceous beds. Traces of gas were recorded at intervals from 4500 feet to total depth, but five drillstem tests yielded only slightly gascut salty water and drilling mud. The well was plugged and abandoned as a dry hole.
The stratigraphic drilling operation at Geltwood Beach No. 1 was subsidized under the Petroleum Search Subsidy Act 1959-1961, from surface to total depth.

AUSGeoid98 v.1.0 data files: Moree (sh55-08)

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.

The International Map of the World (IMW) series is no longer maintained, and printed copies of this map are no longer available. The Australian portion of the series consists of 49 maps. They were produced to an international specification using the R502 series at 1:250,000 scale as source material. Production commenced in 1926 and was completed in 1978. The maps were revised from time to time and the last reprint was undertaken in 2003. Each standard map sheet covers 4 degrees of latitude by 6 degrees of longitude and was produced using a Lambert Conformal Conic projection with 2 standard parallels. The series has recently been superseded by the 1:1 000 000 topographic map general reference.

Radiometric Grid of Australia (Radmap) v4 2019 unfiltered pct potassium

The unfiltered potassium grid is a derivative of the 2019 radiometric grid of Australia. 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 2019 unfiltered potassium grid has a cell size of about 100 m (0.001 degrees) and shows potassium element concentrations of the Australia region. Potassium is the seventh most abundant element in the Earth's crust. The potassium concentration grid can be used to locate minerals and compounds containing potassium.

A crustal profile across the Archaean Pilbara and northern Yilgarn cratons, northwest Australia

Two Archaean cratons are exposed in the Precambrian shield of Western Australia: the Pilbara in the north and the Yilgarn in the south. They are separated by the Capricorn Orogen. Seismic recordings of quarry blasts in the north of the West Australian shield indicate that the upper crustal rocks have seismic velocities of 6.0 km s^-1, and are probably of acid to intermediate chemical composition. They overlie a lower crust, presumed to be granulitic, which has a seismic velocity of 6.4 km s^-1 at 13 km depth in the north of the Pilbara Craton and 16 km in the north of the Yilgarn Craton. The northern Yilgarn has a third layer, with a seismic velocity of about 7.0 km s^-1, at the base of the crust. This may represent a higher grade (eclogite?) phase, or it may indicate injection of basic material into the base of the crust. The crust-mantle boundary at the base of the Pilbara Craton and Capricorn Orogen appears to be transitional - it shows velocity gradients rather than a first-order velocity discontinuity. Within the Pilbara Craton, the crust is about 28 km thick in the north and 33 km in the south. South of the Pilbara Craton, the crust thickens under the Capricorn Orogenic Belt, and again under the northern Yilgarn Craton where it is 52 km thick. The form of the structures in the zone of thickening cannot be determined uniquely from the present data. Three models incorporating faults or monoclines and a wedge of 7.0 km s^-1 material at the base of the crust have been derived. The different crustal thicknesses of the cratons suggest that they formed separately and were then tilted towards the Orogenic Belt.
