The digital terrain model is calculated by subtracting the terrain clearance
(radar altimeter) from the differentially corrected GPS height,
The GPS height had the ellipsoid/geoid separation “N” values applied to it
real time and is relative to the geoid and as such the resulting calculated
digital terrain height is above the Australian Height Datum or AHD.

Aircraft Magnetic Compensation
At the start of the survey the systems were calibrated for reduction of
magnetic heading error. The heading and manoeuvre effects of the aircraft
on the magnetic data were removed using an Data Acquisition & Adaptive
Aeromagnetic Real-Time Compensator (DAARC500).
Calibration of the aircraft heading effects were measured by flying a series
of pitch, roll and yaw manoeuvres at high altitude while monitoring changes
in the three axis magnetometer and the effect on total field readings. A 26
term polynomial model of the aircraft magnetic noise covering permanent,
induced and eddy current fields was determined. These coefficients were
then applied to the data collected during the survey in real-time. The
coefficients are listed in Appendix F.
The compensation flight data was recorded and then checked to ensure the
acquisition of the compensation solution was without spikes or dropouts. A
testbox flight was then recorded repeating the series of pitch, roll and yaw
manoeuvre on all cardinal headings as with the compensation flight but now
using the approved solution stored in the DAARC500. This testbox flight
data was then processed to test the validity of the compensation for all
cardinal headings, north, south, east and west.

DATA PROCESSING PROCEDURES
7.1
Data Pre-processing
The raw binary survey data was downloaded from the aircraft after each
flight and transferred to the field computer. Using UTS Geophysics
developed software the flightpath was first reviewed to confirm line
navigation and terrain clearance specifications had been met and the data
was trimmed to the correct survey boundary extents, adjustments were then
made to the data positions with respect to time to remove fixed system
parallax or lag offsets, the magnetic and radar altimeter data was adjusted
by -0.300 seconds, and the radiometric data by -1.400 seconds for each
flight.
The trimmed and parallax corrected data was then exported as located
ASCII data and loaded into field data bases for further quality control
procedures which include visual scrutinisation of channel profiles and grids.

Logistics Report
Magnetic Data Processing
The diurnal data were filtered with a 13 point moving average filter to
reduce noise levels, followed by second difference filter to identify and
remove spikes of less than 0.25 nT.
The filtered diurnal measurements were subtracted from the diurnal base
field and the residual corrections applied to the survey data by
synchronising the diurnal data time and the aircraft survey time. The
average diurnal base station value was added to the survey data.
An eighth difference filter was run on the raw magnetic survey data in order
to identify any remaining spikes in the data, which were manually edited
from the data.
The X and Y positioning of the data was then checked for spikes before
applying the IGRF correction. Any spikes in the positions were manually
edited. The updated IGRF 2010 correction was calculated at each data
point (taking into account the height above sea level).
This regional magnetic gradient was subtracted from the survey data points.
An assessment of the data at this point showed that no major levelling
problems existed in the residual magnetic data.
Survey tie line leveling was then applied to improve the DC component of
the magnetic data. A single micro-levelling pass was then applied to the
data to correct any minor level errors due to variations in terrain clearance
or other factors. The micro-levelling process targets wavelengths of 2 x line
spacing interval (in this case, 800m) using a proprietary method.
For a given target wavelength a reference grid was constructed and then
filtered by two dimensional operators. A file of levelling corrections is
generated from comparing the survey line data and the reference grid for
each target wavelength and then subjected to statistical analysis. Limits are
established for the levelling corrections based on these statistics, and the
levelling corrections restricted to these limits. The microlevelling corrections
are then applied to the survey line data and the resulting line data are
interrogated. Limits of +/- 6 nT were used for the levelling corrections.
Located and gridded data were generated from the final processed
magnetic data.

Logistics Report
Radiometric Data Processing
Statistical noise reduction of the 256 channel data was performed for each
aircraft using the Noise Adjusted Singular Variable Decomposition (NASVD)
method described by Hovgaard and Grasty (1997).
A noise-adjusted singular value decomposition is performed, and the
number of components to be used is determined by inspection of plots of
the spectral components and by a statistical analysis of the contributions of
the components. If the spectral shapes show any unusual characteristics,
further analysis of the concentrations of the spectral components in the line
data is performed in order to identify and eliminate any corrupt spectra. If
such spectra were eliminated, the NASVD process is re-performed, in order
to obtain spectral components free of any bias from corrupt spectra.
Only the dominant spectral shapes (identified as described above) were
used in the spectral reconstruction process.
The first 8 NASVD
components were used for this process.
Channels 30-250 only are spectrally smoothed, as these contain the
regions of interest and are not dominated by the lower end of the Compton
continuum. The energy spectrum between the potassium and thorium
peaks was recalibrated from the spectrally smoothed 256 channel
measurements.
The aircraft background spectrum and the scaled unit cosmic spectrum
were then subtracted from the 256 channel data. This 256 channel data
were then windowed to the 5 primary channels of total count, potassium,
uranium, thorium and low-energy uranium. Dead time corrections were then
applied to the data. Radon background removal was performed using the
Minty Spectral Ratio method (1992).
The radar altimeter data was first clipped to give a maximum height of 300m
to prevent errors being introduced where the aircraft was required by law to
be above this height, the clipped radalt data was then corrected to a
standard temperature and pressure, and height corrected spectral stripping
was applied to the windowed data. Height attenuation corrections based on
the STP radar altimeter were then performed to remove any altitude
variation effects from the data.
The Uranium and Total Count channels were tie-levelled to remove the
effects of residual radon background. The tie-levelling process employed
was a least-squares/median filter procedure, which generated a single
correction for each line of data. Mis-matches were calculated at each tietraverse intersection and the median mismatch for each flight line was
calculated as the residual levelling error for that line.
Page 17
UTS Geophysics
Logistics Report
Final micro-levelling techniques were then selectively applied to the tie line
levelled data to remove minor residual variations in profile intensities, as per
the method outlined for magnetic data micro-levelling in 7.2 above.
Limits of +/- 50 cps for Total Count, +/- 5 cps for Potassium, +/- 5 cps for
Thorium and +/- 5 cps for Uranium were used for the levelling corrections.
The corrected count rate data was then converted to ground concentrations
for potassium, uranium and thorium (sensitivity coefficients are supplied in
Appendix F).
Located and gridded data were generated from the final processed
radiometric data.

Digital Elevation Model Data Processing
The raw radar altimeter and GPS altitude data was checked for spikes and
steps, and any found were manually edited.
The radar altimeter height plus the vertical separation distance between the
GPS and radar altimeter antennae (1.4 metres) was then subtracted from
the GPS altitude to calculate the digital terrain height.
The digital terrain data thus derived was tie line levelled and gridded. The
tie-levelling process employed was a least-squares/median filter procedure,
which generated a single correction for each line of data. Mis-matches were
calculated at each tie-traverse intersection and the median mismatch for
each flight line was calculated as the residual levelling error for that line.
The tie-levelled data were then examined and subjected to a 2-pass
microlevelling procedure targeting wavelengths of 800m and 400m, with
correction limits of 5.0m and 2.0m respectively, to produce the final digital
terrain model data channel. The final digital terrain model grid displayed no
line dependent artifacts.
This elevation model was compared with existing digital elevation data
downloaded from the Geoscience Australia website.
The following table contains spot height checks between the final processed
digital elevation data and the Aust bathymetry and topography 250m 2006
