The spatial complexity of Kunoth Paddock means that it was very difficult to verify the
results of hyperspectral remote sensing analyses using just conventional
ground-based measurement. Consequently, we acquired aerial video imagery on a number of
transects in May 2001.
The imaging equipment used was a Specterra Systems Digital Multi-Spectral Video System
(DMSV) based on a 2 x 2 array
of Cohu 4910 CCD cameras producing CCIR output. Details of the system are given in Pickup
et al, (1995a).
Multi-spectral capacity is provided by four 25 nm bandwidth interference filters centred
on 450 nm, 550 nm, 650 nm and
770 nm allowing data collection in the blue, green, red and near-infrared regions. Frame
positions are estimated using data
from a global positioning system which is interrogated at one second intervals.
Aerial Video Imagery for the transects listed in the table below were acquired with the
CAZR DMSV aerial video system in Kunoth Paddock on May 9, 2001.
Examples of the aerial video imagery:
1 metre resolution mosaiced transect: mosaich1a
20cm frames ch20a10, ch20a11, ch20a12, ch20a13
50cm resolution frame
2 metre resolution frame
