This image shows the Thomson River, near Longreach in Central Queensland. The water in the river channels appears blue, while the fringing riparian vegetation appears dark green. Dry channels and the floodplain are pale blue or white, reflecting their bare surface. The surrounding landscape is dominated by plains of Mitchell grass, which appears as various shades of purple, depending on the proportion of bare ground and dry ground cover. The Remote Sensing Centre measures and monitors ground cover across Queensland to support sustainable land management.
This aspect of the plinth shows a strong declining trend in green ground cover, visible in the centre of the piece.
This image shows the Georgina River, west of Boulia in Queensland’s Channel Country. Floodwaters fill some of the many braided river channels, while the surrounding arid landscape appears in various shades of orange. The Remote Sensing Centre conducts fieldwork even in this remote part of Queensland, to calibrate the satellite imagery with conditions across the state.
Most of the interesting data trends appear in the first months of the year on this aspect of the plinth.
This image shows the North Kennedy River and Princess Charlotte Bay, on Cape York in North-Eastern Queensland. The sinuous loops of the river wind through woodlands and grasslands, before reaching the mangroves and salt flats of the coast. In the southern part of the image, a dark area shows a recent fire scar. The Remote Sensing Centre has used satellite imagery to map fire scars across Queensland since 1986.
The cadence of the seasons is much more rhythmic and regular on this side of the piece, with the regular wet and dry seasons quite evident.
