Geology of the Wet Tropics Bioregion (WTMA)

Brief description

This dataset contains polygons depicting geology as deliniated by botanist J.P.Stanton and geologist D.J.Stanton within the Wet Tropics bioregion. The geology mapping of the Wet Tropics Bioregion is based on interpretation of aerial photographs during WTMAs Vegetation of the Wet Tropics of Queensland bioregion mapping project. Aerial photography was also used to select sites and traverses for ground truthing work. The geological classification and boundaries were based on their relevence to vegetation patterns. The dataset has been derived from 1:25,000 aerial photography. Botanists J.P.Stanton and geologist D.J.Stanton deliniated vegetation and geology types by manually drawing polygons directly onto the aerial photography. Field verification was also undertaken. Aerial photographs were scanned and authorectified to WTMAs 50k river dataset using an 80m digital elevation model (DEM). Linework was extracted digitally from the rectified photography and attributes added manually. This dataset covers the entire Wet Tropics bioregion. *Positional accuracy* Accuracy is estimated at +/- 12m from true position as depicted on the Australian 1:50,000 Topographic Survey Map Series R733. *Attribute accuracy* Attribute accuracy is estimated at 95%. *Citation* Wet Tropics Management Authority (2013).
