Mapping the surface expression and vegetation communities of Australian Great Artesian Basin springs using hyperspectral analyses

This study has provided new information detailing the spatial location, extent and distribution of the surface expression and vegetation communities of the Australian GAB springs at two sites within South Australia. The hyperspectral imagery and analyses employed were capable of detecting and discriminating dominant spring wetland vegetation communities as well as characterizing the surrounding surface expression of the springs (evaporative salt crusts and moist surface seepage zones). The techniques developed in this study will ultimately inform water allocation plan management policies.
