In 2013, the MDBA engaged Geoscience Australia to manage acquisition of LiDAR data for a number of areas within the Basin. A major aerial survey is currently taking place across the Murray-Darling Basin, capturing three-dimensional data which will accurately model water flows and enable greater understanding of floodplain inundation. The products will include a 1m bare earth Digital Elevation Model (DEM) and Digital Surface Model (DSM).
