As part of the Urban Digital Elevation Modelling (UDEM) Project (July 2008- June 2010), Airborne LiDAR data were acquired in partnership with State jurisdictions over priority areas including Perth-Bunbury, Adelaide, Brisbane and the Gold Coast, Melbourne, Sydney and the NSW Hunter and Central Coast. These datasets were then further processed to produce hydrologically enforced and conditioned DEMs (Hydro-DEMs).
