Abstract
The Macquarie Barwon LiDAR survey provides elevation and photographic data over approximately 17,326 km² along the Macquarie and Barwon Rivers, north-west of Dubbo NSW. The LiDAR was captured between November 2013 and May 2014, at a nominal density of two outgoing laser pulses per square metre. Photography was captured simultaneously and provided as an ortho-rectified mosaic with a resolution of 20cm. The LiDAR was delivered in a full waveform format that retains a higher level of precision and significantly more above ground information than traditional LiDAR. A set of seamless products, including hydro-flattened bare earth terrain surfaces (DEMs), were produced to the ICSM specification. Other derived surfaces include a Digital Surface Model (DSM), Canopy Height Model (CHM) and Foliage Canopy Model (FCM). The outputs of the project are compliant with National ICSM LiDAR Product Specifications and the NEDF.
