Cooper GBA region LiDAR

Abstract

LiDAR (Light Detection and Ranging) data was collected for the Geological and Bioregional Assessment Program by Fugro Australia Land Pty Ltd over two mobilisations. The data was acquired at an average density of 1 point per square metre, processed and compiled as LiDAR Classified Data in LAS 1 km tiles and 1 m grid DEM in ESRI ascii 1 km tiles. The total area of survey is 31,780 km². The data was used to develop a Digital Elevation Model and to determine bathymetry for a two-dimensional hydrodynamic flood inundation model of the Cooper Creek floodplain.

History

LiDAR data was acquired by Fugro Australia Land Pty Ltd over two mobilisations. The first mobilisation was flown from 20 March - 4 April 2019 with an aircraft equipped with a Riegl LMS Q780 LiDAR system. The second mobilisation was flown from 6 - 17 October 2019 with an aircraft equipped with a Riegl LMS Q1560 LiDAR system. Nominal flying height was 2800 mAGL with a swath width of 3200 m. Processing steps: • Project Planning • Aircrew briefing • Acquisition as per requirements of dry Season • Field data QA for integrity and completeness • Downloading raw data • QA Raw data • GNSS-IMU Coupled Solution • Riprocess processing • Geodetic Validation Flight Line matching • Ground Filter • LiDAR data Classification • Product Generation LiDAR Derivates • QA of data • Delivery of Data and reports
