Brief description

The Geological and Bioregional Assessment Program collected an extensive LiDAR elevation dataset focused on Cooper Creek Floodplain in Queensland and South Australia. The LiDAR data was collected by Fugro Australia Ltd in two aerial surveys in 2019 covering a total survey area of 31,780 km2 across the Cooper Creek Floodplain, and the Thomson and Barcoo river systems (GBA 2021). 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. As part of the study of the Cenozoic geology, hydrogeology and groundwater systems of Kati Thanda - Lake Eyre Basin for the National Groundwater Systems project (Exploring for the Future program) (see Evans et al. 2024) these 1 km tiles were mosaiced into a seamless grid and resampled to 10 m cell resolution raster images for ease of visualisation and usability across GIS applications (refer to lineage field of this metadata record for the complete reference details of publications cited in this abstract).

Statement:

As part of the study investigating the Cenozoic geology, hydrogeology, and groundwater systems of the Kati Thanda - Lake Eyre Basin the existing 1 km digital elevation model tiles were mosaiced into a seamless raster (GEOTIFF format) and resampled to 10 m cell resolution raster images for ease of visualisation using QGIS open-source software. Hillshade images were derived using ESRI and ERDAS ER Mapper software suites. Relevant external data sources used are: https://elevation.fsdf.org.au; Geological and Bioregional Assessment program at https://data.gov.au/data/dataset/d581de1d-964f-4141-ad9a-eaf500608bb9.

Notes

Purpose
Cooper Creek LiDAR Digital Elevation Model raster layer files were produced for the whole of Cooper Creek Floodplain at 10 m cell resolution with derived multidirectional and traditional hill shaded images, and polygon extent of the LiDAR acquisition area. This dataset is derived from a high-resolution LiDAR survey flown in 2019.
