This dataset contains LiDAR data collected at TERN’s Calperum Mallee SuperSite during a field trial of an Uncrewed Aircraft System (UAS), undertaken to evaluate the use of drone-based LiDAR for the TERN Drone project across current and future TERN sites (AusPlots, SuperSites, and Cal/Val sites). Standardised TERN Ecosystem Surveillance Drone Data Collection and Data Processing protocols are used to collect drone imagery and to generate orthomosaics. The aim of drone surveys is to capture the vegetation structure. The standardised data collection and data processing protocols developed in 2022 are based on the DJI Matrice 300 (M300) RTK drone platform. Lidar sensor DJI Zenmuse L1 is used with DJI Matrice 300 (M300) RTK platform to capture RGB colourised 3D point clouds. The data is georeferenced using the onboard GNSS in M300 and the D-RTK 2 base station. DJI Terra software was used to generate 3D point clouds from the raw lidar data. The protocols include flight planning and data collection guidelines for a 100 x 100 m TERN plot, and the processing workflow used on DJI Terra. Mission-specific metadata for each plot is provided in the imagery/metadata folder (please refer to the imagery collection).

Purpose
The aim of the drone-based lidar surveys is to achieve consistent and robust data collection of vegetation structure to facilitate ecosystem monitoring. Vegetation structure is an important indicator of aboveground biomass and carbon storage. Drone lidar captures detailed information on the three-dimensional structure of vegetation and landscape. Critical characteristics that can be measured through this data include crown projection area, crown diameter, tree height. Lidar data can be used to generate precise digital elevation model under the forest canopy, track changes in erosion and deposition of soil, assess aboveground biomass, and fuel loads in terrestrial ecosystems.

TERN’s Calperum Mallee SuperSite is in a mallee semi-arid ecosystem, fringing the River Murray floodplains on Calperum Station, near Renmark, South Australia. The area comprises undulating mallee woodlands and riverine vegetation alongside the river. All areas are in the process of recovering from extensive grazing. The Native Title for the area is held by the First Peoples of the River Murray and Mallee.
