Using cutting edge technology to monitor habitat condition in the Northern Territory's Beetaloo Sub-basin

CSIRO researchers have used drones (UAVs) fitted with LiDAR sensors and satellite-based remote sensing platforms to map a key area of vegetation in the Beetaloo Sub-basin.

This project explored the development of a scalable and systematic approach for monitoring the structural condition of vegetation in the Beetaloo region.

LiDAR (Light Detection and Ranging) is a remote sensing method that uses laser pulses to measure distances. When mounted on drones, LiDAR sensors can produce detailed three-dimensional maps of vegetation and terrain.

Scientists successfully demonstrated the application of high‑resolution UAV-LiDAR (sensor-equipped drones) to characterise a study site in the Beetaloo.

UAV-LiDAR data was used to calibrate spaceborne remote sensing data for site survey and habitat condition monitoring
in the Beetaloo. Researchers processed multiple years of Sentinel-1 Synthetic Aperture Radar (SAR) satellite imagery creating monthly, seasonal and annual composites.

Project results confirm the potential for upscaling and developing a systematic, cost-effective habitat monitoring program.
