TERN AusCover routinely collects Terrestrial LiDAR, or Terrestrial Laser Scanning (TLS) at sites around Australia. TLS provides detailed 3D measurements directly related to the quantity and distribution of plant materials above the ground layer, such as canopy height, canopy cover, tree structural information and above ground biomass.


TERN AusCover has regular access to three separate separate TLS systems; Riegl VZ400, Dual Wavelength Echidna Lidar (DWEL) and the Canopy Biomass Lidar (CBL).

  • Riegl VZ400 - Riegl VZ400 is a waveform recording TLS instrument co-owned and operated by the Remote Sensing Centre, Queensland Department of Science, Information Technology, Innovation and the Arts (DSITIA) and the TERN Auscover Brisbane Node, University of Queensland.
  • DWEL - Dual Wavelength Echidna Lidar is a full-waveform recording TLS instrument. Digitizes the fully radiometrically calibrated return waveform of two coaxial lasers, at different wavelengths. Laser wavelengths (1064nm and 1548nm) are chosen to separate green and woody vegetation. DWEL has variable beam divergence (1.25 mrad, 2.5 mrad & 4 mrad. Uses full hemispherical scanning and beyond. Allows measurement of full foliage profiles of the vegetation and vegetation structure, DBH, Height, LAI. This instrument is co-owned and operated the TERN Auscover Canberra Node and CSIRO.
  • CBL - The Compact Biomass Lidar is a lightweight, highly portable TLS system. It has been developed by UMass Boston and due to it's size and portability can be deployed in any terrestrial environment.
