Brief description
Ground lidar, also known as Terrestrial Laser Scanning (TLS), is a ranging instrument that provides detailed 3D measurements directly related to the quantity and distribution of plant materials in the canopy. This dataset contains raw instrument data and ancillary data for numerous sites across northern and eastern Australia from 2012 onwards. Scans have been collected using two Riegl VZ400 waveform recording TLS instruments. One is co-owned and operated by the Remote Sensing Centre, Queensland Department of Environment and Science (DES) and the TERN Auscover Brisbane Node, University of Queensland. The second is owned and operated by Wageningen University, Netherlands.
Data can be accessed from https://field.jrsrp.com/ by selecting the combinations Field, Ground Lidar. Raw data are accessible by selecting individual locations on the map and then clicking on the TLS scan directory link on the right hand site of the screen.

Lineage
Data Creation
Processing:
An automated TLS processing system has been developed by the Remote Sensing Centre, Queensland Department of Environment and Science (DES) using the Riegl RiVLib and RiWaveLib C++ libraries and the Sorted Pulse Data Library (SPDLib; Bunting et al., 2013a). Data is made available in published open standards including compress LAS format (LAZ; ASPRS, 2010) and the HDF-5 Sorted Pulse Data format (SPD; Bunting et al., 2013b).
Sampling Protocol:

Notes
CreditWe at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging.
The following organisations contributed to the data collection: Joint Remote Sensing Research Program, University of Wageningen, University of Adelaide (Ausplots) and CSIRO.
This work was funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project.

TLS measurements can be used for applications requiring quantification of vegetation structure parameters, tree and stand reconstruction, and terrain analysis.
