Terrestrial laser scans - Riegl VZ400, individual tree point clouds and cylinder models, Rushworth Forest
Terrestrial laser scans were acquired in native Eucalypt Open Forest (dry sclerophyll Box-Ironbark forest) in Victoria, Australia. Two plots (RUSH06 and RUSH07) with a 40 m radius were established in Rushworth forest and partially harvested in May 2012 to acquire accurate estimates of above-ground biomass. The main tree species in these plots were Eucalyptus leucoxylon, Eucalyptus microcarpa and Eucalyptus tricarpa. Single trees were extracted from the TLS data and quantitative structure models were used to estimate the tree volume directly from the point cloud data. Above-ground biomass (AGB) was inferred from the derived volumes and basic wood density information, and compared with estimates of above-ground biomass derived from allometric equations and destructive sampling.

- The quality of point clouds and derived cylinder model are dependent on registration accuracy. Reflecting targets were distributed throughout the plot and were used to register the scan locations using the Riegl RiSCAN PRO software. The average standard deviation of the registered point clouds was 0.0129 m with values for individual scans ranging from 0.0062 m to 0.0226 m.
Report
Result
- Statement
- AGB estimates derived from TLS show a high agreement with the reference values from destructive sampling, with a concordance correlation coefficient (CCC) of 0.98. The agreement between AGB estimates from allometric equations and the reference is lower (CCC = 0.68 to 0.78). The TLS approach shows a total AGB overestimation of 9.68% compared to an underestimation of 36.57% to 29.85% for the allometric equations.
Resource lineage
- Statement
- Data was collected at five sampling points in a plot using a cross sampling protocol. To operate the scanner must necessarily be placed in a gap, so any deviations from the nominal sampling location illustration below are outlined in the associated shapefile/KMZ file for this data set.
