Tree structural characteristics are collected at the centre of a site, usually in conjunction with the Statewide Landcover and Trees Study (SLATS) star transect field data. The basal wedge is first used to identify a sample of trees then direct measurements are taken of each tree, which constitute the tree structural characteristics.Tree structural measurements have been collected at several locations across Australia (including the formally known AusCover Supersites) to relate field-based measurements to satellite data products, such as Landsat-derived ground cover estimates. Data can be downloaded from https://field.jrsrp.com/ by selecting the combination Field and Tree Structure.

Purpose
Field data on tree structural characteristics can be used for the calibration and validation of LiDAR derived products of tree height, canopy height profiles and allometrically derived Diameter Breast Height (DBH).
