LiDAR Forest Inventory with Single-Tree, Double-, and Single-Phase Procedures

Table 2

Comparison of single-tree, single-phase, volume predictions from LiDAR data using 0.02 ha circular plots on 10 443 ha of pine plantations with ground plot volume estimates, where sampling error was half the (1−𝛼) confidence interval expressed as a percentage of the mean.
