Table 1. The retrieved R2 by applying a linear and logarithmic regression between biomass and vegetation volume. The reported values are the significant ones according to the f2 test for the sample size. The minimum threshold for power is 90% here. AG and PG here means annual and perennial grass, respectively. Plot volume is the voxelized volume of the total plot without classification, and vegetation volume is also voxelized volume but after classification per the workflow (Fig. 3).
