From: Scheimpflug lidar range profiling of bee activity patterns and spatial distributions
Measured honeybee activity from the lidar is correlated with the observations from the transect walks (a). The correlation is even stronger between the lidar and the hive weights (b). The interpretation could be that the lidar and hive scales measure all flight activity, whereas the Pollard walks only measure bees foraging in part of the field
