Fig. 2From: Assessing forest inventory information obtained from different inventory approaches and remote sensing data sourcesAggregated diameter distributions for all stands based on field measurements (grey bars) and the four inventory approaches (ABA-MV area-based approach, mean values, ABA-DD area-based approach, diameter distribution, ITC individual tree crown, SITC semi-individual tree crown) using ALS as the only remote sensing data source (black line). Note that the y-axis of ABA-MV is different from the others due to the effect of the mean tree on the frequenciesBack to article page
