Fig. 2From: The utility of terrestrial photogrammetry for assessment of tree volume and taper in boreal mixedwood forestsA representation of the two different curve matching techniques (not weighted and weighted) used in this study. w in the equations indicates the weight applied to the residual closest to 3.28 m. In this simplified example, the blue and yellow lines represent two candidate curves coming from the generated taper curve database. In the curve database, however, there were approximately 90,000 candidate curves for each species in each ecoregionBack to article page
