Compute length of a limb or limb segment as the linear distance
from point limb joins trunk to terminal point being measured. 





















































































































































NOTES: 

































1. Limb to be measured is represented by length
L 





























2. Find P_{1} by standing under P_{2,} using clinometer and 












moving and sighting up until a 90 degree
angle is found. 











for the
point P_{2}. P_{1} is underfoot. 































3. H_{1}, H_{2}, D_{1}, and h_{3} and segments
thereofcan all be measured by 











standard ENTS methods/instruments. D1 is
the level distance 











from
tree to line segment P_{1}P_{2.} 






























4. L is computed by the Pathgorean Theorem 













L = SQRT(h_{3}^{2}+D_{1}^{2}).
