Vertical Crown Dimension Calculation Method: The crown length of a tree is equal to the height from the bottom of the trunk to the crown base minus the total height.
Leaning Tree Height Measurement Method: The height of a leaning tree can be found by multiplying the viewer's distance to the tree by the tangent of the angle between the line of sight and the top of the tree.
