ABSTRACT:
A timer survey system performing the steps of: placing a first reference point and a second reference point on a tree trunk, wherein an actual distance between the first reference point and the second reference point is a known distance, “A1”; capturing an image of that portion of the tree trunk having the reference points placed on the trunk; measuring on the image an image distance, “D1”, between the first reference point and the second reference point; measuring on the image an image distance, “D2”, between the left outer boundary and the right outer boundary of the tree trunk; and calculating an actual distance, “A2”, between the left outer boundary and the right outer boundary of the tree trunk as follows: A2=[(D2÷D1)(A1)].
