Steve: It is suspicious that the measurements of Michigan trees are consistently off by a factor of 0.33 for those trees where we know the true height. A "Thompson Foot" is equal to 9 English inches, so that stated tree heights are about 1.33 times the actual height. However, this result could also come from a piece of equipment that was not calibrated correctly, or from consistent use of the wrong triangulation method. We don't know whether it was intentional or not.
