Owen,

Thanks for the additional photos, very impressive!

I don't have a Nikon 550, but I've read that it has both the 3 point routine (tangent) and 2 point routine (sine). Do you use the more accurate 2 point routine?

Matt

Hi Matt,
yes I make sure to use the 2 point sine method. Some time back, I had a quick e-discussion with Ed to make sure I was following NTS protocols for heights. I measure each tree I report a height for at least 2-3 times to make sure the height is reproducible. As a general approach, I try to report a conservative "lower-bound" height: i.e. the tree is at least as tall as the height quoted, many of them could be taller by a foot or two.
Best,
Owen
