Eric,

I have plenty of trees to shoot right behind my house. Four exceed 130 feet in height and all the large ones exceed 100 feet. Crown shapes vary. I think I'm going to set up an experiment to shoot a dozen or so trees by Michael's method and see how close I can come to the pure sine-based height. I'll track the time it takes me with each method. Should be fun.

As we become more proficient in measuring trees a lot of what goes into the process becomes more and more automatic. After awhile we forget what we had to go through as a learning process that a newby must face with little assurance that things will go right until a lot of experience has been gained.

We should talk about the obstacles to getting it right and always be mindful of the underlying mathematical model. If that can't be explained, there is no assurance that the technique is sound.
