Anybody know a sure way to view a standing tree and calculate it's exacty height?
You need a Biltmore stick. Its used to measure board feet of standing trees. No math, no measuring shadows, none of that. Just stand 66 feet from the base of the tree, hold the stick 23 inches from your eye and add up the tree height. A Biltmore stick starts measuring above the stump, thats where useable logs start, then it divides the tree into 16 foot logs. When you use it for measuring overall height, put the first mark at ground level, count full logs of 16 feet, when you get to the top of the tree you will have a partial log. If the partial is half of the log section its 8 feet, if its roughly a quarter of the log section, its 4 feet. Add up the full log sections and the partial at the top and thats total tree height. It takes longer to read what I just typed up than to use it.
Just google "Biltmore Stick" and you will find a ton of articles on them and several on how to make one since they cost about $50 to buy when they are just different marked yard sticks.
