Canopy mapping surveys the position and size of all of the limbs down to a certain size in the crown of the tree and is commonly used when measuring the overall wood volume of a tree. Average crown spread is one of the parameters commonly measured as part of various champion tree programs and documentation efforts.
You can do this by moving toward or away from the tree, adjusting the stick length, and by moving your arm up and down; 2) once aligned, measure the distance from the top of your hand grasping the base of the stick to your eye; 3) measure the distance from the top of your hand to the top of the stick; 4) measure the distance from your eye to ...
The length and diameter measurements of the limbs can be accomplished by climbers physically measuring these values, or through remote methods, or a combination of both. In most cases the branch diameters are only measured down to a certain lower size limit, and the volume of the remaining finer branches is ignored, or extrapolated. [citation ...
In between the posts, two 2x4s are attached to the posts with screws for the best connection. The lower board is placed 3.5" from the top of the finish deck to the bottom of the board. The top board is placed with the top at 35" from the deck. Then the vertical 2x2 pressure treated wood balusters are installed spaced regularly every 3.5". Then ...
Measuring on the upslope side if often easier, it is also higher on the tree and likely will include less of the flare at the base of the trunk, and when measuring extremely large trunk on a slope the upslope side of the girth loop will always be above ground level. Measuring the girth from a reference point at midslope also has advantages.

Crown spread is a measure of the footprint or plan area of the crown of the tree expressed as a diameter. [2] The most basic crown spread measurement is the average length of two lines across the crown area. The first measurement is made along the longest axis of the crown from one edge to the opposite edge.
