Accuracy & cost

The greater the accuracy, the greater the cost. But how accurate does it need to be? Volume estimates should always be qualified, and even slightly weighted to yield low. This gives a “buffering” capacity, (For instance, by not counting small stems below a defined diameter) but must not be too great or the owner will lose out. It is the assessors responsibility to interpret, and control how contractors will operate.

Be aware that timber can be measured Standing, Felled, Solid volume, Stacked volume, Green weight, Dry weight, Length, Number of pieces, Overbark, Underbark, Top diameter, Taper.
