Abstract
A measuring device measures the width of trees and other vertically disposed objects at a distance from these objects. An aiming instrument cites various points along the object and measures a distance to the object as well as provides a signal proportional to a plumb line angle sensor, a signal proportional to a horizontal angle device, and a distance measuring signal. A computer coupled to the aiming instrument will compute the diameter of the trees or other vertically disposed objects from the distance signal, angle sensor signal and horizontal angle device.
