The Sine Method as An Alternative Height Measurement Technique

Inside the research note we can get description about trees, method, forestry, highest, height, journal, hypsometers, tangent method, forest, grown trees, highest apparent point, length, sine method, and crown. There are lots of information such as height measurement techniques, growth, remote sensing, sine, tree height, baseline length, laser rangefinders, tangent methods, technology, baseline distance, distance, tree measuring, and point are explained in the research note.

The research note contains info such as observer, sensing, slope, heights, remote sensing environment, measurement, mean standard deviation, offset errors, tangent, laser, electronic hypsometers, triangle, and highest point. Here are excerpted from this research note:

A new approach, the sine method, can improve height measurement by being less sensitive to the requirements of conventional techniques (similar triangles and the tangent method). We studied the sine method through a couple of comparisons. First, we demonstrated the validity of the sine method under idealized conditions by comparing tangent and sine measurements on a stationary object of a known height. Then, we compared heights collected via climbing and lowering a tape from the highest point of a number of forest-grown trees with heights measured with the sine method. The sine method offers a viable, cost effective alternative to traditional measurement approaches, especially for large or leaning trees, and for trees with broadly spreading crowns.

Additionally, the research note gives us discussion about measurement technique, techniques, conventional height measurement, measurements, tower, horizontal planes, methods, research, standard deviation, base, accuracy, total height, and height measurement.
