WebThe geometric principle of measuring tree height is based on the basic principle of similar triangles (intercept theorem). Figure 1 illustrates the geometric principle with the Christen height meter. The device is a simple ruler on which a defined length is marked. A pole is to be put as reference length vertically next to the tree. http://wiki.awf.forst.uni-goettingen.de/wiki/index.php/The_geometric_principle
