The procedures used in developing the photointerpretation key are presented in part 1, and the resulting selective photointerpretation key with color illustrations (stereopairs) is presented in part 2. This photointerpretation key represents a model application of high-altitude color infrared panoramic photography to timber inventory and should pave the way for more imaginative applications of optical bar technology to resource inventories. 收起
