The efficient and effective management of the natural and cultural resources of any country requires accurate and up-to-date information concerning these resources. People involved in the management of agricultural and forest resources at the local level, as well as in various government agencies, often have particularly urgent needs for timely, reliable information concerning the extent, condition, and potential yields of these resources.

Although aerial photography has been in use for many years and for a multitude of purposes, it has only been in the past decade or so that agriculturists and foresters have been seriously researching the potentials of color infrared photography, multispectral optical-mechanical scanners, radar, and other remote sensing instruments and technique. In some cases these instrument systems have been put in to operational use, and in many more situations researchers are thoroughly investigating the capabilities and limitations of the instrument systems and our ability to meaningfully interpret the data obtained from them (4, 5, 7, 10, 11). This next decade will certainly find spacecraft data being effectively utilized for many of the current and untold additional forestry and agricultural applications.
