Remote sensing is the science and art of obtaining information about an object, area, or phenomenon via analysis of data acquired by a device that is not in contact with the target of investigation. ARS is conducting research on remote sensing technologies of benefit to agriculture, forestry, environmental quality and global climate change concerns. The research includes topics of interest to a wide range of managers, from individual producers, agribusinesses, and regional planners to strategic decision makers at the national and international levels. Some examples are presented here.
