In the summer of 1971 the Laboratory for Applications of Remote Sensing at Purdue University conducted a pioneering experiment in the application of remote sensing technology to a large scale earth resource surveillance problem. In 1970 a plant disease called the Southern Corn Leaf Blight infected large areas of corn production in the United States and it is estimated that total national corn production pas reduced by 15% due to this disease. In the winter of 1970, an experiment was designed in cooperation with the U.S. Department of Agriculture, NASA, and the University of Michigan Institute of Science and Technology's Willow Run Laboratories for the summer of 1971 to study the feasibility of detecting and mapping this disease using remote sensing techniques. In this paper, the Corn Blight Watch Experiment will be described from the point of view of data handling, data analysis and interpretation procedures used.
