A study was conducted in 1994 in which field data and remotely sensed data were collected from 63 commercial cotton fields in the southern San Joaquin Valley of California. Statistical analysis indicated that relationships could be determined between growth-related crop factors, including canopy light transmittance and ground cover, and quantities evaluated from Landsat satellite imagery. Correlation was also determined between lint yield and the sum of remotely sensed quantities over a portion of the growing season. These findings suggest that regional crop condition and potential yield might be determined from remotely sensed information.
