Abstract: LANDSAT 4 and 5 Satellite spectral images of the Columbia Basin were obtained during the 1984, 1985 and 1986 growing seasons by Cropix, Inc. of Hermiston, Oregon. A field classification scheme based on the spectral reflectance characteristics of various crops was used to perform a regional crop inventory over an area of more than 50,000 km**2. A personal computer based image processing system was used for the analysis. Accurate information regarding crop acreage and general vegetation condition was compiled and made available to individual growers. Detailed spectral data and vegetation indices for potatoes were calculated and stored for later research on potato yield prediction.
