Digital Landsat data and U-2 aerial photography for the Columbia Plateau region of eastern Washington and Oregon have been combined in order to estimate the total amount of cropland irrigated in this area during 1979 and the amount of growth in irrigated cropland between 1975 and 1979. Four Landsat scenes were required to cover the study area. Each of these scenes were classified scenes were then registered with a stereographic map projection and merged into one file. Irrigated cropland, water, and other land cover classes within this file were edited to conform with U-2 aerial photographs and Landsat color composite prints from 1975 and 1979. Land use data derived from 1975 Landsat imagery (Stephan et al., 1979, Leonhart et al., 1980) were then registered to the same map projection and a map displaying irrigated crop land in 1979 and growth of irrigated cropland between 1975 and 1979 was produced using the discrete table lookup method. The total irrigated cropland for 1979 was found to be 4281 square miles, which represents a 20% increase over 1975. The amount and location of the new irrigated cropland provides essential input into ongoing ground water studies for this region.
