During fiscal years 1979, Rockwell Hanford Operations sponsored a project at Pacific Northwest Laboratory to perform a land-cover classification of 41,000 mi/sup 2/ of the Columbia Plateau based on digital Landsat multispectral scanner data from 1975. This initial effort set the stage for a follow-on project, initiated in FY 80, which was to perform a similar analysis of the same area using 1979 Landsat data, with emphasis on determining selected land-cover changes between the years 1975 and 1979. Because of the applicability of these selected land-cover data to regional hydrologic modeling, some support for the study was provided by the PNL Assessment of Geologic Isolation System program. Whereas project time and funding elements permitted only a preliminary land-cover classification, efforts to develop and test a computer program for monitoring land-cover dynamics were successful. Accordingly, project results relative to changes in irrigated cropland between 1975 and 1979 are considered to be accurate within 10%. Brief summaries of the work elements accomplished and associated results are presented.
