Satellite-based multispectral imaging systems have been in operation since 1972 and the latest in the Landsat series of sensors was launched in July 1982. One system parameter of interest is resolution and this paper discusses experiments to determine the actual overall resolution after launch. Atmospheric effects and postprocessing effects add to the prelaunch optical resolution. Scene structures, such as roads and field edges, were used with numerical estimation procedures to predict resolution in Landsat-4 Thematic Mapper imagery. A nominal resolution of 39 meters was determined as compared to the predicted 30 m prelaunch value.
