Abstract

Tests were performed to investigate the geometric characteristics of Landsat 4 images. The first set of tests was designed to determine the extent of image distortion caused by the physical process of writing the Landsat 4 images on film. The second was designed to characterize the geometric accuracies inherent in the digital images themselves. Test materials consisted of film images of test targets generated by the Laser Beam Recorders at Sioux Falls, the Optronics* Photowrite film writer at Goddard Space Flight Center, and digital image files of a strip 600 lines deep across the full width of band 5 of the Washington, D. C. Thematic Mapper scene. The tests were made by least-squares adjustment of an array of measured image points to a corresponding array of control points.
