This paper describes a special character of the multispectral scanner mechanism and can be related to such parameters as sun direction, relative height and scan angle between the dead and shadow angle space by the MSS. This correlation can be easily observed by figure 2-10, 12. Next, it describes a approximate rectifiable theory of the MSS imagery that is based on Konecny's theory. Using this theory, behaviors of the rectifiable elements are investigated; φ, ω, κ, bx, by, bz. The result is applied to determine the overlap quantity by the flight plan and will be suggest to use hardware of a regenerated MSS imagery in the futuer.
