Abstract

An important aspect in designing scanners for earth resources users is the specification of signal to noise and resolution size which is compatible with the cost and space-craft burden that can be supported by the program. There are two areas of conflict between these performance factors. First, either resolution or noise can be improved only at the expense of the other within each cost/ burden ceiling. Second, emphasis on the importance of the two factors differs according to whether the user depends on visual examination of pictures or on automated signature analysis of the multispectral data.
