Abstract : When making geologic interpretations of aerial photography the most significant recognition elements are texture, pattern, association of features, and tone (or color); lesser recognition elements are shape and size. Tone is an important aspect of all the recognition elements, since by tone these other recognition elements are used. The research reported upon here is an evaluation of the concept that tonal differences between formations on aerial photography can be improved through the selection of the appropriate spectral bands.
