THE EVALUATION OF MULTISPECTRAL IMAGERY FOR A TIDAL MARSH ENVIRONMENT.
Abstract
A variety of multispectral imagery, including nine-lens multiband imagery in the 400-900 millimicron range, panchromatic, Ektachrome, and Ektachrome-Infrared photography, has been obtained for a tidelands area in San Francisco Bay. A technique for comparing their relative utility for specific geomorphic interpretations has been developed, whereby a subjective form of tracing analysis may be correlated with a more objective (and quantitative) scheme of selected microdensitometer traverses across the various negatives and positive transparencies. The results suggest that the nine-lens multiband imagery is excessive, and, that for a similar use as that of the photos studied, could be reduced to four-lens imagery. The most useful frames are the 550-630 millimicron bandwidth, the near-infrared, the Ektachrome color transparency, and the Ektachrome-Infrared transparency. (Author)
