It has been suggested that bathymetry measurements from multispectral
digital imagery could be improved by basing the selection of bands to be used
in the calculation on the water depth. Only the deepest penetrating bands
should be used in the deep-water regions; only the longer wavelength, less
penetrating bands should be used in the shallow-water regions. We have used
Thematic Mapper bands one through four to test this new approach in an image
of Key West, Florida. The results show no improvement over the standard
algorithms. The method of band selection is described and bathymetric results
are presented, including a comparison with the usual method of using all
water-penetrating bands at once.
