Abstract

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.
