One band case
because shallow bottoms deeper than 3-5 m are assumed to be fairly bright sandy bottoms. This is a reasonable assumption in this highly dynamic environment.

Potential error, alias "uncertainty" can be mapped along with computed depth
Computed depth at Caicos Bank Bahamas Landsat TM image
This is a representation of the degree of uncertainty caused by the 8-bits quantization noise, i.e. by a +/- 0.5 DN uncertainty for all bands used.
