Notes:
: The trophic characterization of lakes has been intermittently monitored in recent years with data generated from satellite and aircraft spectral scanners. Each of these methods used “ground truth” (lake sampling data) to establish a correlation between scanner-recorded radiance values and a trophic index for each lake (or portion of a lake). The approaches varied in their processing of the digital imagery, as well as in the development of trophic indices. Currently, several states employ varying spectral imagery techniques to develop lake classifications to satisfy the requirements of Section 314 of Federal Water Pollution Control Act. These variations have created a need for developing a uniform, tested approach for use by states and EPA for the description of lake trophic state from multispectral imagery. The current state and the use of multispectral data and technology to determine lake trophic indices is assessed in this paper.
