Excerpt
Excerpt: CATEGORIZATION OF NORTHERN GREEN BAY ICE COVER USING LANDSAT. Northern Green Bay ice cover on February 13, 1975, was analyzed using LANDSAT digital data on the computer facilities at the Environmental Research Institute of Michigan. Training sets, consisting of selected areas in the LANDSAT scene that represent various ice types, were entered based upon the tone, texture, and location of the ice within the bay. The classification algorithm used in the analysis consisted of a modified maximum likelihood procedure using the multivariate Gaussian probability density function. It was found that seven ice types could be differentiated in the ice cover, that new (thin) ice could be distinguished from water, and that ice could be distinguished from relatively thin cloud cover. Training set statistics and area tabulations were generated and a color coded categorized image was produced. Recommendations are made for future studies.
