Description:
Students look at Landsat images of Mt. St. Helens in 1973, 1983, and 1988, and numerically analyze the images several different ways for vegetation and ash cover, using matrices and matrix algebra to extract data. They draw conclusions about the effects of the eruption. They choose and defend a position about which of two or three methods of data extraction and analysis is best.
