Landsat multispectral scanner (MSS) satellite data was used to identify and analyze temporal change of a wetlands area in the Nebraska Sandhills over an 18 year period. A dual-approach to change detection was utilized: bivariate regression of the spectral data in classification comparison. The former indicates biophysical changes of the land surface, while the latter indicates land cover changes. If both types of changes are found to be significant, then environmental changes of the land surface are revealed. A final analysis involving change images for both spectral and classification data was conducted to gain insight into the nature of the wetlands and the processes at work. It allowed for the examination of spatial variations of change over time.
