Side by side comparison of Missouri River in 1992 and 1993 (in flood)
The three river scenes shown here are from central Missouri near Gasconade, Rocheport, and the confluence of the Grand River. The first in each pair was in September, 1992, the second in September of 1993. Notice the farmland in the river flood plain. The data uses Landsat TM bands 5, 4, and 2 mapped to red, green, and blue respectively. Bare soil and plowed land appears red, vegetation (which reflects very strongly in the near infrared) appears green, and water is dark blue. The perspective in each of these images is looking approximately westward, which is upstream.
