3. Arrange the two windows on the screen so that you can examine them
together, expanding and zooming in as needed to be able to view the
stadium in all three band combinations.
Question 11.3 Which of the two band combinations best brought the
stadium and its field to prominence?
Question 11.4 Why did the band combination you chose best help in
viewing the stadium and the field? (Hint: You may want to do some brief
online research into the nature of the new stadium and its field.)
4. Return to the view of Cleveland’s waterfront area. You’ll now be
examining the water features (such as Lake Erie and the river). Paying
careful attention the water features, open four display windows and
expand and arrange them side by side to look at differences between
them. Create the following image composites (one for each window):
a. 3,2,1
b. 7,5,4
c. 4,2,1
d. 1,1,1
Question 11.5 Which band combination(s) best let you separate water
bodies from land? Why?
5. Return to the view of Cleveland’s waterfront area. Focus on the urban
features and vegetated features (zoom and pan where necessary to get
a good look at urbanization). Open new windows with some new band
combinations, noting how things change with each one as follows:
a. 7,4,2
b. 1,2,3
c. 4,3,2
Question 11.6 Which band combination(s) best let you separate urban
areas from other forms of land cover (that is, vegetation, trees, etc.)? Why?
6. Open a new display window and examine the full view of the
entire ‘clevsub’ image. Open this window with the following band
combination:
a. 6,6,6
7. Zoom in and move around the Cleveland waterfront area we’ve been
examining.
Question 11.7 Why is the image so “blurry” or “fuzzy” in this combination
(compared to all the other band combinations you’ve looked at in this
exercise)?
