Maps, Aerial Photographs, and Satellite Images - Investigations in Environmental Geology - page 33

San Francisco, California
The following questions refer to Figure 2.16, which is a satellite
image of the San Francisco Bay area. The dots and small circles
are earthquake epicenters, which are discussed in Exercise 7.

18. Locate examples of the following land uses on the satel-
lite image. Mark these features and a north arrow on the
outline map of the San Francisco Bay area (Figure 2.17
(back cover)):
a. bridges across San Francisco Bay
b. airport(s)
c. an urban park
d. a major highway
e. elongated lakes along the San Andreas Fault

19. What pattern differences help distinguish natural veg-
etation areas from vegetation patterns in agricultural
areas?

20. Compare natural and human features on this satellite
image with those on the black and white and color stereo
photographs. What are some of the advantages and dis-
advantages of using satellite images rather than aerial
photographs in environmental studies? Under what condi-
tions do you think that satellite images might be especially
useful?

interpretation of Figure 2 .17.

23. How does having a topographic map help interpret
human-related features on a LIDAR image?

Bainbridge Island near Seattle, Washington.
21. What are the kinds of features that can more easily be
seen on the LIDAR image than on the topographic map?
Which of these features are natural and which are related to
human activity? What is your evidence?

24. When would the use of each type of map be an advan-
tage? A disadvantage?

22. What are the kinds of features that can more easily be seen
on the topographic map than on the LIDAR image?
