Worth 10 Points and a wealth of insight for the exam and/or lab assignment
This assignment has you make a connection between the concepts presented in
lecture and the methods you used in all of your previous lab assignments.
The focus is on "Flow Maps". If
you so choose, the essay you write in activity can be used to help you prepare
for the exam and/or next lab assignment. Assignment is due the day that
follows the respective in-class discussion.
1. Consider the following three questions and
ask yourself if you understand what is being asked. You may refer to your
notes, hand-outs, and readings as appropriate.
a. Discuss how you would map nominal data as airline routes between
cities, or ordinal data as routes with more or less comfort based on passenger
satisfaction, or interval data as the number on airline passengers flying
between cities. What type of flow map as
discussed in lecture would you use to do this?
b. Three types of flow maps were discussed in lecture, network, radial, and
distributive. How might you use each of three types to map
transportation-related data such as traffic data in the Central Puget Sound
Region? You might have to consider more types of phenomena than treated in the lab assignment.
c. Map legends are suggested to be the "key" to the information on
the map. Suggest at least three alternative legend designs that could be
used on your traffic flow map of Central Puget Sound.
Discuss the advantages and disadvantages of at least two of them.
2. Type up a 5-minute essay makeup – about one-half page for each of
the three questions. Please repeat the questions at the beginning of each
answer.
3. Turn in your essay on the class day after the in-class essay. The
essay will be returned as soon after it is turned in for grading as possible. .
