CartographyGEO381/550

• Final Review
• December, 2nd 2004

2
Choropleth map

• How it works?
• When to use when not to use?
• Phenomenon
• Data
• Limitation? Solution to this?

3
Sample question

• Which of the following data is the most suitable
  for choropleth mapping?
• Temperature records at stations
• Number of hospital beds by county
• Average SAT scores by school district
• Total population by census tract
• Explain why

4
Proportional symbol map

• How it works?
• When to use when not to use?
• What is perceptual (apparent) scaling?
• What is range grading?

5
Sample question

• Suppose we have two values, 6400 and 1600, that
  are to be symbolized and scaled by proportional
  circles. The ratio of radius of proportional
  circles that represent two values would be 21
  when absolute scaling is adopted. What would
  happen to x in the ratio, say x1 when perceptual
  scaling is adopted?
• x will become larger than 2
• x will become smaller than 2

6
Sample question

• Suppose you have two maps in hand, whose maps
  have legends shown below. From the legends,
  discuss (1) data classification (2) the location
  of point symbols of respective map.

7
Dot density map

• How it works?
• When to use when not to use?
• Advantage disadvantage?

8
Sample question

• Data not suitable for dot density map?
• Number of farms
• Total population
• Property tax rate
• Number of AIDS cases

9
Sample question

• Suppose you are asked to make a dot density map
  of corn acreage data which is enumerated by
  state. When mapped in ArcView, it didnt turn out
  very well. What would you do in order to improve
  the quality of map, in particular locational
  accuracy?

10
Cartogram

• How it works?
• In which way, cartogram is fundamentally
  different from other mapping techniques?
• Advantage disadvantage?

11
Sample question

• In which of the following situations, would you
  consider cartogram to be an ideal choice?
• Map readers are not familiar with areas
• Data value is relatively proportional to the size
  of enumeration unit
• The more value is concentrated in the small
  enumeration unit
• Reference map

12
Sample question

• Which of the four geometric elements of
  enumeration units should be most strictly
  preserved?
• Size
• Contiguity
• Shape
• Orientation (relative location, order)

13
Role (function) of map

• Map visualization (visual thinking)
• Map communication (visual communication)

14
Sample question

• Suppose you are involved in two different
  projects One is to map 2000 Census (say spatial
  distribution of racial group), and the other is
  to map the volcanic process of Mt. Helena.
  Discuss the roles of two maps. How would
  different roles of maps affect the cartographic
  process?

15
Visual hierarchy

• What is?
• What is the psychological phenomenon underlying
  visual hierarchy?
• How to achieve visual hierarchy?

16
Color

• Spectral reflectance curve?
• Three psychological dimensions?
• Munsell color solid?
• Color primaries for display in computer screen?
• Map design implications of simultaneous/successive
  contrast?

17
Color

• How to promote efficient decoding of color?
• Brewer color schemata
• When you have population density data
• When you have historical economic data (increase,
  decrease)
• When you have bivariate historical economic data

18
Sample question

• Discuss how color is used to promote visual
  hierarchy in this map

19
Sample question

• Discuss color as visual variables in this map

20
Sample question

• How does hypsometric tint make the use of
  physical dimension of color (hue)?
• Illustrate how color convention conflicts with
  symbolical connotation of color from this map.

21
Typography
Black Letter Oldstyle Modern Sans serif

• Typeface classification

Pay attention to serif and shading
22
Sample question.

• Suppose you have to label two distinct features,
  say retail superstores, and castles in the
  greater London area. Which of the following pairs
  do you find the most appropriate match
  respectively?

A
B
C
D
23
Discuss the use of type form (italics, spacing,
case) in this map
