Chapter 3 Review Questions
1. List four questions about map objectives that would influence the design of a map.
What am I making this map for and what am I trying to acomplish?
Who will be viewing?
Why will it be used?
Is there privacy issues surrounding the project?
2. What factors should be considered in evaluating the balance of a map?
Placement of features, the size of features, alignment of features, usage of space
3. What types of colors generally work best for maps? How can the psychology of colors be used to enhance a map’s meaning?
Pastels and earth are good for big map areas. Bold colors are good for emphasis.
Some things have associations with colors. For example green for plant life or blue for water
4. List three common pitfalls that amateurs make when creating legends.
Cryptic filenames, poor formatting of numeric numbers and not adjusting neatlines for balance
5. What is a geographic coordinate system, and why is it a poor choice for creating maps? this is a bad method for making maps because of the distortion the system makes when projecting the map. A geographic coordinate system does this because it is a system based on a sphere.
6. What four properties are distorted by map projections? Which tend to be preserved by conic projections? What distortions are present in UTM and State Plane projections?
Area Shape Direction and Distance can all be distorted. UTM and state plane are better for small area mapping as they tend to preserve area and distance.
7. Examine the map projections on the inside front cover of this text. List which projection(s) might be suitable for a (a) map of a county, (b) map of the United States, (c) United States map used to calculate travel distances, and (d) United States map used to calculate areas.
a)= UTM or state plane
b)= Equidistant Conic or lamber conformal conic
c)= Equidistant Conic
d)= Albers Equal Area Conic
8. When does a north arrow not point up? When should a north arrow not be
