Map layouts

• Lecture 3

6
Map layout elements

• Main map size and location
• Map title and subtitle
• what, where, and when
• Legend
• No need to label it Legend. Everyone will know
  what it is (this eliminates chart junk)
• Data sources
• Graphic scale

7
Map layout elements

• North arrow
• Rectangular boundary (neatline)
• Other elements
• Inset maps
• Data tables
• Charts
• Additional text
• Photographs

Fonts

• Style
• Simple and legible
• Formal or informal
• Number of fonts
• Placement
• Halos
• Contrasts background

13
Map scales

• Lecture 3

14
Map scales

• Map scale ratios
• Dimensionless
• Used with any linear measurement unit, such as
  feet, meters, or miles
• Example, 124,000
• Representative fraction
• 1 inch on the map is 24,000 inches on the ground
  (or 2,000 feet)

15
Map scales

• Graphic scale
• Graphic representation of map scale
• Places a line on the map with ground distances
  marked, such as 10 miles, 20 miles, etc.

16
Map scales

• 15,000 is large scale

150,000,000 is small scale

Map units

• Feet or meters is
• the map unit for
• most local
• government GIS applications

Map units
Inch is the map unit for most CAD applications
24
Multiple maps and output pages

• Lecture 3

25
Multiple maps

• Separate data frames

26
Multiple maps

• Separate layouts
• Same size
• Same scale
• Subtitles (optional)

27
Data driven pages

• Produces several maps from one layout
• Tools, customize, data-driven pages

28
Data-driven pages

• Layout textdata driven
