Map layout elements


Main map size and location
Map title and subtitle
 What, where, and when
 Brief but descriptive

Legend
 No need to label it Legend. Everyone will know
what it is (this eliminates “chart junk”)


Data sources, credits
Rectangular boundary (neatline)

Map layout elements

North arrow
 Keep simple, discrete (avoid “compass rose”)


Graphic scale bar
Other elements of “map furniture”

MAP SCALES
INF385T(28437) – Spring 2013 – Lecture 3

Map scales
1:5,000 is large scale
INF385T(28437) – Spring 2013 – Lecture 3
1:50,000,000 is small scale
12
Map scales

Map scale ratios
 Dimensionless
 Used with any linear measurement unit, such as
feet, meters, or miles

Graphic scale, or “scale bar”
 Graphic representation of map scale
 Places a line on the map with ground distances
marked, such as 10 miles, 20 miles, etc.
