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)
4INF385T(28437) – Spring 2013 – Lecture 3
Map layout elements North arrow
Keep simple, discrete (avoid “compass rose”)
Graphic scale bar Other elements of “map furniture”
Inset maps Data tables Charts Additional text Photographs

Map scales
INF385T(28437) – Spring 2013 – Lecture 3
1:5,000 is large scale1:50,000,000 is small scale
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.
