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.
