Map Layouts
14
Map Layouts
  • Includes all of the elements of a stand alone map
  • Make the map the largest and most prominent
    element of the layout
  • Put a rectangular boundary around the map (called
    a neat line by cartographers) to help draw
    attention to it as the central element
  • Include a map title
  • The title needs to include information minimally
    answering the three questions what, where, and
    when.

15
Map Layouts (Continued)
  • Include a legend for symbols placed in the
    lower-right or left of the layout
  • No need to label it Legend. Everyone will know
    what it is (this eliminates chart junk)
  • Include data sources
  • Ensure legibility
  • Include a graphic map scale if your audience is
    not familiar with the area shown
  • Do not include a north arrow unless the top of
    your map is not north

16
Map Layouts (Continued)
  • Occasionally include other components as needed
    such as a data table listing, a frequency bar
    chart for the attribute of a choropleth map, or a
    photograph

Map Scales
23
Dimensionless Map Scales
  • ratio that relates a unit of measure on a map to
    some number of the same units of measure on the
    earth's surface
  • 125,000
  • tells us that 1 unit of measure 25,000 of the
    same units on the earth's surface
  • 1 on the map 25,000 inches on the earth's
    surface
  • one meter or one yard or one kilometer or one
    mile would represent 25,000 meters or yards or
    kilometers or miles, respectively, on the earth's
    surface.

24
Large and Small Scale Maps
  • 15,000 is large scale

150,000,000 is small scale
