Elements of a Map

Map elements

Maps communicate using various visual devices. Along with balance, composition, and the effective use of white space, the following elements are often used to enhance map communication.

Borders or neat lines: A fine line often encloses a map unless the map content provides a strong contrast with the page. Other lines may be necessary in the figure to emphasize hierarchy and focus.

Title: Include either on the map or in a figure caption. A subtitle is sometimes useful.  **The word “Map” in the map title is unnecessary (it is obviously a map).

North arrow: A north arrow is useful on maps oriented in a direction other than north or for very large-scale maps.

Graticule: A graticule is a representation of meridians of longitude and parallels of latitude on a map. It is useful for orientation and for visualizing the projection used on the map.

Scale: Maps may include a scale bar or verbal/numeric scale. The map scale varies throughout a map depending on the projection used, particularly on small-scale maps. A variable scale bar may be used on maps with large-scale variations, but omitting a graphic scale bar altogether may also be appropriate.

Inset maps: Inset maps are useful for providing a broader context to the information on the main map. They can be at a smaller or larger scale than the main map.

Type: Type refers to the labels put on a map. Typography is the process of selecting and stylizing labels. Changes in type family, typestyle, type size, lettering and word spacing, color, and orientation create visual contrast between more important and less important typographical map content.

Legend: A legend explaining the map symbols should be included. The legend should be easy to understand and self-explanatory. The following practices are generally applicable to legends for thematic data:

  • Legend symbols should match their corresponding map symbols exactly.
  • Items in the legend should be placed in a logical order based on the data.
  • Ranges of numbers can be separated by a dash or by the word “to,” which is useful for avoiding consecutively placed dashes when negative numbers are present.
  • Numbers over 1,000 should include commas; numbers less than 1 should include a leading zero before the decimal point.

**The word “Legend” as a legend heading is unnecessary (the legend is obvious).
**Remove ArcGIS default legend headings (e.g., “mort_rate_cvh_09”). Use something that is intuitive to all map readers.
**Using “Percent” in the map title and “Percentage” as a legend heading is not recommended. Instead, titles should use “Percentage,” and legend headings should use “Percent.”

Other items: Data sources, dates, information about data processing, and, if required, map status (draft, final, etc.) should be indicated in the legend or elsewhere. To achieve a unified look and instant recognition, the CDC has developed a brand identity that requires specific logos and other graphic elements. For more information, see Brand Identity Standards.
