Thematic Maps
Thematic Maps show a specific aspect and specialized information of an area while
maintaining the outline of a regular Map. Some examples of Thematic Maps are
those depicting regional climates, oceanic currents, or dispersion of something
such as disease. The aspects are typically
illustrated using colors or dots. For example, a map of regional climate usually
uses a scale from blue for cold regions to red or orange for hot regions. Dots
would be used to indicate dispersion. In any case, a legend is required.
Typical Uses
Thematic Maps can be especially useful when trying to compile information pertaining to
certain areas. Instead of writing it out or using charts and graphs, Thematic Maps allow
for a more straightforward and visual means of communicating the information.
Best Practices
- Determine the purpose. Decide what information the map will highlight. Gather the data necessary.
- Determine the area. Choose the area which the map will cover. For example, if the information only pertains to a city, then base your map only on that city.
- Create the map. Begin by drawing a regular map with boundaries and labels, although it may be helpful to leave out some details so that the map does not get overcrowded. Make sure it is accurately drawn. SmartDraw offers customizable Maps powered by Google to make this step quick and easy.
- Add specialized information. Add the chosen information to the map using colors or symbols.
- Create a legend. Find a blank or unimportant place on the page and place a box there. Use this box as a key to explain what each color or symbol represents so that the map is easy to understand.
- Verify accuracy. Consult with coworkers, employees, or team members to confirm the accuracy of the map.
