o Visual hierarchy must enforce the intellectual hierarchy for the map to make the most sense. Make things that need to be understood pop out on the map. o Intellectual hierarchy: A list of what ideas and information are most important What is the map really about? o Visual hierarchy A list of what parts of the map are most prominent Which visual elements draw the eye and in what order? Balance on the page Where things are on the map How well you use the white space, the arrangement of the elements Can be used to create tension instead Looking for equilibrium and harmony Direction Where the eye is drawn to the optical center. It should be just above the geographic center of the page. Contrast It’s fucking contrast dude. Legibility Ability to see and understand all the elements o Includes appropriate symbols and symbol sizes o Appropriate size and types of labels o Intuitive color choice Figure vs. ground Figure: object in the foreground Ground: background You need to make sure that your reader can distinguish which is which. ESSENTIAL MAP ELEMENTS View (map) Title: What, where, and when Legend o Make sure its legible o Make sure it has units Scale North arrow (maybe) Data source and date Author’s name projection Discuss whether a map is using visual variables appropriately (3.1) o above Describe a critique of cartography or GIS, based on GIS & Society or Critical GIS research.
