Cartographic design choices are well done when they are largely unnoticed by the map user. On maps that are to be used—rather than simply admired for their artistry—the color palette, icons, lines, and layers of information should work together seamlessly to create a clear, accurate, and logical picture of the world.
Google Maps and other online maps provide information about the world’s largest cities and most isolated places. We can plan driving or walking routes, locate local businesses, and “see” the cultural and physical features of a place, all with unprecedented ease. Imagine the challenge of finding a detailed map of Budapest, for example, just ten years ago. Now online street maps and satellite views are available in mere seconds.
Willem Van Lancker, “a user experience and visual designer,” and Jonah Jones, “the lead user experience designer,” for Google Maps recently described the cartographic evolution of Google’s maps in Core77, on online design magazine. They described the challenges Google faces in designing a map that is useful for both local residents and visitors in countries around the world.
As Google Maps has broadened in scope, we have also had to address fundamental differences in tasks as basic as navigation and driving directions. We have found that, generally speaking, people navigate primarily by street names in Western countries and by landmarks and points of interest in the East. This is due to a combination of factors including a lack of road names (e.g. in India where locals rely on landmarks) or just a more complex street addressing system (e.g. in Japan where street numbers are assigned by date of construction, not sequentially).
The Van Lancker and Jones article also gives insight into the challenges associated with selecting internationally recognized symbols and how the veins on a leaf helped inspire Google’s “hybrid” maps, which overlay major roads onto satellite imagery.
