Advanced technology similar to Google Earth, MapQuest and the GPS systems used in millions of cars has made it possible to recreate a vanished landscape. This new generation of digital maps has given rise to an academic field known as spatial humanities. Historians, literary theorists, archaeologists and others are using Geographic Information Systems — software that displays and analyzes information related to a physical location — to re-examine real and fictional places like the villages around Salem, Mass., at the time of the witch trials; the Dust Bowl region devastated during the Great Depression; and the Eastcheap taverns where Shakespeare’s Falstaff and Prince Hal caroused.
Like the crew on the starship Enterprise, humanists are exploring a new frontier of the scholarly universe: space.
“Mapping spatial information reveals part of human history that otherwise we couldn’t possibly know,” said Anne Kelly Knowles, a geographer at Middlebury College in Vermont. “It enables you to see patterns and information that are literally invisible.” It adds layers of information to a map that can be added or taken off at will in various combinations; the same location can also be viewed back and forth over time at the click of a mouse.
