Digital Maps Are Giving Scholars the Historical Lay of the Land

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.
