A “time machine” is a plot device frequently used in science fiction. From H.G. Wells’ groundbreaking 1895 novel The Time Machine to Marty McFly’s use of a temporally-enabled DeLorean in Back to the Future, time travel has certainly captured our collective imagination. But the science behind time travel is dubious at best. And even though we can’t actually physically move backward or forward in time, we can at least experience some of the thrills—and benefits—of time travel through temporal analysis.
Geospatial professionals are well versed in visualization of spatial relationships and dependencies. But when looking for relationships and dependencies, examining proximity in time can be equally important. Pioneering environmental planner Ian McHarg put great emphasis on chronology, or the placing of geographic layers in chronological sequence to show relationships, dependencies, and causation through time.
