Can digital mapping reveal the logic behind history's greatest mistakes?

A digital reimagining of Gettysburg - Anne Knowles · 9:04 · Video: TED-Ed · Watch at the source

In short: Geographer Anne Knowles uses Geographic Information Systems (GIS) to reconstruct one of the most pivotal moments in American history. By layering modern technology over historical maps, she seeks to understand why Robert E. Lee made a catastrophic tactical error.

The video explores the Battle of Gettysburg, the decisive turning point of the Civil War. Knowles utilizes GIS and historical records to trace the specific movements of Robert E. Lee as he orchestrated Pickett's Charge.

By visualizing these maneuvers in a digital space, she provides an educated guess on why this crucial mistake occurred. This approach demonstrates how geographic data can offer new perspectives on human decision-making during high-stakes conflicts.
