Each Shadow Map begins with a historical hand-drawn survey — the kind of map made before satellites, where every contour line was the result of a person standing in terrain and measuring it. I take these digitized originals and align them with contemporary elevation models derived from satellite data. From this alignment, I calculate the average shadow that would be cast across a specific time period. The shadow map is then overlaid onto the historical map. Where geography has stayed the same, the shadow follows the original contours faithfully. Where the land has changed — eroded, built upon, altered — the shadow diverges from the drawn lines beneath it. The 3D effect is not stylistic. It is the record of a discrepancy between two moments in time. These works are an act of attention toward the original mapmakers — their precision, their fieldwork, their artistry — seen through the lens of what we know now.
