Grid Corrections: A Short Film Shows How Straight Roads Bend to Respond to Earth’s Curvature

That the flat Mercator projection maps we encounter in classrooms show a distorted view of our spherical planet is fairly well-known fact at this point. But the real-life application of grids on the earth takes a subtler form with the grid system of roads that defines much of the United States’ travelways. Dutch photographer and filmmaker Gerco de Ruijter created a short film called Grid Corrections that brings together dozens of aerial shots of rural roads. The film demonstrates how the grids are merged to accommodate the earth’s curvature through sharp dogleg turns every 24 miles. Grid Corrections will be screened at the Grasnapolsky music festival, which is February 2 – 4 in the town of Radio Kootwijk, The Netherlands. (via Kottke)
