Can you make an Earth sandwich from Diyarbakır?
No, not from Diyarbakır itself. The other slice would land in the South Pacific Ocean, 1,166 km from the nearest dry land, where the sea floor lies about 5,000 m below the surface. Boats do not count (Sandwich Law § 1.3).
The nearest place from which an exact Earth sandwich is possible is 1,803 km from Diyarbakır, 32 km from Jeddah, Saudi Arabia. Its other slice would go down 403 km from Otepa, French Polynesia.
How this was worked out: the antipode flips the latitude and moves the longitude by 180°. Land or sea comes from the OpenStreetMap coastline the map uses; the sandwich verdict and elevations come from the verifier's 0.2° grid (Natural Earth land, ETOPO 2022 relief); water names from Natural Earth; towns and populations from GeoNames. The city's position is GeoNames' point for it; a big city's suburbs spread tens of kilometres around that point, and the figures move with them. Generated 2026-09-29.
