Can you make an Earth sandwich from Douala?
Nearly: a sloppy-grade Earth sandwich. The antipode of Douala lies in the South Pacific Ocean, 58 km from the nearest dry land. Sandwich Law allows a slice within 200 km of the true antipode, and the verifying grid rates Douala sloppy, so bread in Douala and bread near Atafu Village, Tokelau still count as one sandwich. The elevation bonus depends on the spot chosen for the dry slice.
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.
