The antipode of
Qinzhou.

Draw a straight line from Qinzhou (21.98° N, 108.65° E) through the centre of the Earth and it comes out at 21.98° S, 71.35° W, in the South Pacific Ocean, 118 km from the nearest dry land, off the coast of Chile. A sloppy Earth sandwich is possible.

Two globes: one centred on Qinzhou, one centred on its antipode at 21.98° S, 71.35° W

Can you make an Earth sandwich from Qinzhou?

Nearly: a sloppy-grade Earth sandwich. The antipode of Qinzhou lies in the South Pacific Ocean, 118 km from the nearest dry land in Chile. Sandwich Law allows a slice within 200 km of the true antipode, and the verifying grid rates Qinzhou sloppy, so bread in Qinzhou and bread near Tocopilla, Chile 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.
