The antipode of
Weinan.

Draw a straight line from Weinan (34.50° N, 109.51° E) through the centre of the Earth and it comes out at 34.50° S, 70.49° W, on dry land in Chile, 33 km from Coya. An exact Earth sandwich is possible.

Two globes: one centred on Weinan, one centred on its antipode at 34.50° S, 70.49° W

Can you make an Earth sandwich from Weinan?

Yes: an exact Earth sandwich. Weinan is one of the few large cities with dry land directly opposite it. The grid that verifies submissions rates the spot exact: put a slice down in Weinan and have a friend put one down 33 km from Coya, Chile at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 2,880 m: Weinan sits about 440 m above sea level and the other slice about 2,440 m above sea level.

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.
