The antipode of
Huaibei.

Draw a straight line from Huaibei (33.97° N, 116.79° E) through the centre of the Earth and it comes out at 33.97° S, 63.21° W, on dry land in Argentina, 21 km from La Cesira. An exact Earth sandwich is possible.

Can you make an Earth sandwich from Huaibei?

Yes: an exact Earth sandwich. Huaibei 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 Huaibei and have a friend put one down 21 km from La Cesira, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 160 m: Huaibei sits about 40 m above sea level and the other slice about 120 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.
