The antipode of
Qingdao.

Draw a straight line from Qingdao (36.06° N, 120.38° E) through the centre of the Earth and it comes out at 36.06° S, 59.62° W, on dry land in Argentina, 36 km from General Alvear. An exact Earth sandwich is possible.

Two globes: one centred on Qingdao, one centred on its antipode at 36.06° S, 59.62° W

Can you make an Earth sandwich from Qingdao?

Yes: an exact Earth sandwich. Qingdao 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 Qingdao and have a friend put one down 36 km from General Alvear, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 0 m: Qingdao sits at about sea level and the other slice about 40 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.
