Antipode finder · China

The antipode of
Bao'an.

Draw a straight line from Bao'an (22.55° N, 113.88° E) through the centre of the Earth and it comes out at 22.55° S, 66.12° W, on dry land in Argentina, 13 km from Rinconada. An exact Earth sandwich is possible.

Two globes: one centred on Bao'an, one centred on its antipode at 22.55° S, 66.12° W

Can you make an Earth sandwich from Bao'an?

Yes: an exact Earth sandwich. Bao'an 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 Bao'an and have a friend put one down 13 km from Rinconada, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 3,760 m: Bao'an sits about 40 m above sea level and the other slice about 3,720 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.
