Antipode finder · China

The antipode of
Yangzhou.

Draw a straight line from Yangzhou (32.40° N, 119.44° E) through the centre of the Earth and it comes out at 32.40° S, 60.56° W, on dry land in Argentina, 37 km from Diamante. An exact Earth sandwich is possible.

Two globes: one centred on Yangzhou, one centred on its antipode at 32.40° S, 60.56° W

Can you make an Earth sandwich from Yangzhou?

Yes: an exact Earth sandwich. Yangzhou 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 Yangzhou and have a friend put one down 37 km from Diamante, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 80 m: Yangzhou sits about 40 m above 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.
