Can you make an Earth sandwich from Hengyang?
Yes: an exact Earth sandwich. Hengyang 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 Hengyang and have a friend put one down 58 km from Puerta de Corral Quemado, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 4,160 m: Hengyang sits about 40 m above sea level and the other slice about 4,120 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.
