Can you make an Earth sandwich from Yichang?
Yes: an exact Earth sandwich. Yichang 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 Yichang and have a friend put one down 53 km from San José de Jáchal, Argentina at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 1,280 m: Yichang sits about 120 m above sea level and the other slice about 1,160 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.
