Can you make an Earth sandwich from Surabaya?
Yes: an exact Earth sandwich. Surabaya 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 Surabaya and have a friend put one down 59 km from San Juan de Payara, Venezuela at the same UTC minute, and the whole planet is the filling. The elevation bonus would be about 80 m: Surabaya sits about 40 m above sea level and the other slice about 40 m above sea level.
Surabaya is on the Indonesia & Malaysia ↔ Colombia, Ecuador & the Amazon corridor. Its guide lists where every city on both sides lands and how to make an Earth sandwich there.
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.
