About
Countries on the Moon is an interactive 3D visualisation that places any country's outline onto the surface of the Moon, letting you compare its true size against the lunar landscape.
Built with Three.js and GeoJSON data from Natural Earth. Country polygons are projected using a spherical rotation algorithm that preserves shape and area at any scale.
How it works
Select a country from the dropdown. Its polygon is loaded from Natural Earth GeoJSON data and projected onto the Moon's surface.
Each vertex is placed directly on the sphere using spherical rotation, so the outline hugs the surface regardless of the country's size.
The country is scaled from its real Earth size using the ratio of Earth's radius (~6,371 km) to the Moon's radius (~1,737 km).
