South-up interactive map
The World Upside Down
This south-up map turns the familiar world view through 180°. South appears at the top, while north points toward the bottom of the screen.
The arrangement may feel strange because most contemporary world maps place north at the top. That choice is a cartographic convention rather than a physical property of Earth. In physics, “down” can be defined locally by gravity, while astronomy and spaceflight use stated reference frames because space has no single universal up or down.
Drag to move across the world and use the zoom controls to inspect familiar places from an unfamiliar direction. The compass remains visible so the map can be read without losing geographic orientation.
Why does the world look wrong when south is at the top?
Repeated exposure builds a strong mental association between north and the upper edge of a map. Rotating the map preserves locations and spatial relationships, although the visual hierarchy and the way we scan continents change immediately.
Projection and limitations
The OpenStreetMap tiles use Web Mercator. This familiar web projection enlarges high latitudes and does not include the exact geographic poles, so the map is intended for orientation and exploration rather than area comparison or polar measurement.
