Open the map editorThe antipode of a place is the point on the opposite side of the Earth. If you drew a straight line from your location through the center of the planet, it would come out at the antipode. Treating the Earth as a sphere, the calculation is simple: the antipodal latitude is the same number with the opposite sign, and the antipodal longitude is shifted by 180 degrees.
Enter a latitude and longitude in decimal degrees. Latitude runs from -90 (south pole) to 90 (north pole), and longitude from -180 to 180, with negative values meaning south and west. You can also paste a pair such as 48.8566, 2.3522 into the latitude box and it will be split across both fields. Anything that is not a number in range shows an inline message instead of a result.
Water covers most of the planet, so for most land locations the opposite point falls in open sea. The tool checks both points against the country boundaries on this site and tells you which country each is in. When it reports open ocean, the point is not inside any country polygon in our data, which is simplified, so small islands and coastlines can be missed near the edge.
People look up antipodes out of curiosity, for classroom geography exercises, or to plan a visual, such as a graphic showing two opposite points on a globe. The GeoJSON output holds both points in one MultiPoint feature, ready to drop into a mapping tool. Because the math assumes a perfect sphere, results can differ slightly from an ellipsoidal model, which is fine for any everyday use.
