Antipode (Antipodal Point)
Technical Details & Mathematical Formulation
To calculate an antipode: invert the latitude sign and offset the longitude by 180 degrees. Because oceans cover 71% of Earth, only about 4% of terrestrial land has an antipode that is also on land.
\phi_{\text{anti}} = -\phi,\quad \lambda_{\text{anti}} = (\lambda + 180^\circ) \pmod{360^\circ} - 180^\circTest real-world coordinates and calculate live results in browser.
