Formula and methodology
Formula: Antipode latitude = −latitude; antipode longitude = longitude+180 wrapped into [−180°,180°].
The transformation identifies the diametrically opposite point on an ideal spherical Earth.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Latitude — degrees; minimum -90; maximum 90
- Longitude — degrees; minimum -180; maximum 180
Worked example
| Input | Value |
|---|---|
| Latitude | 25.3 |
| Longitude | -80.2 |
Antipode = latitude −25.3°, longitude 99.8°.
Assumptions and limits
- Latitude and longitude use degrees with latitude in [−90,90] and longitude in [−180,180].
- The Earth is treated as a sphere and longitude is wrapped at the date line.
- Geodetic datum, elevation, coastlines, time zones, and navigational routing are not modeled.
