How to calculate the antipodal point?
The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
- LatO: Latitude at the origin point.
- LngO: Longitude at the origin point.
- LatA: Latitude at the antipodal point.
- LngA: Longitude at the antipodal point.
Step 1: Obtain the geographic coordinates of Haapiti
The DMS coordinates are: 17°33'48.7'' S 149°52'8.6'' W.
Calculations are easier by using the decimal format, hence:
LatO = -17.56352°
LngO = -149.86905°
Step 2: Calculate the latitude
LatA = - LatO = 17.56352°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -149.86905 + 180° = 30.13095°
Since the longitude is negative, we sum 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would subtract 180° for the same reason.
Result:
The antipode of Haapiti is located on coordinates: (LatA, LngA) = (17.56352, 30.13095)
In DMS format: 17°33'48.7'' S 149°52'8.6'' W.
