The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of Neiafu
The DMS coordinates are: 18°39'2.2'' S 173°59'2.5'' W.
Calculations are easier by using the decimal format, hence:
LatO = -18.6506°
LngO = -173.98404°
Step 2: Calculate the latitude
LatA = - LatO = 18.6506°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -173.98404 + 180° = 6.01596°
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.
The antipode of Neiafu is located on coordinates: (LatA, LngA) = (18.6506, 6.01596)
In DMS format: 18°39'2.2'' S 173°59'2.5'' W.
