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 Port-Olry
The DMS coordinates are: 15°2'30.3'' S 167°4'21.5'' E .
Calculations are easier by using the decimal format, hence:
LatO = -15.04175°
LngO = 167.07265°
Step 2: Calculate the latitude
LatA = - LatO = 15.04175°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 167.07265 - 180° = -12.92735°
Since the longitude is positive, we subtract 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would sum 180° for the same reason.
The antipode of Port-Olry is located on coordinates: (LatA, LngA) = (15.04175, -12.92735)
In DMS format: 15°2'30.3'' S 167°4'21.5'' E .
