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 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.

Result:

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 .
