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 Onchan

The DMS coordinates are: 54°10'23.8'' N 4°27'11.7'' W.

Calculations are easier by using the decimal format, hence:

LatO = 54.17329°

LngO = -4.45324°

Step 2: Calculate the latitude

LatA = - LatO = -54.17329°

Since the latitude is positive (north direction), the antipode must be negative (south direction).

Step 3: Calculate the longitude

LngA = LngO ± 180° = -4.45324 + 180° = 175.54676°

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 Onchan is located on coordinates: (LatA, LngA) = (-54.17329, 175.54676)

In DMS format: 54°10'23.8'' N 4°27'11.7'' W.
