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 Jamestown

The DMS coordinates are: 15°56'19.4'' S 5°43'0.3'' W.

Calculations are easier by using the decimal format, hence:

LatO = -15.93872°

LngO = -5.71675°

Step 2: Calculate the latitude

LatA = - LatO = 15.93872°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = -5.71675 + 180° = 174.28325°

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 Jamestown is located on coordinates: (LatA, LngA) = (15.93872, 174.28325)

In DMS format: 15°56'19.4'' S 5°43'0.3'' W.
