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 Honiara

The DMS coordinates are: 9°25'60'' S 159°56'60'' E .

Calculations are easier by using the decimal format, hence:

LatO = -9.43333°

LngO = 159.95°

Step 2: Calculate the latitude

LatA = - LatO = 9.43333°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = 159.95 - 180° = -20.05°

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 Honiara is located on coordinates: (LatA, LngA) = (9.43333, -20.05)

In DMS format: 9°25'60'' S 159°56'60'' E .
