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 Ratnapura

The DMS coordinates are: 6°41'8.9'' N 80°24'13'' E .

Calculations are easier by using the decimal format, hence:

LatO = 6.6858°

LngO = 80.4036°

Step 2: Calculate the latitude

LatA = - LatO = -6.6858°

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

Step 3: Calculate the longitude

LngA = LngO ± 180° = 80.4036 - 180° = -99.5964°

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 Ratnapura is located on coordinates: (LatA, LngA) = (-6.6858, -99.5964)

In DMS format: 6°41'8.9'' N 80°24'13'' E .
