The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of St Martin
The DMS coordinates are: 49°26'13.7'' N 2°33'17.2'' W.
Calculations are easier by using the decimal format, hence:
LatO = 49.43713°
LngO = -2.55479°
Step 2: Calculate the latitude
LatA = - LatO = -49.43713°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -2.55479 + 180° = 177.44521°
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 St Martin is located on coordinates: (LatA, LngA) = (-49.43713, 177.44521)
In DMS format: 49°26'13.7'' N 2°33'17.2'' W.
