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 Saint-Louis
The DMS coordinates are: 16°1'4.5'' N 16°29'22.6'' W.
Calculations are easier by using the decimal format, hence:
LatO = 16.01793°
LngO = -16.48962°
Step 2: Calculate the latitude
LatA = - LatO = -16.01793°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -16.48962 + 180° = 163.51038°
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.
The antipode of Saint-Louis is located on coordinates: (LatA, LngA) = (-16.01793, 163.51038)
In DMS format: 16°1'4.5'' N 16°29'22.6'' W.
