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 Saint-Louis
The DMS coordinates are: 21°17'9.1'' S 55°24'40.5'' E .
Calculations are easier by using the decimal format, hence:
LatO = -21.28585°
LngO = 55.41124°
Step 2: Calculate the latitude
LatA = - LatO = 21.28585°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 55.41124 - 180° = -124.58876°
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 Saint-Louis is located on coordinates: (LatA, LngA) = (21.28585, -124.58876)
In DMS format: 21°17'9.1'' S 55°24'40.5'' E .
