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 San Juan
The DMS coordinates are: 15°21'55'' S 75°9'44'' W.
Calculations are easier by using the decimal format, hence:
LatO = -15.36528°
LngO = -75.16222°
Step 2: Calculate the latitude
LatA = - LatO = 15.36528°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -75.16222 + 180° = 104.83778°
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 San Juan is located on coordinates: (LatA, LngA) = (15.36528, 104.83778)
In DMS format: 15°21'55'' S 75°9'44'' W.
