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 Koidu
The DMS coordinates are: 8°38'37.9'' N 10°58'17'' W.
Calculations are easier by using the decimal format, hence:
LatO = 8.64387°
LngO = -10.9714°
Step 2: Calculate the latitude
LatA = - LatO = -8.64387°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -10.9714 + 180° = 169.0286°
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 Koidu is located on coordinates: (LatA, LngA) = (-8.64387, 169.0286)
In DMS format: 8°38'37.9'' N 10°58'17'' W.
