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 Koolbaai
The DMS coordinates are: 18°2'25.7'' N 63°5'2.3'' W.
Calculations are easier by using the decimal format, hence:
LatO = 18.04048°
LngO = -63.08397°
Step 2: Calculate the latitude
LatA = - LatO = -18.04048°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -63.08397 + 180° = 116.91603°
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 Koolbaai is located on coordinates: (LatA, LngA) = (-18.04048, 116.91603)
In DMS format: 18°2'25.7'' N 63°5'2.3'' W.
