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 Helao Nafidi
The DMS coordinates are: 17°23'35.6'' S 15°53'27.9'' E .
Calculations are easier by using the decimal format, hence:
LatO = -17.39321°
LngO = 15.89107°
Step 2: Calculate the latitude
LatA = - LatO = 17.39321°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 15.89107 - 180° = -164.10893°
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 Helao Nafidi is located on coordinates: (LatA, LngA) = (17.39321, -164.10893)
In DMS format: 17°23'35.6'' S 15°53'27.9'' E .
