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 Ponérihouen
The DMS coordinates are: 21°4'60'' S 165°24'0'' E .
Calculations are easier by using the decimal format, hence:
LatO = -21.08333°
LngO = 165.4°
Step 2: Calculate the latitude
LatA = - LatO = 21.08333°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 165.4 - 180° = -14.6°
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 Ponérihouen is located on coordinates: (LatA, LngA) = (21.08333, -14.6)
In DMS format: 21°4'60'' S 165°24'0'' E .
