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 Ati
The DMS coordinates are: 13°12'49.7'' N 18°20'21.5'' E .
Calculations are easier by using the decimal format, hence:
LatO = 13.2138°
LngO = 18.3393°
Step 2: Calculate the latitude
LatA = - LatO = -13.2138°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 18.3393 - 180° = -161.6607°
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 Ati is located on coordinates: (LatA, LngA) = (-13.2138, -161.6607)
In DMS format: 13°12'49.7'' N 18°20'21.5'' E .
