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 Ouallam
The DMS coordinates are: 14°18'59.1'' N 2°5'9.5'' E .
Calculations are easier by using the decimal format, hence:
LatO = 14.31641°
LngO = 2.08597°
Step 2: Calculate the latitude
LatA = - LatO = -14.31641°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 2.08597 - 180° = -177.91403°
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 Ouallam is located on coordinates: (LatA, LngA) = (-14.31641, -177.91403)
In DMS format: 14°18'59.1'' N 2°5'9.5'' E .
