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 Alexandria
The DMS coordinates are: 18°18'27.6'' N 77°21'12.1'' W.
Calculations are easier by using the decimal format, hence:
LatO = 18.30768°
LngO = -77.35335°
Step 2: Calculate the latitude
LatA = - LatO = -18.30768°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -77.35335 + 180° = 102.64665°
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 Alexandria is located on coordinates: (LatA, LngA) = (-18.30768, 102.64665)
In DMS format: 18°18'27.6'' N 77°21'12.1'' W.
