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: 31°12'6.3'' N 29°54'57'' E .
Calculations are easier by using the decimal format, hence:
LatO = 31.20176°
LngO = 29.91582°
Step 2: Calculate the latitude
LatA = - LatO = -31.20176°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 29.91582 - 180° = -150.08418°
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 Alexandria is located on coordinates: (LatA, LngA) = (-31.20176, -150.08418)
In DMS format: 31°12'6.3'' N 29°54'57'' E .
