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 Southend-on-Sea
The DMS coordinates are: 51°32'16.2'' N 0°42'51.6'' E .
Calculations are easier by using the decimal format, hence:
LatO = 51.53782°
LngO = 0.71433°
Step 2: Calculate the latitude
LatA = - LatO = -51.53782°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 0.71433 - 180° = -179.28567°
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 Southend-on-Sea is located on coordinates: (LatA, LngA) = (-51.53782, -179.28567)
In DMS format: 51°32'16.2'' N 0°42'51.6'' E .
