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 San Diego
The DMS coordinates are: 32°42'56.6'' N 117°9'53'' W.
Calculations are easier by using the decimal format, hence:
LatO = 32.71571°
LngO = -117.16472°
Step 2: Calculate the latitude
LatA = - LatO = -32.71571°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -117.16472 + 180° = 62.83528°
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 San Diego is located on coordinates: (LatA, LngA) = (-32.71571, 62.83528)
In DMS format: 32°42'56.6'' N 117°9'53'' W.
