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 Ad Douiem
The DMS coordinates are: 14°0'4.3'' N 32°18'41.8'' E .
Calculations are easier by using the decimal format, hence:
LatO = 14.0012°
LngO = 32.3116°
Step 2: Calculate the latitude
LatA = - LatO = -14.0012°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 32.3116 - 180° = -147.6884°
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 Ad Douiem is located on coordinates: (LatA, LngA) = (-14.0012, -147.6884)
In DMS format: 14°0'4.3'' N 32°18'41.8'' E .
