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 Ghardaïa
The DMS coordinates are: 32°29'27.4'' N 3°40'24.5'' E .
Calculations are easier by using the decimal format, hence:
LatO = 32.49094°
LngO = 3.67347°
Step 2: Calculate the latitude
LatA = - LatO = -32.49094°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 3.67347 - 180° = -176.32653°
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 Ghardaïa is located on coordinates: (LatA, LngA) = (-32.49094, -176.32653)
In DMS format: 32°29'27.4'' N 3°40'24.5'' E .
