The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of Watthana
The DMS coordinates are: 13°43'47.2'' N 100°35'7.3'' E .
Calculations are easier by using the decimal format, hence:
LatO = 13.72978°
LngO = 100.58536°
Step 2: Calculate the latitude
LatA = - LatO = -13.72978°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 100.58536 - 180° = -79.41464°
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 Watthana is located on coordinates: (LatA, LngA) = (-13.72978, -79.41464)
In DMS format: 13°43'47.2'' N 100°35'7.3'' E .
