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 Honiara
The DMS coordinates are: 9°25'60'' S 159°56'60'' E .
Calculations are easier by using the decimal format, hence:
LatO = -9.43333°
LngO = 159.95°
Step 2: Calculate the latitude
LatA = - LatO = 9.43333°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 159.95 - 180° = -20.05°
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.
The antipode of Honiara is located on coordinates: (LatA, LngA) = (9.43333, -20.05)
In DMS format: 9°25'60'' S 159°56'60'' E .
