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 Portimão
The DMS coordinates are: 37°8'18.8'' N 8°32'15.9'' W.
Calculations are easier by using the decimal format, hence:
LatO = 37.13856°
LngO = -8.53775°
Step 2: Calculate the latitude
LatA = - LatO = -37.13856°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -8.53775 + 180° = 171.46225°
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 Portimão is located on coordinates: (LatA, LngA) = (-37.13856, 171.46225)
In DMS format: 37°8'18.8'' N 8°32'15.9'' W.
