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 Portland
The DMS coordinates are: 40°26'4.2'' N 84°58'39.9'' W.
Calculations are easier by using the decimal format, hence:
LatO = 40.43449°
LngO = -84.97775°
Step 2: Calculate the latitude
LatA = - LatO = -40.43449°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -84.97775 + 180° = 95.02225°
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 Portland is located on coordinates: (LatA, LngA) = (-40.43449, 95.02225)
In DMS format: 40°26'4.2'' N 84°58'39.9'' W.
