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 San Antonio
The DMS coordinates are: 17°4'43'' N 89°1'25'' W.
Calculations are easier by using the decimal format, hence:
LatO = 17.07861°
LngO = -89.02361°
Step 2: Calculate the latitude
LatA = - LatO = -17.07861°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -89.02361 + 180° = 90.97639°
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 San Antonio is located on coordinates: (LatA, LngA) = (-17.07861, 90.97639)
In DMS format: 17°4'43'' N 89°1'25'' W.
