How to calculate the antipodal point?
The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
- LatO: Latitude at the origin point.
- LngO: Longitude at the origin point.
- LatA: Latitude at the antipodal point.
- LngA: Longitude at the antipodal point.
Step 1: Obtain the geographic coordinates of Grand Forks
The DMS coordinates are: 49°1'59.1'' N 118°26'8.2'' W.
Calculations are easier by using the decimal format, hence:
LatO = 49.03309°
LngO = -118.4356°
Step 2: Calculate the latitude
LatA = - LatO = -49.03309°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -118.4356 + 180° = 61.5644°
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 Grand Forks is located on coordinates: (LatA, LngA) = (-49.03309, 61.5644)
In DMS format: 49°1'59.1'' N 118°26'8.2'' W.
