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 Portlaoise
The DMS coordinates are: 53°2'3.9'' N 7°17'59.2'' W.
Calculations are easier by using the decimal format, hence:
LatO = 53.03441°
LngO = -7.29979°
Step 2: Calculate the latitude
LatA = - LatO = -53.03441°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = -7.29979 + 180° = 172.70021°
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 Portlaoise is located on coordinates: (LatA, LngA) = (-53.03441, 172.70021)
In DMS format: 53°2'3.9'' N 7°17'59.2'' W.
