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 Welisara
The DMS coordinates are: 7°1'41.2'' N 79°54'5'' E .
Calculations are easier by using the decimal format, hence:
LatO = 7.0281°
LngO = 79.9014°
Step 2: Calculate the latitude
LatA = - LatO = -7.0281°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 79.9014 - 180° = -100.0986°
Since the longitude is positive, we subtract 180° to ensure the final value lies between (-180, 180). If it were the other way around, we would sum 180° for the same reason.
Result:
The antipode of Welisara is located on coordinates: (LatA, LngA) = (-7.0281, -100.0986)
In DMS format: 7°1'41.2'' N 79°54'5'' E .
