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 Newcastle
The DMS coordinates are: 32°55'46.3'' S 151°46'48.4'' E .
Calculations are easier by using the decimal format, hence:
LatO = -32.92953°
LngO = 151.7801°
Step 2: Calculate the latitude
LatA = - LatO = 32.92953°
Since the latitude is negative (south direction), the antipode must be positive (north direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 151.7801 - 180° = -28.2199°
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 Newcastle is located on coordinates: (LatA, LngA) = (32.92953, -28.2199)
In DMS format: 32°55'46.3'' S 151°46'48.4'' E .
