The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:

*Lat*: Latitude at the origin point._{O}*Lng*: Longitude at the origin point._{O}*Lat*: Latitude at the antipodal point._{A}*Lng*: Longitude at the antipodal point._{A}

Step 1: Obtain the geographic coordinates of Port-Olry

The DMS coordinates are: 15°2'30.3'' S 167°4'21.5'' E .

Calculations are easier by using the decimal format, hence:

*Lat _{O}*

*Lng _{O}*

Step 2: Calculate the latitude

*Lat _{A}*

Since the latitude is negative (south direction), the antipode must be positive (north direction).

Step 3: Calculate the longitude

*Lng _{A}*

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 Port-Olry is located on coordinates: (*Lat _{A}*,

In DMS format: 15°2'30.3'' S 167°4'21.5'' E .
