The antipode can be calculated by understanding the geographic coordinates and applying simple formulas. We will use the following variables:
Step 1: Obtain the geographic coordinates of Songjiang
The DMS coordinates are: 31°2'3.9'' N 121°13'23.7'' E .
Calculations are easier by using the decimal format, hence:
LatO = 31.03443°
LngO = 121.22326°
Step 2: Calculate the latitude
LatA = - LatO = -31.03443°
Since the latitude is positive (north direction), the antipode must be negative (south direction).
Step 3: Calculate the longitude
LngA = LngO ± 180° = 121.22326 - 180° = -58.77674°
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 Songjiang is located on coordinates: (LatA, LngA) = (-31.03443, -58.77674)
In DMS format: 31°2'3.9'' N 121°13'23.7'' E .
