gives the antipodal position of location loc.
gives the antipodal primitive of the geo primitive g.
- The location loc in GeoAntipode[loc] can be a GeoPosition, GeoGridPosition or other position object. It can also be a geo Entity object.
- For a geo primitive g, GeoAntipode[g] returns the antipodal primitive, with locations in g being replaced by their antipodal locations.

Properties & Relations (4)
The antipode of the antipode of a location is the original location:
If location p is east of location q, then the antipode of p is also east of the antipode of q:
However, if p is north of q, then the antipode of p is south of the antipode of q:
The day and night hemispheres for a given date are antipodal:
The day-night terminator is its own antipode:
The geo hemispheres of two antipodal locations are complementary:
