Geography vectors are arrays of points, lines, polygons, and/or collections of these. Geography vectors assume coordinates are longitude and latitude on a perfect sphere.

An object with class s2_geography

The coercion function `as_s2_geography()`

is used to wrap the input
of most functions in the s2 package so that you can use other objects with
an unambiguious interpretation as a geography vector. Geography vectors
have a minimal vctrs implementation, so you can
use these objects in tibble, dplyr, and other packages that use the vctrs
framework.
