Name

geography — The type representing spatial features with geodetic (ellipsoidal) coordinate systems.

Description

geography is a spatial data type used to represent a feature in geodetic coordinate systems. Geodetic coordinate systems model the earth using an ellipsoid.

Spatial operations on the geography type provide more accurate results by taking the ellipsoidal model into account.
