Spatial functions
Relationships between geometry objects are based on the Dimensionally Extended
nine-Intersection Model (DE-9IM). This model defines predicates such as equals, contains,
and
covers. For more information about the definition of spatial relationships, see DE-9IM
Amazon Redshift supports the following spatial functions.
