ST_LatSouth method for type ST

geometry-expression.ST_LatSouth()

DOUBLE Returns the southernmost latitude of the geometry-expression.

Returns the southernmost latitude value of the geometry-expression. Note that in the round-Earth model, the southernmost latitude may not correspond to the latitude of any of the points defining the geometry.

Note

If the geometry-expression is an empty geometry (ST_IsEmpty()=1), then this method returns NULL.

Note

By default, ST_LatSouth uses the original format for a geometry, if it is available. Otherwise, the internal format is used. For more information about internal and original formats, see STORAGE FORMAT clause, CREATE SPATIAL REFERENCE SYSTEM statement.
