ST_LongEast method for type ST

geometry-expression.ST_LongEast()

DOUBLE Retrieves the longitude of the eastern boundary of the geometry-expression.

Returns the longitude of the eastern boundary of the geometry-expression. If the geometry crosses the date line in the round-Earth model, ST_LongWest will be higher than the ST_LongEast value.

Note

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

Note

By default, ST_LongEast 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.
