Arguments

geography
Is another geography instance on which ReorientObject() is invoked.

Return Value

SQL Server return type: geography

CLR return type: SqlGeography

Remarks

This method changes the ring orientation of all Polygons in a GeometryCollection but doesn't remove or change any Points or LineStrings in the given collection.

If you pass a GeometryCollection to this method, each instance in the collection reorients as a result, but the whole collection doesn't reorient.

Examples

DECLARE @R GEOGRAPHY = GEOGRAPHY::Parse('Polygon((-10 -10, -10 10, 10 10, 10 -10, -10 -10))');  
SELECT @R.ReorientObject().STAsText();  
--Result: POLYGON ((10 10, -10 10, -10 -10, 10 -10, 10 10))
