Azure SQL Database
Azure SQL Managed Instance
Returns a geography instance with interchanged interior regions and exterior regions.
This geography data type method supports FullGlobe instances or spatial instances that are larger than a hemisphere.
Syntax
.ReorientObject (geography)
Arguments
geography
Is another geography instance on which ReorientObject()
is invoked.
Return Value

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))
