16. CIRCULARSTRING (0 50, 90 50, 180 50, 270 50, 0 50) CURVEPOLYGON (CIRCULARSTRING (0 50, 90 50, 180 50, 270 50, 0 50)) If a circular linestring encloses an area, a curve polygon can be created Coordinate pair order is important for the geography type. This set of coordinates is ordered according to the “left foot rule” for exterior rings.

17. Both types provide static and instance methods Calculate distances, find intersections, etc. SELECT StreetName FROM Streets WHERE Streets.StreetGeo.STIntersects(@ms) = 1 Find streets that intersect the Microsoft campus

20. BufferWithCurves() DECLARE @g GEOGRAPHY = GEOGRAPHY::STGeomFromText('CIRCULARSTRING(0 50, 45 50, 90 50)',4326) DECLARE @b GEOGRAPHY = @g.BufferWithCurves(500000) SELECT @b.STNumPoints() --Number of vertices: 11 DECLARE @g GEOGRAPHY = GEOGRAPHY::STGeomFromText('CIRCULARSTRING(0 50, 45 50, 90 50)',4326) DECLARE @b GEOGRAPHY = @g.STBuffer(500000) SELECT @b.STNumPoints() --Number of vertices: 257 This method will construct the resulting polygon with circular arcs, often resulting in a dramatically smaller spatial object.

21. ReorientObject This method will reverse the order of coordinates which define polygon rings. This method is a NoOp on line strings, circular arcs and points. This method does only work with the GEOGRAPHY type.
