Hi wbrianwhite,

I have looked at the geometry and geography data types / support in the later versions of SQL Server.

I don't feel that I'm familiar enough yet to comment conclusively one way or the other.

My initial tests with geography data types did not seem to perform near as well as the basic udf function outlined in the article. There may be a lot more than what "meets the eye" here though so further investigation will continue when time permits.
