Actually, if you Google'd/Yahoo'd what I've highlighted in your original question above, you'd have gotten all the information you need without having pri knowledge that these are affectionately referred to as "Great Circle Calculations". Give it a try.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
     Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink
