I suppose if you feel that using SQL server to store locational information such as lat/long is "useless and pointless" then you'd feel that way about this question.

But for folks that need to work with such data, perhaps tracking movement of shipping containers (which can now 'phone home' using GPS/Satcom systems mounted on the container) or similar things, the relationship between units of distance, and the units used to store the locations can potentially be important.

Is that truely more trivial then some of the very obscure SQL details we've sometimes seen posted? I guess like art, that's in the eye of the beholder.
