thanks, I found that one but it's a litle *too* concise!  For instance, 
it doesn't actually say what a LINESTRING is.  I guess it's a series of 
straight line segments joined together, but I hate assuming things like 
that.

I can't be the first noob to be frustrated & annoyed by things described 
as "Well Known", without any explanation for those who don't know!
