Thanks Ed,
     I've been given lat/long values which i assumed were NAD83.  Could you
suggest any other datums to try?
thx,
Paul

Paul -

Can you explain in a little more detail?  Projections by their very nature
shift (i.e. "project") point coordinates.  If you're seeing points show up
in a slightly incorrect place, you've probably got the wrong datum for your
source data.

Hi,
    I was wondering if anyone would know why points would be shifted down
slightly in a projection?
