Hi Everyone, While we're on the subject of Lat/Lon. In the toolbox
Projections and Transformations dialog box when converting from State Plane
to LL in the DATUM conversions drop down window there is a list NAD83 to
WSG84 numbered 1 to 5.  What's the difference?  Precision? Different parts of
the world or hemisphere?  Attempts by ESRI to get it right?  I use number 1
but often wonder what the others might do for me.   Just curious.  


Merry Christmas to all
