Problem: Projections in PC ARC/INFO don't line up with same projections done in ArcView
Solution or Workaround
Projecting from geographic to Stateplane NAD 83 does not produce the same results as doing the same projection with Projector! in ArcView 3.x.
The PROJECT command assumes an input datum of NAD 27 where as ArcView assumes
Make sure the Input PROJECT parameters include: DATUM NAD83 NADCON. For example:
DATUM NAD83 NADCON <------this line is added.
DATUM NAD83 NADCON
This DATUM definition will prevent the input from defaulting to NAD 27.
