I'm not aware of any converters between ARC/INFO and netCDF.

The netCDF data model may not be rich enough to represent arbitrary
ARC/INFO data, especially if the latter uses nested data structures or
requires multiple unlimited dimensions.  I think it would be possible to
develop conventions for representing static ARC/INFO data using netCDF,
but supporting efficient updates might be difficult, e.g. adding the
data for new county outlines to an existing file.

You might want to pose your question to the address@hidden
mailing list.  This reaches hundreds of netCDF users, and someone else
may know of some work in this area of which I'm not aware.
