shrug-l: Data Drift in GeoDataBases

[Johnson, Jay]

I just converted a coverage of roads to a shapefile using ArcGIS Toolbox and
found the same coordinate drift problem, so the issue apparently is NOT
restricted to geodatabases.  The same coverage to shapefile conversion done
in ArcView 3.2 does not exhibit coordinate creep.

The age old problem of data drift shouldn't occur when you are simply
copying a dataset from one format to another (or should it?).  It doesn't
happen when you convert a coverage to shape file (because you can still use
the shape file to select features from the coverage and vice versa) why
should it happen when you convert either cov or shape to a GDB feature
class?

I'm just hoping that there's something I'm missing regarding this whole
thing, but I can't for the life of me figure out what it is....
