Hawaii uses their own Old hawaiian Datum - it you have ArcView 8x the conve=
rtion routines are in there. Also remeber that Hawaii state plane and the =
general old hawaiian will give you difference as well.

Subject: GISList: Hawaii GIS
Hi List:
We are having some difficulty with out Hawaii GIS. I received USGS
DRG's that are in UTM NAD27. Overlaying our Hawaii roads coverage
reveals a uniform offset in the DRG data of over 100 meters. We have
confidence in our road data because of field validation with GPS. I
suspect that the problem is perhaps unique to Hawaii. Does this
problem sound familiar to anyone working with Hawaii data?
Thanks in advance,
Thomas
