Hi Peter,
NAD83 is a datum. OpenMap assumes the WGS84 datum is being used for
it's decimal degree coordinates, so if you use NAD83 coordinates,
you'll see some differences on the location of features if you try to
match them. To show things in their accurate location relative to
other objects, you'd have to convert the NAD83 coordinates to WGS84
coordinates.
