Ron,
I don't know NAVD88 but I suspect this is a vertical datum ("VD", see
the reply of Paul earlier). The point is, FME does not support vertical
transformation as far as I know. The Reprojector only transforms 2
dimensions. Therefore there is no need to define the vertical datum. If
you need to transform the VD (as is usual when you get raw LIDAR data
since those usually are provided in WGS-84 / UTM with ellipsoidal
heights, thus you will have to transform them to your working height
system; but that is rarely the case when you get finally processed
LIDAR data, e.g. grid data) then you would have to use different
software. The 3D case is not that commonly used, thus most GIS software
does not support it.
If the VD you need to use is different from the VD the LIDAR data are
provided in and you want to transform it you will also have to use
different software. We use - beside other software - SKI Pro (C) from
Leica Geosystems for that purpose.
I hope this helps.
