Offhand, if you're using the epsg file rather than definition your own projections by hand, the NAD83 definitions are in meters, not feet. Am I right?

Have three main data projections - NAD27 state plane, florida (feet),
NAD83 state plane, florida (feet), and UTM 17N (meters).  I set the
projection object at the top of mapfile to UTM 17N (meters).

Problem - Only the NAD83 and UTM data layers are visible. Map extents are set to UTM meters. If however, I change the map extents to state plane
feet and change the projection object to NAD 27 state plane, florida -
only the NAD 27 data layers show.

Any ideas why the NAD27 state plane layers don't show but the NAD83 layers
do?

Thanks....Rob
