Did you specify a coordinate system override on your Data connection so that when you add the layer to the map it knows what CS it's in?

Subject: [mapguide-users] Tiffs and MGOS 2.01

I'm having trouble with TIFF's in MGOS 2.01.  I'm using Mapguide Studio 2009 and the GDAL provider.  I can create a data resource from a directory containing 4 tiffs (downloaded from USGS National Map - NED Imagery).  And I'm able to create a layer, and view the tiff data in the layer preview.  Everything is fine until I add it into my map.  It doesn't show up at all.  I have even made another map with just the tiff layer, and zoomed way out.  Nothing.  I have tried different coordinate systems, and I'm currently using the LL83 (which is the same as the tiff coordinate system) and I've even plugged in the lat/longs from the tiff's lower/upper corners into the map.  Am I missing something here?
