I have upgraded to 2.02 and now I can see the tiff in my map.  however,
I can only see the tiff in my map when the coordinate system is the same
as the coordinate system in the tiff (regardless of overrides).  Any
ideas?

I did have a coordinate system override specified at first.  It was the
same coordinate system as my map (WAHP-NF), but when I looked at it in
the layer preview, the scale was 1:4.65.  Seeing as the TIFF covers the
entire Puget Sound in Washington State, I knew something was up.  So I
didn't specify an override, and I create a new map with the same
coordinate system as the tiff.  When I look at the tiff in the layer
preview sans override, the scale is 1:1698729.00 (which is more like
it).

However in my map with the same coordinate system, I see nothing.

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?

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?

 

Thanks.
