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

<p class=MsoNormal><span style='font-size:14.0pt'>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?<o:p></o:p></span></p>
