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.

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. -Mark Pendergraft
