[Qgis-user] After upgrade none of the TIFF imagery is visible

[Nicolas Cadieux]

Did someone help you on this? 
 I am Not sure why the raster would not show up?  Right click a layer ad select zoom to layer extant.  Can you see it?m if not, click the layer property and change the way the raster is rendered (min max).  If it does not work, send an old project file with a few of the rasters. I will look at them. 
Grass, saga and the rest are other Gis programs.  Qgis lacks some analysis tools so rather than making everything from scratch, they make ports to other programs.  Don't remove then.  One day you will be stuck with a problem and see that Grass or SAGA has a good algorithm!

	I was using QGIS 1.8 and upgraded to 2.8.1.  When I open an old Project, 
the image layers are present in the list on the left, but none of the 
imagery is visible on the map.  Not sure how to bring the imagery back.
Also, I'm overwhelmed by all of the programs that were installed: Grass, 
Desktop, Browser, SAGA.  Is there a brief description explaining which 
to use under various circumstances?
Thanks!
Jon
