The main problem could be that your layers are in different CRS. I assume that 
you want to use lat lon coordinates ("they should be in the range of (-87, 
41)"). Because you can not have millions of degrees, it is pretty sure that the 
layers that display coordinates in the millions could be a CRS that defines its 
measuring units in meters or feets. For vector layers (and assuming a format 
that can store projection information), select the layer , right click, choose 
properties and go to the general tab. There you must be able to see the 
projection information. For raster layers go to rater menu,  choose 
Miscellaneous and select info. Choose your raster and you must be able to see 
the projection information there. 

I like to have all my layers in the same CRS, some people also likes to use the 
"on the fly CRS transformation" capability of QGIS . Try in Settings, project 
settings and go to the CRS tab, Choose "enable on the  fly CRS transformation", 
then load some layers. One  thing is for sure, you must know the crs of each of 
your layers before starting to work with them.

Hope it helps

Subject: [Qgis-user] problems with layers from one source

Hello (again!) 
 
I'm having trouble with all the layers I download from one particular source. 
These layers don't show up in the same place as any others of the same area, 
including those I've geocoded myself. The coordinates shown at the bottom of 
the screen for these are HUGE - they should be in the range of (-87, 41) but 
they're in the millions. I've made sure all layers are in the correct CRS and 
done everything else I can think of. Does anyone have any tips or ideas? Thank 
you!


Caroline
