[Qgis-user] problems with layers from one source

[Gerardo Jimenez]

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

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!
