[Mapserver-users] Raster layers are all gray

[Dan Harris]

Thanks very much for your responses!

Yes, you're right.  It is a Terraserver image.  However, the original 
world file was in UTM coordinates but everything else in my map is based 
on DD.  So I converted the coordinates in the world file to DD.  When I 
left them in UTM, the image didn't appear on the map anywhere, but after 
converting to DD, I saw *something* at least!  So I thought I was on the 
right track.

So if I can't mix the two, how can I remedy this?  The map file UNITS is 
DD as are all my layers and points.  Do I need to do something else to 
the world file to tell it to register as DD or do I have to get a 
different image from another source?

Thanks again for your help, I'm still a newbie with rasters.

But the last two lines are certainly not UTM coordinates and appear to be decimal degrees of latitude and longitude.  You can't mix the two, and you need to correct your world file.
