Julie Darnell--
You can check Maurizio's theory by looking at the range of coordinates
and redefining them as necessary, e.g.:
use uscoordinates2
su _X
local xmax=r(max)
local xmin=r(min)
su _Y
local ymax=r(max)
local ymin=r(min)

use us-stateoutline.dta
su _X
replace _X=(_X-r(min))*(`xmax'-`xmin')/(r(max)-r(min))+`xmin'
su _Y
replace _Y=(_Y-r(min))*(`ymax'-`ymin')/(r(max)-r(min))+`ymin'
save rev-stateoutline

I tried to apply a similar syntax to the example datasets:

use Italy-RegionsData.dta
spmap relig1 using Italy-RegionsCoordinates.dta, id(id) ndfc(white)
fc(Blues) ocolor(gs12 ..)  ///
      polygon(data(Italy-OutlineCoordinates.dta))

and I seem to get what you're looking for.
Given your description, it sounds like your maps are expressed in different
coordinate systems, so that they cannot be properly combined. Just a guess,
anyway.
Best,
Maurizio
