[mapserver-dev] testing CONNECTIONTYPE UNION

[Jeff McKenna]

Hello all,

Just doing some tests for the docs, and I notice the union layer will 
only reproject its source layers if the union layer (not the source 
layer) has a PROJECTION object defined (I would have thought that if the 
union layer was in the same projection as the MAP object's projection 
(yes an old trick), then I wouldn't need a projection object defined in 
the union layer).  I personally think that the union logic should be: if 
no projection object in union layer, look for map-level projection 
object, and use that for reprojection.

Thoughts?
