EPSG code for...

[Christopher R. Thorne]

Yes I used these projections where

26911 NAD 83 is the projection of the mapfile and where NAD27 <26711> is 
being reprojected.

See first attached image to see how messed up the Nad27 layer gets.

If I don't define projection you can see the a shift between the line 
layer and the solid polygon layers.

Comments/suggestions??

Thanks
Chris
