EPSG code for...

[Dean C. Mikkelsen]

Hi Chris,

It may be a directory problem, MapServer is not reading the CONUS or
NAD27/NAD83 files correctly in the proj directory.

Are you using the MS4W or a later version of MapServer?

Cheers,
Dean

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
