[mapserver-users] WMS Overlay shift

[Frank Broniewski]

Hello list,

I am debugging a problem with my WMS server. I am serving administrational 
boundaries in a national reference system for use in different applications.

Just yesterday I noticed a shift of the WMS layer to the east when I overlay 
the WMS layer with the original shapefile in ArcGIS. The shift is approx. 29m 
and I have no clue where to start looking for a solution.

There is only one projection in the mapfile, and I set the view in ArcGis to 
the same projection. I checked the projection definition in ArcGis already to 
see if there is some mismatch but I couldn't find any. So I am rather clueless 
where to start looking for the reason of the shift.

I checked also in OpenJump to see wether this is an ESRI effect, but there is 
the same shift in OpenJump

Any hints are welcome ...

Frank
