AW: AW: [mapserver-users] Mapserver Projection Errors

Thu Oct 20 08:04:31 EDT 2011

I can trigger the message be a leading space. Replacing the original config:

   PROJECTION
       'init=epsg:31468'
   END

by the equivalent string from the epsg definition file:

 PROJECTION
   "+proj=tmerc +lat_0=0 +lon_0=12 +k=1 +x_0=4500000 +y_0=0 +ellps=bessel +datum=potsdam +units=m +no_defs"
 END

all works well, but with a leading space:

 PROJECTION
   " +proj=tmerc +lat_0=0 +lon_0=12 +k=1 +x_0=4500000 +y_0=0 +ellps=bessel +datum=potsdam +units=m +no_defs"
 END

it results in the mentioned error:

$ /usr/lib/cgi-bin/ms6 QUERY_STRING="map=/data/Hohlraumkarte/Hohlraumkarte.map&service=WMS&request=GetCapabilities" 
Content-type: text/html

<HTML>
<HEAD><TITLE>MapServer Message</TITLE></HEAD>

<BODY BGCOLOR="#FFFFFF">
msProcessProjection(): Projection library error. projection not named
</BODY></HTML>

So I guess your script doesn't properly generate the PROJECTION block...
