Rob, Anyone can correct me if I am wrong on this however I think you have to enter projection information in 3 times.
1) the projection of your map 2) the projection of your data, in this case the wms service so that mapserver knows what to reproject from. 3) the projection that you are requesting from the wms service - in the metadata section. I am doing this on some of my applications so let me know if your having trouble, otherwise if someone has a better thought let me know if I am wasting lines of code. Example: MAP ... Projection # of the Map End Projection ... .. Layer Projection # of the Source End Projection ... Metadata "wms_srs" "ESPG:27700" #projection you are requesting in WMS .... End #Metadata ...

I am trying to set up a basic Mapserver install (MS4W v3.0 Beta 4) MapServer version 5.4.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP OUTPUT=PDF OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICO NV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUP PORTS=THREADS SUPPORTS=GEOS SUPPORTS=RGBA_PNG INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE which points to a WMS service which only supports a single projection. I want to get my Mapserver to reproject that data on the fly to other projection systems, but don't seem to be doing it right! This is my mapfile MAP NAME SPIRIT STATUS ON SIZE 600 600 EXTENT 0 0 650000 1300000 UNITS METERS SHAPEPATH "temp" IMAGECOLOR 255 255 255 #FONTSET 'fontset.txt' #SYMBOLSET 'temp/examples.sym' IMAGETYPE JPEG IMAGEQUALITY 75 IMAGETYPE png OUTPUTFORMAT NAME png DRIVER "GD/PNG" MIMETYPE "image/png" IMAGEMODE rgb END IMAGETYPE jpeg OUTPUTFORMAT NAME jpeg DRIVER "GD/JPEG" MIMETYPE "image/jpeg" IMAGEMODE rgb END PROJECTION "init=epsg:27700" END WEB IMAGEPATH "c:\temp\" METADATA WMS_TITLE "WMS Server" WMS_ABSTRACT "WMS Server."

Any help gratefully accepted!
