Hi Mark
Thanks for the reply. But I am already putting the projection
information in three places arent I?
MAP
PROJECTION
init=epsg:27700
END
WEB
METADATA
http://localhost/cgi-bin/mapserv.exe?map=example.map;
WMS_SRS EPSG:27700 ESPG:4326
END
END
LAYER
NAME layer
CONNECTION http://externalwmshost/;
CONNECTIONTYPE WMS
METADATA
wms_srs EPSG:27700
END
END
The external WMS only supports 27700 - thats why I want to reproject
in my mapserver instance.
Any other clues?
Thanks
Rob

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
...
End #layer

Hi
I'm obviously having Friday afternoon blindness, as I can't see what I
am doing wrong! 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

but when I make a WMS request against it
http://localhost/cgi-bin/mapserv.exe?map=example.maprequest=getmapservice=w
mslayers=layerbbox=53.5,1.4,53.51,1.41width=400height=400version=1.1.1s

I'm guessing I'm missing something simple, but I don't know what it
is. Any help gratefully accepted!
Thanks
