[Qgis-user] QGIS Server Projection Problems

[Hung,Emma [Ontario]]

I am running Ubuntu 12.04 with qgis (2.0.1), qgis-mapserver and
libapache2-mod-fcgid packages installed using apt-get install.
I am trying to serve up data from gml files to a WMS client (I've also
tried shape files). The source is in lat/lon EPSG:4326 projection, I've
specified this same projection for the project (or at least I believe I
have). Once I save the project I then use the .qgs file as my "mapfile"
for the qgis mapserver. When I compare the output from QGIS Server and
MapServer in my WMS client I observe that the projections do not match
(note the source is the same for both), I see the same distortion
whether I use gml or shape files as a source. I'm confident that the
result from MapServer is correct because it matches the original images
from the producing software. I've attached a screen shot to this email
to illustrate the distortion, the green areas are from Map Server and
the yellow are from QGIS Server.

Here's a snippet from the destinationsrs block:
        <projections>1</projections>
        <destinationsrs>
            <spatialrefsys>
                <proj4>+proj=longlat +ellps=WGS84 +datum=WGS84
+no_defs</proj4>
                <srsid>3452</srsid>
                <srid>4326</srid>
                <authid>EPSG:4326</authid>
                <description>WGS 84</description>
                <projectionacronym>longlat</projectionacronym>
                <ellipsoidacronym>WGS84</ellipsoidacronym>
                <geographicflag>true</geographicflag>
            </spatialrefsys>
        </destinationsrs>
and here's the srs block:
            <srs>
                <spatialrefsys>
                    <proj4>+proj=longlat +ellps=WGS84 +datum=WGS84
+no_defs</proj4>
                    <srsid>3452</srsid>
                    <srid>4326</srid>
                    <authid>EPSG:4326</authid>
                    <description>WGS 84</description>
                    <projectionacronym>longlat</projectionacronym>
                    <ellipsoidacronym>WGS84</ellipsoidacronym>
                    <geographicflag>true</geographicflag>
                </spatialrefsys>
            </srs>
and the SpatialRefSys block:
       <SpatialRefSys>
            <ProjectCRSProj4String type="QString">+proj=longlat
+ellps=WGS84 +datum=WGS84 +no_defs</ProjectCRSProj4String>
            <ProjectCrs type="QString">EPSG:4326</ProjectCrs>
            <ProjectionsEnabled type="int">1</ProjectionsEnabled>
        </SpatialRefSys>

The WMS client is re-projecting to suit its needs.

Please forgive me I'm not a GIS expert my background is computer science
and I work with research meteorologists so my grasp on geographic
projections is not great, mathematically I get what needs to be done but
I'm not familiar with all the lingo for describing them.

I'd appreaciate any insight you might have on this issue. I quite like
the WYSIWYG aspect of creating the map file and would love to use the
QGIS mapserver instead of MapServer, but if I can't fix this I'll have
to settle I suppose. Thank-you!
