MapServer does not support WMS

[olt]

The MapServer itasca demo on the LiveDVD does not support WMS. It is missing a projection definition and the ows_enable_request settings. I reported that two month ago ​http://lists.osgeo.org/pipermail/live-demo/2011-June/003504.html

It is not possible to use the demo in uDig/QGIS/MapProxy/etc. The MapServer demo/quick guide works, but it should also support WMS since we (OSGeo) advocate open standards.

quote the June email:

Hi,

I'm creating an example configuration for MapProxy for the LiveDVD and I
found out that the Itasca Demo from Mapserver is not configured properly.
I get the following error if I make WMS requests:

<!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1">
<ServiceException code="InvalidSRS">
msWMSLoadGetMapParams(): WMS server error. Cannot set new SRS on a map
 that doesn&#39;t have any projection set. Please make sure your mapfile
 has a projection defined at the top level.
</ServiceException>
</ServiceExceptionReport>

It also doesn't work in uDig for example. It works fine if I uncomment the
PROJECTION part in the itasca.map file. Can someone update the example for
the next LiveDVD release? (and add a author/maintainer comment to the
install_mapserver.sh :)

Oliver

the source of the data is stored in gisvm/trunk/app-data/mapserver/workshop/mapserver-itasca-ms60.zip

so to fix it we can just unzip, edit, and rezip that.

here is a possible patch, what do you think?

n.b. the proj4 "+north" term doesn't exist/is a no-op, only utm "+south" counts. I assume the "OR" was comments not code. I don't know if it matters, but also note the specified proj terms do not set the datum (NAD83) while the EPSG version does.

Plus the ows_enable_request stuff that is new in 6.0.

can you prepare a patch? I don't know mapserver well enough to know if I'm screwing it up or not.

thanks, Hamish

WMS works with that patch. Tested with MapProxy on 5.0rc1.
