Which projection should I use to get my WMS service to work?

Question

All of my shapefiles have exactly the same WKT. Using http://prj2epsg.org I have verified that EPSG:3059 has the same parameters as WKT definition of my shapefiles, so I'm using 3059 in my mapfile.

I want to know what changes I must make in my mapfile for my WMS service to work.

What I have tried:

I thought maybe epsg:3059 is not supported by my mapserver version 6.0.3. I checked file C:\MS4W\ms4w\proj\nad\epsg and 3059 is listed there. Still, I tried to convert the shapefile to different epsg, for example, 4326 and 3857. No success. I also tried setting up the newest stable Mapserver version 6.4.1. No success.

When I send GetCapabilities request...

http://localhost:1025/cgi-bin/mapserv.exe
?map=C:\MS4W\ms4w\Apache\htdocs\gis\mapfile2.map
&SERVICE=WMS&VERSION=1.1.1%20
&REQUEST=GetCapabilities

I get a response XML document with no errors and warnings.

When I send a GetMap request...

http://localhost:1025/cgi-bin/mapserv.exe
?map=C:\MS4W\ms4w\Apache\htdocs\gis\mapfile2.map
&SERVICE=WMS
&VERSION=1.1.1%20

&WIDTH=800
&HEIGHT=600%20
&FORMAT=image/png

I get this message as response:

...
msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be valid for all requested layers.
...

If I access mapfile via browser, I can see the layer displayed correctly:

I don't know why you have set EPSG:42304 as projection. This value is not defined in the SRS list or the EPSG registry.

EPSG:3059 has the same parameters as your WKT definition. You have to add it to your list of wms_srs to allow requests in that srs.

EDIT

Looking at your WMS request: Why do you send &SRS=EPSG:3059%20 ? Can you try without %20?

I have set EPSG:3059 to be both projection and SRS. Is that correct? Error message about SRS remains.

I wasn't able to locate a source/author for 42304 other than a reference to a 'Chameleon' demo, but I did see several definitions that describe it as "NAD83 LCC for Canada", so that could be part of the problem.

I have had no success with using EPSG:3059. Question is updated with details.

You are right again, you should add that to your answer.

&SRS=EPSG:3059%20

That %20 is an escaped white space. You need to get the white space out of the query string.

When I pasted your WKT into http://prj2epsg.org - it suggested a number of possible codes one of which is epsg:3059 another possible one is EPSG:25884 TM Baltic93.

But it looks like your problem is to do with your MapServer set up not the projection of the shapefile.

EPSG:25884 has +y_0=0 which might lead to wrong placement.

I switched to using epsg:3059 as both projection and SRS. Is that correct? Added a fragment of my mapfile to my question, see edit #2. I still get the same error about invalid SRS. And thank you for the useful link!

Couple of suggestions: It would not harm to add projection block also to LAYER as

 PROJECTION    
 "init=epsg:3059"    
 END

Do you perhaps have other layers in you mapfile set to STATUS DEFAULT and missing some projection data? Could you show your whole mapfile, the one you pasted is probably a shortened version? By looking at the GetCapabilities it looks like you have configured the layer lat_rob_region to belong under group layer karte

I tried your mapfile modified slightly to suit my own shapefile and it did work for me so there should not be anything fundamentally wrong with it.
