[mapserver-users] WMS layer is not shown in right projection

Fri Sep 19 05:12:10 PDT 2008

Hi list,
I have a problem according to the projection of my layers. I have set up the foss-gis-suite and use OpenLayers as client. I have configured MapServer as WMS-Server.

If I request a layer (using EPSG-Code 31468 [Gauss Kruger zone 4]) via OpenLayers.Layer.MapServer the response is OK but if I try this with the OpenLayers.Layer.WMS layer I don't get the map. I have tested the EPSG-Code 4326 and the map shows up (but stretched).

Why can't I use the same projection for both layers or where is the failure?

OpenLayers-Code:

    		var map = new OpenLayers.Map("map",{
    			units: 'm',
    			projection: 'epsg:4326'
		});

    		var mapserv = new OpenLayers.Layer.MapServer.Untiled("Local MapServer",

    		map.addControl(new OpenLayers.Control.MouseDefaults());
