[OpenLayers-Users] Openlayers map WMS stretched by latitude

[Phil Scadden]

Couple of things. Firstly, Displayprojection is map setting, not a 
layer. It controls what will be displayed in things like the 
mousePosition control.

Secondly, doesnt matter what projection you specify for a WMS layer that 
is not the baselayer. Openlayers will generate a request to the WMS 
server in the projection of your current baselayer. You can use the NET 
tab on firebug or similar to see the request. Do a getcaps call to the 
mapserver to see whether it supports the EPSG of your base layer (which 
it sounds like is 3857).

It can be very irritating when you have two wmsservers that have 
mutually-incompatible SRS codes for the same projection. You can get 
around it with an override (did for ages on the arcgis servers before 
they got 3857). But first want a
http://yourserver?request=GetCapabilities&service=WMS to get the 
supported projections.
