[OpenLayers-Users] WMS layer with different SRS than basemap

[Dejung Gewissler]

Hi All-

I've searched on Nabble for the answer to this to no avail. I know you 
all are busy with the release cycle (!kudos to all that are involved!), 
but I was hoping someone has an easy answer for this problem.

I've got some WMS services coming from IMS or ArcGIS servers and some 
others coming from GeoServer. Unfortunately ESRI identifies the NJ State 
Plane (us feet) coordinate system as EPSG:102711 and GeoServer uses 
EPSG:3432. ESRI doesn't have a EPSG:3432 and GeoServer doesn't have a 
EPSG:102711!!! I understand that OpenLayers doesn't support raster 
reprojection because it would be nearly impossible to do in a browser, 
etc. My images, however, are fundamentally of the same projection, 
albeit with a different SRS identifier. I just need them laid on top of 
each other.

I define my map with options {... projection: 'EPSG:102711' ...} and my 
WMS overlays with {... srs: 'EPSG:3432' ...}. The WMS overlays are 
nonetheless being sent with SRS=EPSG:102711. It seems that OL ignores 
the passed-in srs in the layer constructor and defaults to whatever the 
baselayer's projection is. That makes sense in stopping the raster 
reprojection train, but poses a problem in my situation. Is there a way 
to force the SRS change of a WMS overlay?

Thanks,
Dejung
