Hi, Normally the only thing to do is to use an "SRS" parameter, something like:
var layer = new OpenLayers.Layer.WMS( 'YOUR_LAYER_NAME', "http://YOUR_WMS_SERVER', { layers: 'YOUR_LAYER', transparent: true, format: 'image/png', SRS: 'EPSG:3857', SLD: 'http://YOUR_SLD_ADDRESS' }, { isBaseLayer: false, singleTile: true, opacity: 0.8, visibility: false } )I don't know which WMS server you use, but if it's Mapserver don't forget to add the supported projections in the WEB METADATA section, something like "wms_srs" "EPSG:4326 EPSG:3857", otherwise it will not work.
For example:
WEB
IMAGEPATH "/tmp/"
IMAGEURL "/tmp/"
METADATA
"ows_enable_request" "*"
#######
# WMS #
#######
"wms_title" "my WMS server"
"wms_onlineresource"
"http://my/wms/address?map=/path/to/mapfile.map&";
"wms_srs" "EPSG:4326 EPSG:3857"
END
END

How do I request a specific SRS when creating a wms layer?

The following WMS feed is served both as EPSG:4326 and EPSG:900913 (have a look at the WMS link in the table): http://iridl.ldeo.columbia.edu/SOURCES/.USGS/.LandDAAC/.MODIS/.1km/.8day/.version_005/.Aqua/.EAF/.Night/.LST/X+Y+fig-+colors+coasts+-fig+//LST/255./330./plotrange//T/3118./plotvalue/Y/1.5405659E-04/39.99557/plotrange//plotborder+72+psdef//plotaxislength+432+psdef//XOVY+null+psdef/ When I do this: var wms = new OpenLayers.Layer.WMS( "IRI", "http://iridl.ldeo.columbia.edu/SOURCES/.USGS/.LandDAAC/.MODIS/.1km/.8day/.version_005/.Aqua/.EAF/.Night/.LST/X+Y+fig-+colors+coasts+-fig+//LST/255./330./plotrange//T/3118./plotvalue/Y/1.5405659E-04/39.99557/plotrange//plotborder+72+psdef//plotaxislength+432+psdef//XOVY+null+psdef/wms.xml";, { layers: "USGS LandDAAC MODIS 1km 8day version_005 Aqua EAF Night LST", } ); ..I get a 4326 base layer. But I want it to work with my 900913 map so I add to the params object: { layers: "USGS LandDAAC MODIS 1km 8day version_005 Aqua EAF Night LST", srs: "EPSG:900913", bbox: "-2000000,1,6900000,4400000" } but it does not work. The getFullRequestString() returns a string with the correct BBOX, but the SRS it still 4326. To me it looks like only the first tile has 900913 and the rest (twenty-something) have 4326. What am I doing wrong? Jan _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
