Hi, I wouldn't restrict it to sphericalmercatoralias. I use a similiar approach to add WMS Server, which use a different EPSG code than my map, but describe the same projection.
Why not use options.projection to request the WMS in this projection? OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams,altUrl) { try{ var projectionCode = typeof this.options.projection == 'undefined' ? this.map.getProjection() : this.options.projection; }catch(err){ var projectionCode=this.map.getProjection(); } var value = (projectionCode == "none") ? null : projectionCode if (parseFloat(this.params.VERSION) >= 1.3) { this.params.CRS = value; } else { this.params.SRS = value; } return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this, arguments); }, Arnd -----Ursprüngliche Nachricht----- Von: users-boun...@openlayers.org [mailto:users-boun...@openlayers.org] Im Auftrag von Anne Blankert Gesendet: Sonntag, 25.

The following code should do better (Version >= 1.3 not yet tested): // override OpenLayers.WMS.getFullRequestString class member function OpenLayers.Layer.WMS.prototype.getFullRequestString = function(newParams, altUrl) { var projectionCode = this.map.getProjection(); var value = (projectionCode == "none") ? null : projectionCode if (this.options.sphericalmercatoralias) { if(value == 'EPSG:900913' || value == 'EPSG:102113' || value == 'EPSG:3857') { value = this.options.sphericalmercatoralias; } } if (parseFloat(this.params.VERSION) >= 1.3) { this.params.CRS = value; } else { this.params.SRS = value; } return OpenLayers.Layer.Grid.prototype.getFullRequestString.apply(this, arguments); } After this override, you can set a new layeroption 'sphericalmercatoralias' to tell OpenLayers to use that instead of the default as follows: layer = new OpenLayers.Layer.WMS(title, url, {layers: layernames}, {sphericalmercatoralias: "EPSG:102113"}); -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/SphericalMercator-and-SRS-aliases-eps g-900913-epsg-3857-epsg-3785-epsg-102113-tp5311417p5334827.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
