Ah! Indeed, I already thought the solution would be trivial! Thanks, this solved my problem.
As I am new to OpenLayers, I started off here: http://docs.openlayers.org/ Too bad I couldn't find any hints on OL's defaulting when it comes to projection, units, extents etc. In fact, I expect many newbies wanting to deviate from the default EPSG:4326... May I suggest to insert the below lines of code on this page: http://docs.openlayers.org/library/introduction.html //set always mapOptions, if you use a projection other than EPSG:4326 mapOptions = { projection: new OpenLayers.Projection("EPSG:28992"), units: "m", numZoomLevels: 18, maxResolution: 5, maxExtent: new OpenLayers.Bounds(131110,447700,131830,448310) }; map = new OpenLayers.Map('map', mapOptions); Ciao, Rob 2011/4/22 Arnd Wippermann <[email protected]> > hi, > > if you declare your map without options, then OL takes the default (see > Map.js): > > projection: "EPSG:4326", > units: 'degrees', > maxResolution: 1.40625, > maxExtent: new OpenLayers.Bounds(-180,-90,180,90), > But it seems, when you declare a projection in your baselayer, then this > projection overwrites the map projection and is used for the SRS parameter > of the WMS request.
