sorry!, I meant "4326" instead of "4322" =)

Are you using Mapserver? if so, you should read this one: http://mapserver.org/ogc/wfs_server.html, these instructions are useful for WFS layers, but WMS is a bit more problematic, try this one also: http://mapserver.org/ogc/wms_server.html. I think with both of them you will start understanding where the problem is, that it is basically adding the "wms_srs" flag (if using Mapserver) and adding the right projections. If your raster is in UTM, you have to play a bit, probably assigning the right UTM SRID (check for getting ideas: http://stackoverflow.com/questions/1541202/how-do-you-know-what-srid-to-use-for-a-shp-file) plus the 4322 as you already did (or as it appears in the WMS web I put above). Hope this helps!, cheers Date: Thu, 24 May 2012 17:12:27 -0400 From: [email protected] To: [email protected] CC: [email protected] Subject: Re: [OpenLayers-Users] wms layer over openstreet base map Hola Gery, That does help and I have been able to narrow the problem down a bit more. I think this has to do w/ the fact that I am attempting to load a wms layer and there isn't an entry for the item in epsg file. I gathered this from the following page I have now added the epsg for 900913 but I am still having an issue. I was able to get an error back from the wms server which is: <?xml version='1.0' encoding="ISO-8859-1" standalone="no" ?> <!DOCTYPE ServiceExceptionReport SYSTEM "http://schemas.opengis.net/wms/1.1.1/exception_1_1_1.dtd";> <ServiceExceptionReport version="1.1.1"> <ServiceException code="InvalidSRS"> msWMSLoadGetMapParams(): WMS server error. Invalid SRS given : SRS must be valid for all requested layers. </ServiceException> </ServiceExceptionReport> Thanks, Derek On 5/24/2012 1:46 PM, Gery . wrote: Hello, I think you're right, projection has something to do there, this link may help you: http://blog.sonxurxo.com/2011/04/28/tutorial-de-openlayers-ii-capas-de-google/ There is a lot of stuff about google maps and openlayers and projection, just google them.
