Hi Andy, A bit of looking at the code on the mappa mercia site shows this:
var gritting_routes = new OpenLayers.Layer.XYZ( "Gritting Routes", " http://mappa-mercia.org/tiles/gritting-overlay/${z}/${x}/${y}.png";, { "isBaseLayer": false, "sphericalMercator": true }); Which is something that can be used with OpenLayers, a javascript library, that the mappa mercia site uses. However this is effectively pointing people to the mappa-mercia hosted website and that may not be welocme if there is a sudden surge. I am sure people on this list will have an opinion on that. In terms of embedding the map easily on a wordpress blog, or the such like I have not had a look at the OSM plug ins for wordpress and whether they allow you to put addiitonal overlays over the base map (and also whether you can tone down the base map to highlight the gritting routes) without getting yourr hands dirty with code. Cheers, Stu
