I couldn't find OpenLayers.Layer.OSM in the API docs, but the coordinates on your sample look like they're in 'spherical mercator', which is common for WMS providers like Google, Yahoo, etc. http://docs.openlayers.org/library/spherical_mercator.html says that OSM is indeed spherical mercator. So, I think you're getting x & y values in the coordinate system of your base layer. I think the values are actually a number of meters north & east of 0. You can translate that to EPSG:4326 (lat/lon) using a function described in this page http://dev.openlayers.org/releases/OpenLayers-2.9.1/doc/apidocs/files/OpenLayers/Layer/SphericalMercator-js.html Also take a look at the re-projection examples on the spherical_mercator.html page I linked to above. alex _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
