hi,<br>I guess you need to transform the coords from 900913 system to 4326, don't you?<br><br>I am not an expert but I think you just need to use the transform function.<br>firt get a var called yourcoords (in the example I wrote) with the coordenate you want to transform.<br>
<br>Then do the transform.. like this.<br><br>newcoords = yourcoords.transform(new OpenLayers.Projection("EPSG:900913"),new OpenLayers.Projection("4326"))<br><br>900913 and 4326 are defined (I think) in Openlayers. If this is not working then you can try to do the transform with the proj4js api. If you do, read first this. <a href="http://trac.osgeo.org/proj4js/wiki/UserGuide">http://trac.osgeo.org/proj4js/wiki/UserGuide</a><br>

Hi all,<br>I have been fiddling with this way too long already, so I ask:<br><br>After changing the Click Event Example a bit I am getting coordinates like this:<br>
<br>
5383153.349692758 1323087.0961396247<br><br> Click Event Example: <a href="http://www.openlayers.org/dev/examples/click.html" target="_blank">http://www.openlayers.org/dev/examples/click.html</a><br><br>However I need them like this:<br>
<pre>43.468243 11.880172<br><br>Btw. same format as the coordinates in the "data.txt".<br><br>I think "All I DID" is changing from WMS to OSM Layers?<br>How to automatically convert?<br><br>Thanks.<br>
