Hi Dimitrios, thanks for providing the link to your application. It might be useful for one of my future projects. As to your question: there might be several options. It depends on your environment. Some SVG viewers support sockets, but then you might run into firewall problems. One easy way to do it is to encode the GPS information in an XML fragment and load that fragment with the getURL() method. There is a paper available at svg.open that discusses that: http://www.svgopen.org/2002/papers/bennett__gps_tracking_with_svg/index.html On receiving the data you can parse the XML fragment extract the data you need or integrate it into your DOM-tree. You could use a timer to regularly call getURL().
