How to make Moving Symbols using MapScript

[Stephen Woodbridge]

You should be able to do this is with a Java applet or a Flash
application. And you might be able to do it with xhtml and javascript.

The problem is you need to decide whether the application is going to
get its new data by push from the server or by polling the server for
updates. Since the map is not changing except when you pan or zoom it I
would separate the map image from the vehicles being tracked so your
client side application can request map changes based on the user input
and that you get a list of vehicles and their locations as a separate
stream of data from the server, then you Java, Flash, whatever to draw
the vehicles on top of the map. make the vehicle update a separate
thread and your all done.
