AW: [UMN_MAPSERVER-USERS] How to make Moving Symbols using MapScript

[Klingseisen Bernhard]

Hi,
 
You should also consider SVG as an alternative. I've once done some testing for a taxi tracking system (unfortunately not available at the moment). Examples e.g for a moving vehicle on a bus rout can be found at: www.carto.net. 
 
Regards

        Vdharan,
	
        Not that I know of. I would be a great extension to Rosa or to Mapplet.
        You might want to check on the Rosa list and see if anyone has done
        this. If you get something like this working post a note back here
        because I would be interested and I'm sure some others would be also.
