There was one which is deprecated, but the correct way to do this is  
with the radar-find cgi, this gives you full control over the  
display. In fact the deprecated cgi simply called the radar-find cgi  
with a fixed set of parameters that worked for whatever cell phone I  
had at the time. The parameters are documented at


For example, here is the URL I use on the iPhone, it is magnified  
because the iPhone starts with it scaled to fit the screen, the zoom  
factor allows me to zoom in on the part I want and makes it easier to  
see the full details:


I had to add the amx radar to the end, because the Key West radar is  
down at the moment, but if you do not specify a radar call it will  
automatically use the closest.

If you have an old fashioned cell phone with a small display and no  
zoom (be ashamed you Luddites ;-), you might want something like:


Remember the offset is from the center to the edge, so 50's give a  
100x100 pixel image. Zoom works <1, so if you wanted to see more area  
in those 100 pixels, you can do this:
