Speaking of which,

how can I track myself using a mobile phone ?

A simple one tile google earth image would do just nicely.

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

100x100 pixel image. Zoom works <1, so if you wanted to see more area
in those 100 pixels, you can do this:
