Ok.
It's about using Google Map to track ships and planes. We people are not familiar with ships or planes trajectories. But we fly a lot. And our products are being shipped a lot. So my idea, which will benefit more people than Captains is to reveal this to public.
The only example application I've found is this one:

I really need some advice, because when I said I like knowledge I mean I don't know what systems ships are using for tracking, if Google will accept such project, and how I'm going to make money with it.
thanks
