Hi

Sorry if I posted this in the wrong place!
I have an idea for an application using GPS. I haven't been able to find this done by anyone else, and I think other people would find it useful aswell.
My idea is, I would like to be able to log co-ordinates of a journey using GPS, then display them later, overlaid as a "trail" on a map - preferably one of the web maps, like googlemaps or multimap. I know the logging would be possible, but I have no idea whether overlaying the trail on someone elses map is possible!
Any ideas anyone?
