A really cheap/cheat way of doing it would have your gps record every X seconds (rather than X distance, or other varying amount). Display a map with a marker, and make it move to the next location(taken from the trimmed gpx file) every X seconds. Then you have some way of triggering your map animation to start and your movie to start at the same time with one button. I number of problems can be found in this (such as the movie player being slow to play, or the user pausing the movie), but as I said, it is a cheat method. -- Gregory [email protected] http://www.livingwithdragons.com
