With its integrated GPS chip, your iPhone will act as data logger to record your track as an NMEA file, compatible with Kinomap.
If you own a 3GS iPhone, use the other app: Kinomap Maker whiwh is also free and allow the recording of the video and direct upload to geolocated website Kinomap!

Start recording and automatically, your location is recorded second by second (with your speed and altitude).
Then you'll be able to see the information on this track and its visualization on a map.
Finally, you can export your NMEA file by email.

Note: the accuracy of GPS depends on many factors (open field or urban units near the iPhone, waiting at the start of the video, etc.). We recommend that you wait for the green signal for the GPS before you start recording.
