Hi all, I'm developing a project for Area Monitoring, where I have to detect a person deviating from a route (pre defined). I donno how this can be done, I have searched the Wiki and came up with a Qt code to do this, but it requires the lat/lon coordinates for each certain distance in the route, say for 100 meters.

I've asked about this in Google maps forums and DiBos, but didn't get enough answer. Has anyone implemented this, if yes then please help me to do this.
