I am developing a VB application which calculates a route.
If I know the current lat / long of a vehicle can I find the following
1. Has the vehicle left the route?
2. If on the route, what segment of the route is the vehicle currently on?
Thanks
Stew
Answers:
This would be very difficult to do programmatically. From the location associated with each segment on the route you can get the lat/lon of the center of the segment, but there is no simple way that I know of to determine whether any arbitrary lat/lon is within a speficied distance of the route.

It is easy to find out how far from the route a location is
objRoute.DistanceTo( objLoc )
If anyone knows how to do the 2nd part I would like to know.
