Great thanks for the prompt reply Marcello, and apologies for the lack
of clarity.

Let me rephrase the problem. A "point" means geographical coordinate
<lat,long> here.
- Lets describe a Path as a set of say 50 points (which the GPS has
collected over a few minutes in a moving vehicle)
- Lets specify a point P (which is the gate of my house)
Q: is there a Google Maps API call which can tell if P lies on the
Path (i.e if the vehicle passed the road infront of my house's gate)

Note that there are no visuals involved here, i.e I dont want my users
to see a map.

Also, you may say that I can simply calculate the distance of P from
each point in the Path. Suppose it turns out that the point closet to
P in the Path is 300m away. Now, without looking at any map, how can I
tell if there is no other road between P and the Path?

In the code, the call may look like:

boolean isOnPath(Point[] path, Point aPoint)

Hope this makes it clear.
