Is this related to your earlier post? http://groups.google.com/group/google-maps-api/browse_thread/thread/c738673df8a6ff36# You might look at getting directions between the change points, and drawing the directions route line yourself using the line-width and colour you need. If you draw the line yourself you are within the Terms, although you will need to be careful of the number and rate of requests you make. I have an example here of getting multiple directions: http://www.acleach.me.uk/gmaps/multi-distance.htm (that starts from a central point, but demonstrates the rate-limiting). As well as the risk of running into limits, using directions also runs the risk that if your change-points are not close enough together, Google's route between them may not be what you expect. The best method is to maintain your own database and create custom tiles you can overlay on the map. -- You received this message because you are subscribed to the Google Groups "Google Maps API V2" group.
