I'm trying to develop a web based routing system where you put your start and end locations, and along the way I want to show points of interest. The problem is that I can't include waypoints unless I know the route the map is planning to take them. The waypoints need to be on the roads themselves. So I don't know how this would be done, but if like every 3 miles of travel I can get a lat/long that'd be great. Is the API capable of doing this?
For my second incarnation of this, I'd like the above, but have heatmaps of the waypoints as long as they're within X feet of the waypoint.
Not looking for code, but would take examples, articles, how-to's, or just how to access the api which I can then massage and output the html I need.
Thanks, Tuc
