You can simplify polylines using the Ramer-Douglas-Peucker algorithm, which discards vertices that are not needed for your zoom level. The API does this in the server for driving directions, and in the browser for other polylines.
For efficiency the API will not draw offscreen polylines. Are you generally concerned about latency or have you observed slow performance on a mobile?

This is because I don't need the amount of detail when I'm zoomed out and am serving this as a mobile friendly site so would like to use as little processes as possible. thing 2) I have many different polylines (I call them routes), and would like to only draw a polyline based on my maps "bounds". Is there a way to only draw a line this way? or is this something that I need to do by checking the coords that go into the creation of my polylines agents some "bounds" objects etc. Thanks so much! - The Net Duck -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
