The deepening of the colour is doable: if you use partial-opacity route lines, then the opacity is added as they overlay each other. However you would probably be better off doing some processing server- side to calculate the opacity rather than overlaying many route lines on a map: too many overlays can cripple performance in the client. > I am doing a college research for this topic, and do i need to contact > google map to purchase necessary packages? The API is free as long as your map is publicly accessible. If it's not, you need a premier licence: http://code.google.com/apis/maps/documentation/premier/ Andrew --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Maps API" group.
