Re: GWT and Google Maps API
Sure, I have already taken a deep look at the API libraries and even experimented a little bit. Currently I am able to create a route between two addresses and display this route as a polyline. This polyline has n vertexes. Now I am pondering about how to move a graphical object along this polyline at a given speed. Any advices? Thanks in Advance!

Re: [Basic] GWT and Google Maps API
Have you seen the Google API libraries for GWT http://code.google.com/p/gwt-google-apis On Mon, Nov 8, 2010 at 2:27 PM, StrongSteve wrote: > Hello Group, > > I am currently doing some basic research for an upcoming project of > mine. > > Basically I want to simulate a large number of driving cars on Google > Maps. > The way I imagine it right now is that I want to define a startpoint > and an endpoint.

[Basic] GWT and Google Maps API
Hello Group, I am currently doing some basic research for an upcoming project of mine. Basically I want to simulate a large number of driving cars on Google Maps. The way I imagine it right now is that I want to define a startpoint and an endpoint. Either by GPS Coordinates (xx° yy' zz'') or by an address (f.e. City, Street, Number) for every car. Then I would like Google Maps to calculate the route between the start and endpoint. (Preferably the shortes route) Last but not least a graphic symbol - at least a colored dot - should simulate the driving of a vehicle from the start point to the end point. This should occur in realtime and in addition simulated at lets say 500% of the normal speed. Some kind of a simulation mode. Of course the dot - the car - should move along the streets and not directly from start to end. Is this possible using GWT and the Google Maps API? Can anyone point out best practices, maybe even existing samples? Thanks in Advance for both your time and your help!
