Vector tile heat map This sample shows how to how to use a vector tile service to render data as a heat map. In this case traffic flow data is used. The points that make up the flow lines are used as the heat points. Points that have a traffic flow greater than 80% of the posted speed limit are ignored. The traffic level is used to weight each data point in the heat map.

This sample uses the Azure Maps vector tile traffic flow service. Detailed information about the format of the traffic flow vector tiles can be found here.
