Route calculation with geocoding

The basic functionality of the SmartMaps API also includes the possibility to calculate arbitrary routes.

To calculate a route, at least the start and end point of the route is required. The coordinates of these points can be determined from address data, as this example demonstrates.

The example is complete you can save it locally in a file and open it in the browser. You only have to replace the value for the apiKey.
