The Navigation Extension generates directions between two locations using a service called OpenRouteService. You must provide a valid API key from that service in order for this Extension to work.

EndLatitude

The latitude of the end location.

EndLocation

Set the end location.

EndLongitude

The longitude of the end location.

Language

ResponseContent

The raw response from the server. This can be used to access more details beyond what the GotDirections event provides.

StartLatitude

TransportationMethod

The transportation method used for determining the route. Valid options are:

GotDirections(directions,points,distance,duration)

Event indicating that a request has finished and has returned data. The following parameters are provided:

directions: A list of text directions, such as “Turn left at Massachusetts Avenue”.
points: A list of (latitude, longitude) points that represent the path to take. This can be passed to LineString’s Points to draw the line on a Map.
distance: Estimated distance for the route, in meters.
duration: Estimated duration for the route, in seconds.

RequestDirections(): Request directions from the routing service using the values of StartLatitude, StartLongitude, EndLatitude, and EndLongitude. On success, the GotDirections event block will run. If an error occurs, the error will be reported via the Screen's ErrorOccurred event.
