Routing Layer

The L.ALKMaps.Layer.Routing layer is used to retrieve, display, and get reports for routes.

Add A Route

Once you have added a routing layer to your map, you can begin adding routes to the layer. The addRoute function of the routing layer has up to six parameters: stops, options, functionOptions, reportOptions, and the success and failure callback functions. Descriptions for these parameters can be found in the table below.

Stops

The stops parameter of the addRoute method should contain an array of L.latLng objects representing the stops of the route.

Options

The options parameter contains options related to the generation of the route and optional reports.
