Itineraries

The itineraries used in the WemapSDKs are generated by the Wemap Routing API. The way you interact with the Wemap Routing API varies depending on which WemapSDK you use.

When you use:

To generate an itinerary, you’ll need to provide a destination, optionally origin and other options depending on which WemapSDK you use. You also can use the ItinerarySearchRules struct to set a few search rules. Wemap Routing API provides different travel modes for itinerary computation: walk, car and bike. Bike travel mode also can have TravelMode.Preference: default, safest, fastest and tourism.

Map Navigation Manager (WemapMapSDK)

To generate an itinerary and start navigation, you’ll need to obtain an instance implementing MapNavigationManaging from MapView.

func startNavigation() {

    let origin = Coordinate(latitude: 43.610628, longitude: 3.876654)
    let destination = Coordinate(latitude: 43.609011, longitude: 3.917091)

    let navigationOptions = NavigationOptions(stopWhenArrivedAtDestination: false) // NavigationOptions available for Map and AR SDKs
    let itineraryOptions = ItineraryOptions(indoorLine: .init(color: .red)) // ItineraryOptions available only for WemapMapSDK
    let searchRules: ItinerarySearchRules = .wheelchair // ItinerarySearchRules available for all SDKs

    mapView.navigationManager
        .startNavigation(
            origin: origin, destination: destination,
            travelMode: .walk, // can be omitted because it's default mode
            options: navigationOptions, searchRules: searchRules, itineraryOptions: itineraryOptions,
            timeout: .seconds(10) // default value is .seconds(30)
        )
        .subscribe(
            onSuccess: { _ in
                debugPrint("Successfully started navigation from: \(origin) to: \(destination)")
                self.mapView.userTrackingMode = .follow // track user movements
            },
            onFailure: { error in
                debugPrint("Failed to start navigation from \(origin) to: \(destination) with error: \(error)")
            }
        ).disposed(by: disposeBag)
}

Itinerary manager (WemapMapSDK)

To generate an itinerary for preview, you’ll need to obtain an instance of ItineraryManager class from MapView.

func getItinerariesForPreview() {

    let origin = Coordinate(latitude: 43.610628, longitude: 3.876654)
    let destination = Coordinate(latitude: 43.609011, longitude: 3.917091)

    let searchRules: ItinerarySearchRules = .wheelchair // ItinerarySearchRules available for all SDKs

    mapView.itineraryManager
        .getItineraries(
            origin: origin, destination: destination,
            travelMode: .walk, // can be omitted because it's default mode
            searchRules: searchRules
        )
        .subscribe(
            onSuccess: { itineraries in
                debugPrint("Successfully received itineraries from: \(origin) to: \(destination)")
                self.mapView.userTrackingMode = .follow // track user movements
                self.mapView.itineraryManager.addItinerary(itineraries.first!) // draw preview
            },
            onFailure: { error in
                debugPrint("Failed to receive itineraries from \(origin) to: \(destination) with error: \(error)")
            }
        ).disposed(by: disposeBag)
}

AR Navigation Manager (WemapGeoARSDK)

To generate an itinerary and start navigation, you’ll need to obtain an instance implementing ARNavigationManaging from GeoARView.

func startNavigation() {

    let origin = Coordinate(latitude: 43.610628, longitude: 3.876654)
    let destination = Coordinate(latitude: 43.609011, longitude: 3.917091)

    let navigationOptions = NavigationOptions(stopWhenArrivedAtDestination: false) // NavigationOptions available for Map and AR SDKs
    let searchRules: ItinerarySearchRules = .wheelchair // ItinerarySearchRules available for all SDKs

    geoARView.navigationManager
        .startNavigation(
            origin: origin, destination: destination,
            travelMode: .walk, // can be omitted because it's default mode
            options: navigationOptions, searchRules: searchRules,
            timeout: .seconds(10) // default value is .seconds(30)
        )
        .subscribe(
            onSuccess: { _ in
                debugPrint("Successfully started navigation from: \(origin) to: \(destination)")
            },
            onFailure: { error in
                debugPrint("Failed to start navigation from \(origin) to: \(destination) with error: \(error)")
            }
        ).disposed(by: disposeBag)
}

Itinerary Service (WemapCoreSDK)

To generate an itinerary, you’ll need to obtain an instance implementing ItineraryServicing and request for itinerary computation using ItineraryParameters class.

Below are examples of how you can use specific options to compute itineraries for a few scenarios.

Compute itinerary

This example demonstrates how to calculate walking itineraries with origin and destination coordinates.

func computeItineraries() {

    let origin = Coordinate(latitude: 43.610628, longitude: 3.876654)
    let destination = Coordinate(latitude: 43.609011, longitude: 3.917091)

    let parameters = ItineraryParameters(origin: origin, destination: destination) // default travelMode is .walk

    ServiceFactory
        .getItineraryService()
        .itineraries(parameters: parameters)
        .subscribe(
            onSuccess: { response in
                debugPrint("response - \(response)")
            }, onFailure: {
                debugPrint("error - \($0)")
            }
        )
        .disposed(by: disposeBag)
}

You can specify travel mode and preference for the request:

func computeItineraries() {
    ...
    let parameters = ItineraryParameters(
        origin: origin, destination: destination, travelMode: .bike(preference: .safest)
    )
    ...
}

Also is some cases you may need to specify search rules:

func computeItineraries() {
    ...
    let parameters = ItineraryParameters(
        origin: origin, destination: destination, travelMode: .walk, searchRules: .wheelchair
    )
    ...
}
