Before using the Location Selection API to search for ride
pickup points, follow the instructions
to integrate with the client library .
The Location Selection service provides three APIs for pickup and dropoff
selection: FindNearbyPlaces, FindPickupPointsForPlace, and
FindPickupPointsForLocation.
Use FindNearbyPlaces to fetch places near the search or device location. The
places are ranked by proximity to the location and their prominence for
ridesharing. FindNearbyPlaces returns a list of places that can be displayed
to let the user make the best selection. Once a place is selected, use
FindPickupPointsForPlace to fetch pickup points for the selected place.
Use FindPickupPointsForLocation to fetch places and their associated pickup
points near the search or device location in the same RPC call.
Each pickup point
is associated with a place. The pickup points are ranked by proximity to the
location and their prominence for ridesharing. Note that pickup points for
multiple places are ordered together. FindPickupPointsForLocation combines
FindNearbyPlaces and FindPickupPointsForPlace. For example, say the request
location is near Place P1, P2 and P3. If the best pickup point T1 is associated
with Place P2 and the next best pickup point is associated with Place P1, the
results will have the ordering [T1:P2, T2:P1, ...].
The ranking of pickup points depends on the criteria provided in the request.
For more information, see
Optimizing pickups for multiple trips .
Search by location
If you prefer to display places to the user prior to selection of pickup points,
or display nearby places by dragging a pin, use the following RPC call:
FindNearbyPlacesRequest find_nearby_places_request =
FindNearbyPlacesRequest.newBuilder()
.setLocalizationPreferences(LocalizationPreferences.newBuilder()
// Language used for localizing text such as name or address.
.setLanguageCode("en")
.setRegionCode("US")
.build())
// Rider's location or location of dragged pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.365647).setLongitude(-121.925356))
// Number of places requested.
.setMaxResults(3)
.build();
FindNearbyPlacesResponse findNearbyPlacesResponse =
locationSelectionBetaClient.findNearbyPlaces(find_nearby_places_request);
The RPC call returns a ranked list of place responses that satisfy the input
criteria, ordered by a combination of proximity and prominence. You can let the
rider choose a place or use the first result and proceed to the pickup point
selection. Each place response has a unique place_id that can be used in
FindPickupPointsForPlaceRequest to fetch pickup points. For more information,
see Search by place id .
FindPickupPointsForLocationRequest FindPickupPointsForLocationRequest =
FindPickupPointsForLocationRequest.newBuilder()
// Language used for localizing text such as name and address.
.setLocalizationPreferences(LocalizationPreferences.newBuilder().setRegionCode("US").setLanguageCode("en"))
// The search location of the rider or the dropped pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(-23.482049).setLongitude(-46.602135))
// The max results returned.
.setMaxResults(5)
// List of travel modes. At least one of the travel modes must be supported by the pickup points.
.addTravelModes(TravelMode.DRIVING)
// Specifies the sorting order of matching pickup points.
.setOrderBy(PickupPointOrder.DISTANCE_FROM_SEARCH_LOCATION)
.build();
FindPickupPointsForLocationResponse FindPickupPointsForLocationResponse =
locationSelectionService.FindPickupPointsForLocation(
RpcClientContext.create(), FindPickupPointsForLocationRequest);
The RPC call returns a ranked list of pickup points that satisfy the input
criteria, ordered by a combination of proximity and prominence. This RPC call
combines FindNearbyPlaces and FindPickupPointsForPlaceRequest and can be
used instead of combining the other two calls.
Search by place ID
You can obtain a place_id using FindNearbyPlaces or
by using the Places API
Autocomplete service. Then use the following RPC call to provide optimal pickup
points for the specified place:
FindPickupPointsForPlaceRequest findPickupPointsForPlaceRequest =
FindPickupPointsForPlaceRequest.newBuilder()
// Language used for localizing text such as name and address.
.setLocalizationPreferences(LocalizationPreferences.newBuilder().setRegionCode("US").setLanguageCode("en"))
// Place ID of the place for which pickup points are being fetched;
// for example, Hilton Hotel, Downtown San Jose.
.setPlaceId("ChIJwTUa-q_Mj4ARff4yludGH-M")
// List of travel modes. At least one of the travel modes must be supported by the pickup points.
.addTravelModes(TravelMode.DRIVING)
// Rider's location or location of dragged pin.
// It is recommended to use the same location that was used in `FindNearbyPlaces` for better quality.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
.setOrderBy(PickupPointOrder.DISTANCE_FROM_SEARCH_LOCATION)
.setMaxResults(5)
.build();
FindPickupPointsForPlaceResponse findPickupPointsForPlaceResponse =
locationSelectionBetaClient.findPickupPointsForPlace(findPickupPointsForPlaceRequest);
FindPickupPointsForPlace returns PickupPointResponses with latitude and
longitude for the
points where a rider can be picked up.
Optimize pickups for multiple trips
For shared or back-to-back rides, FindPickupPointsForPlace supports ordering
pickup points by DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION. This lets you
return a pickup point for the next trip that is optimized with the driver's
current trip route.
Example
FindPickupPointsForPlaceRequest findPickupPointsForPlaceRequest =
FindPickupPointsForPlaceRequest.newBuilder()
// Language used for localizing text such as name and address.
.setLocalizationPreferences(LocalizationPreferences.newBuilder().setRegionCode("US").setLanguageCode("en"))
// Place ID of the place for which pickup points are being fetched;
// for example, Hilton Hotel, Downtown San Jose.
.setPlaceId("ChIJwTUa-q_Mj4ARff4yludGH-M")
// List of travel modes. At least one of the travel modes must be supported by the pickup points.
.addTravelModes(TravelMode.DRIVING)
// Second rider's location or location of dragged pin.
.setSearchLocation(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
// Location of the driver's next drop off after picking up the second
// rider. Note, it is not necessarily the second rider's destination.
.setDestination(LatLng.newBuilder().setLatitude(37.329472).setLongitude(-121.890449))
.setOrderBy(PickupPointOrder.DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION)
.setComputeDrivingEta(true)
.setMaxResults(5)
.build();
FindPickupPointsForPlaceResponse findPickupPointsForPlaceResponse =
locationSelectionBetaClient.findPickupPointsForPlace(findPickupPointsForPlaceRequest);
Display building outlines, entrances, and exits
Within the place proto response message, the
associatedCompounds
Compound type - one of four options
compoundBuilding - a single standalone building, such as a mall or
supermarket.compoundSection - a compound within a larger compound, such as a single
store in a mall.compoundGrounds - everything associated with a compoundBuilding,
such as a mall, its parking lot, and any other buildings
within that parking lot.unrecognized - the default value
Geometry - the coordinates of the outlined polygon, stored in a GeoJSON
structure in the displayBoundary field. These coordinates are used to
construct the outline of the section, building, or grounds.
Entrances - the latitude and longitude coordinates of all located entrances
and exits.
Location Selection returns any compound type associated
with the search location. If the search location is in a particular store in
a mall, Location Selection returns:
* the specific store, its entrances and exits, and the outline of the store
* the compound building (the mall), its entrances and exits, and the outline of the mall
* the compound grounds (the mall + parking lot), their entrances and exits, and the outline of the entire grounds
This image shows all three compound types being returned.
This image shows several locations inside an airport, with the boundary of both
a building within the airport and the boundary of the airport and all of its
related grounds.
