Sebelum menggunakan Location Selection API untuk menelusuri titik penjemputan perjalanan, ikuti petunjuk untuk berintegrasi dengan library klien .
Layanan Pemilihan Lokasi menyediakan tiga API untuk pemilihan lokasi pengambilan dan pengantaran: FindNearbyPlaces, FindPickupPointsForPlace, dan FindPickupPointsForLocation.
Gunakan FindNearbyPlaces untuk mengambil data tempat di dekat lokasi penelusuran atau perangkat. Tempat
diberi peringkat berdasarkan kedekatannya dengan lokasi dan visibilitasnya untuk
layanan transportasi online. FindNearbyPlaces menampilkan daftar tempat yang dapat ditampilkan
untuk memungkinkan pengguna membuat pilihan terbaik. Setelah tempat dipilih, gunakan
FindPickupPointsForPlace untuk mengambil titik pengambilan untuk tempat yang dipilih.
Gunakan FindPickupPointsForLocation untuk mengambil data tempat dan titik pengambilan terkait di dekat lokasi penelusuran atau perangkat dalam panggilan RPC yang sama.
Setiap titik pengambilan
dikaitkan dengan suatu tempat. Titik penjemputan diberi peringkat berdasarkan kedekatan dengan lokasi dan keunggulan titik tersebut untuk layanan berbagi tumpangan. Perhatikan bahwa lokasi pengambilan untuk beberapa tempat diurutkan bersama. FindPickupPointsForLocation menggabungkan
FindNearbyPlaces dan FindPickupPointsForPlace. Misalnya, lokasi permintaan
berada di dekat Tempat P1, P2, dan P3. Jika titik pengambilan terbaik T1 dikaitkan
dengan Tempat P2 dan titik pengambilan terbaik berikutnya dikaitkan dengan Tempat P1, maka
hasilnya akan memiliki urutan [T1:P2, T2:P1, ...].
Peringkat titik pengambilan bergantung pada kriteria yang diberikan dalam permintaan.
Untuk mengetahui informasi selengkapnya, lihat Mengoptimalkan penjemputan untuk beberapa perjalanan .
Telusuri menurut lokasi
Jika Anda lebih memilih untuk menampilkan tempat kepada pengguna sebelum pemilihan titik pengambilan,
atau menampilkan tempat terdekat dengan menarik pin, gunakan panggilan RPC berikut:
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);
Panggilan RPC menampilkan daftar respons tempat yang diberi peringkat dan memenuhi kriteria
input, yang diurutkan berdasarkan kombinasi kedekatan dan keunggulan. Anda dapat membiarkan penumpang memilih tempat atau menggunakan hasil pertama dan melanjutkan ke pemilihan titik penjemputan. Setiap respons tempat memiliki place_id unik yang dapat digunakan di
FindPickupPointsForPlaceRequest untuk mengambil titik pengambilan. Untuk mengetahui informasi selengkapnya, lihat Menelusuri berdasarkan ID tempat .
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);
Panggilan RPC menampilkan daftar peringkat titik pengambilan yang memenuhi kriteria input, yang diurutkan berdasarkan kombinasi kedekatan dan keunggulan. Panggilan RPC ini
menggabungkan FindNearbyPlaces dan FindPickupPointsForPlaceRequest dan dapat
digunakan sebagai ganti menggabungkan dua panggilan lainnya.
Menelusuri berdasarkan ID tempat
Anda dapat memperoleh place_id menggunakan FindNearbyPlaces atau
dengan menggunakan layanan Autocomplete Places API. Kemudian, gunakan panggilan RPC berikut untuk memberikan titik pengambilan yang optimal untuk tempat yang ditentukan:
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 menampilkan PickupPointResponses dengan garis lintang dan bujur untuk titik tempat penumpang dapat dijemput.
Mengoptimalkan pengambilan untuk beberapa perjalanan
Untuk perjalanan bersama atau berurutan, FindPickupPointsForPlace mendukung pengurutan
titik penjemputan berdasarkan DRIVING_ETA_FROM_PICKUP_POINT_TO_DESTINATION. Dengan demikian, Anda dapat
menampilkan titik pengambilan untuk perjalanan berikutnya yang dioptimalkan dengan rute perjalanan pengemudi saat ini.
Contoh
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)

Menampilkan garis batas bangunan, pintu masuk, dan pintu keluar
Dalam pesan respons proto tempat, kolom
associatedCompounds
Jenis gabungan - salah satu dari empat opsi
compoundBuilding - satu bangunan mandiri, seperti mal atau supermarket.compoundSection - senyawa dalam senyawa yang lebih besar, seperti satu
toko di pusat perbelanjaan.compoundGrounds - semua yang terkait dengan compoundBuilding,
seperti mal, tempat parkirnya, dan bangunan lain
di dalam tempat parkir tersebut.unrecognized - nilai default
Geometri - koordinat poligon yang digarisbawahi, disimpan dalam struktur GeoJSON di kolom displayBoundary. Koordinat ini digunakan untuk
membuat garis batas bagian, bangunan, atau area.
Pintu masuk - koordinat lintang dan bujur semua pintu masuk dan pintu keluar yang ditemukan.
Pemilihan Lokasi menampilkan jenis gabungan apa pun yang terkait
dengan lokasi penelusuran. Jika lokasi penelusuran berada di toko tertentu di dalam mal, Pemilihan Lokasi akan menampilkan:
* toko tertentu, pintu masuk dan keluarnya, serta garis batas toko
* bangunan gabungan (mal), pintu masuk dan keluarnya, serta garis batas mal
* area gabungan (mal + tempat parkir), pintu masuk dan keluarnya, serta garis batas seluruh area
Gambar ini menampilkan ketiga jenis gabungan yang ditampilkan.
Gambar ini menunjukkan beberapa lokasi di dalam bandara, dengan batas bangunan di dalam bandara dan batas bandara serta semua area terkaitnya.
