Mendapatkan batas poligon Kota di JSON dari Google Maps API?

Saat mencari Google Maps untuk sebuah kota, batas administratif kota ditampilkan.

Apakah ada cara untuk mendapatkan batas poligon Kota dalam format JSON menggunakan google maps api?

Anda bisa mendapatkan koordinat poligon di json untuk digunakan dengan googlemaps menggunakan openstreetmap. Pergi ke http://nominatim.openstreetmap.org/ cari tempat seperti "Partido de Ituzaingó"

klik pada "detail"

Cari ID OSM dan salin (kontrol + c), contoh: 2018776

rekatkan ID di http://polygons.openstreetmap.fr/index.py dan unduh poligon

Untuk mendapatkan batas poligon cukup tambahkan format=jsonke permintaan Anda!

Jadi alih-alih https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1

menggunakan

https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1&format=json

Dengan menambahkan & format = geojson, Anda bisa mendapatkan respons geojson yang valid

Tidak, tidak ada cara untuk mencuri data Google. Mungkin Anda bisa melihat OpenStreetMap yang dirancang untuk diunduh orang.

Saya telah menemukan solusi untuk masalah ini.

1. Kunjungi www.gadm.org/country
2. Pilih negara Anda dan pilih format file Google Earth .kmz
3. Pilih level yang Anda butuhkan (level 3 adalah yang terdalam dengan semua kota kecil / kota kecil)
4. Unduh file (bisa besar)
5. Buka zip file .kmz (Anda akan menemukan .kml yang merupakan XML)
6. Buka dengan Sublime atau notepad ++ (file mungkin akan terlalu besar untuk editor teks lainnya)
7. Cari berdasarkan nama kota dan salin data di bawah (Pencarian dapat memakan waktu 1 hingga 4 detik dengan file besar)

Anda bisa menggunakan lat, data panjang dan menguraikannya ke dalam array. Solusi ini bekerja dengan baik, tetapi kualitas jalur terkadang kasar.

Sebagai alternatif dari Google Maps API, OpenStreetMap dapat membantu Anda untuk mencari kota dengan nama di halaman ini http://nominatim.openstreetmap.org/ . Kemudian tinjau hasil pencarian, dan Anda bisa mendapatkan koordinat wilayah dalam format GeoJSON misalnya ( http://nominatim.openstreetmap.org/details.php?place_id=145126778 ) untuk mendapatkan koordinat mashhad geojson di tab Administratif

Dapatkan koordinat batas lokasi yang tepat seperti pencarian google dalam format json.
