Podczas wyszukiwania miasta w Mapach Google wyświetlana jest granica administracyjna miasta.
Czy istnieje sposób na uzyskanie granic wielokąta miasta w formacie JSON przy użyciu interfejsu API Google Maps?

Odpowiedzi:
Możesz uzyskać współrzędne wielokąta w jsonie do używania z googlemaps przy użyciu openstreetmap. Idź do http://nominatim.openstreetmap.org/ szukaj miejsca takiego jak „Partido de Ituzaingó”
kliknij „szczegóły”
Wyszukaj identyfikator OSM i skopiuj go (control + c), przykład: 2018776
wklej identyfikator do http://polygons.openstreetmap.fr/index.py i pobierz wielokąt
źródło
5638803
, kiedy biegnę global.mapit.mysociety.org/code/osm_rel/5638803 mam{"code": 404, "error": "No areas were found that matched code osm_rel = 5638803."}
Aby uzyskać granice wielokątów, po prostu dodaj
format=json
do swojej prośby!Zamiast https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1
posługiwać się
https://nominatim.openstreetmap.org/search.php?q=Warsaw+Poland&polygon_geojson=1&format=json
Dodając & format = geojson, możesz uzyskać prawidłową odpowiedź geojson

Nie, nie ma sposobu na kradzież danych Google. Być może możesz spojrzeć na OpenStreetMap, która jest przeznaczona dla ludzi do pobrania.

Znalazłem rozwiązanie tego problemu.
Możesz używać lat, long data i parsować je w tablicę. To rozwiązanie działa dobrze, ale jakość ścieżki jest czasami trudna.

Jako alternatywa dla interfejsu API Map Google, OpenStreetMap może pomóc w wyszukiwaniu miasta według nazwy na tej stronie http://nominatim.openstreetmap.org/ . Następnie przejrzeć wyniki wyszukiwania, i można dostać obszar współrzędnych w formacie GeoJSON np ( http://nominatim.openstreetmap.org/details.php?place_id=145126778 ), aby uzyskać mashhad GeoJSON współrzędne w karcie Administracyjne

Uzyskaj dokładne współrzędne granic lokalizacji, takie jak wyszukiwarka Google, w formacie json.
