Parameter
| Nama | Tipe | Wajib | Deskripsi |
|---|---|---|---|
| Bujur | real |
✔️ | Koordinat geospasial, nilai bujur dalam derajat. Nilai valid adalah bilangan real dan dalam rentang [-180, +180]. |
| lintang | real |
✔️ | Koordinat geospasial, nilai lintang dalam derajat. Nilai valid adalah bilangan real dan dalam rentang [-90, +90]. |
| polygon | dynamic |
✔️ | Poligon atau multipoligon dalam format GeoJSON. |
Mengembalikan
Menunjukkan apakah koordinat geospasial berada di dalam poligon. Jika koordinat atau poligon tidak valid, kueri menghasilkan hasil null.
Catatan
- Koordinat geospasial diinterpretasikan sebagaimana diwakili oleh sistem referensi koordinat WGS-84.
- Datum geodetik yang digunakan untuk pengukuran di Bumi adalah bola. Tepi poligon adalah geodesik pada bola.
- Jika tepi poligon input adalah garis kartesius lurus, pertimbangkan untuk menggunakan geo_polygon_densify() untuk mengonversi tepi planar menjadi geodesik.
Definisi dan batasan poligon
dynamic({"type": "Polygon","coordinates": [ LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ]})
dynamic({"type": "MultiPolygon","coordinates": [[LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ], ..., [LinearRingShell, LinearRingHole_1, ..., LinearRingHole_M]]})
- LinearRingShell diperlukan dan didefinisikan sebagai array berurutan koordinat
counterclockwise[[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Hanya boleh ada satu shell. - LinearRingHole diperlukan dan didefinisikan sebagai array berurutan koordinat
clockwise[[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Mungkin ada sejumlah cincin dan lubang interior. - Puncak LinearRing harus berbeda dengan setidaknya tiga koordinat. Koordinat pertama harus sama dengan yang terakhir. Setidaknya empat entri yang diperlukan.
- Koordinat [garis bujur, garis lintang] harus valid. Bujur harus berupa bilangan real dalam rentang [-180, +180] dan garis lintang berupa menjadi bilangan real dalam rentang [-90, +90].
- LinearRingShell menutup paling banyak setengah dari bola. LinearRing membagi bola menjadi dua wilayah. Yang lebih kecil dari dua wilayah, dipilih.
- Panjang tepi LinearRing harus kurang dari 180 derajat. Tepi terpendek antara dua simpul dipilih.
- LinearRing tidak boleh bersilangan dan tidak boleh berbagi tepi. LinearRings mungkin berbagi simpul.
- Poligon belum tentu berisi puncaknya. Penahanan titik dalam poligon didefinisikan sehingga jika Bumi dibagi lagi menjadi poligon, setiap titik terkandung oleh tepat satu poligon.
Tip
- Menggunakan Polygon literal atau MultiPolygon dapat menghasilkan performa yang lebih baik.
- Jika Anda ingin tahu apakah salah satu poligon berisi titik, coba langkah-langkah berikut: Lipat koleksi poligon menjadi satu multipoligon. Kemudian kueri multipoligon ini. Hal ini dapat meningkatkan performa. Lihat contoh berikut.
Contoh
Contoh berikut menemukan lokasi yang berada di dalam pulau Manhattan, tidak termasuk area Central Park.
