geo_point_in_polygon()

  • Articolo

Calcola se le coordinate geospaziali si trovano all'interno di un poligono o un multipolygon sulla Terra.

Sintassi

geo_point_in_polygon(Longitudine,Latitudine,Poligono)

Altre informazioni sulle convenzioni di sintassi.

Parametri

Nome Tipo Obbligatoria Descrizione
longitude real ✔️ Coordinate geospaziali, valore di longitudine in gradi. Il valore valido è un numero reale e nell'intervallo [-180, +180].
latitude real ✔️ Coordinate geospaziali, valore della latitudine in gradi. Il valore valido è un numero reale e nell'intervallo [-90, +90].
Poligono dynamic ✔️ Poligono o multipolygon nel formato GeoJSON.

Restituisce

Indica se le coordinate geospaziali si trovano all'interno di un poligono. Se le coordinate o il poligono non sono valide, la query genera un risultato Null.

Nota

  • Le coordinate geospaziali vengono interpretate come rappresentate dal sistema di riferimento di coordinate WGS-84 .
  • La datum geodetica usata per le misurazioni sulla Terra è una sfera. I bordi poligono sono geodesici sulla sfera.
  • Se i bordi poligono di input sono linee cartesiane dritte, prendere in considerazione l'uso di geo_polygon_densify() per convertire i bordi planari in geodesici.

Definizione e vincoli poligono

dynamic({"type": "Polygon","coordinates": [ LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ]})

dynamic({"type": "MultiPolygon","coordinates": [[LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ], ..., [LinearRingShell, LinearRingHole_1, ..., LinearRingHole_M]]))

  • LinearRingShell è obbligatorio e definito come matrice counterclockwise ordinata di coordinate [[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Può essere presente una sola shell.
  • LinearRingHole è facoltativo e definito come matrice clockwise ordinata di coordinate [[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Può essere presente un numero qualsiasi di anelli e fori interni.
  • I vertici LinearRing devono essere distinti con almeno tre coordinate. La prima coordinata deve essere uguale all'ultima. Sono necessarie almeno quattro voci.
  • Le coordinate [longitudine, latitudine] devono essere valide. La longitudine deve essere un numero reale nell'intervallo [-180, +180] e latitudine deve essere un numero reale nell'intervallo [-90, +90].
  • LinearRingShell racchiude la metà della sfera. LinearRing divide la sfera in due aree. Viene scelto il più piccolo delle due regioni.
  • La lunghezza del bordo LinearRing deve essere inferiore a 180 gradi. Il bordo più corto tra i due vertici viene scelto.
  • LinearRings non deve attraversare e non condividere i bordi. LinearRings potrebbe condividere vertici.
  • Poligono non contiene necessariamente i vertici. Il contenimento del punto nel poligono è definito in modo che se la Terra è suddivisa in poligoni, ogni punto è contenuto da un poligono esattamente.

Suggerimento

  • L'uso del poligono letterale o di un multipolygon può comportare prestazioni migliori.
  • Se si vuole sapere se uno dei poligoni contiene un punto, provare i passaggi seguenti: Piegare la raccolta di poligoni in un multipolygon. Eseguire quindi una query su questo multipolygon. Ciò può migliorare le prestazioni. Vedere l'esempio seguente.

Esempio

Nell'esempio seguente vengono trovate località che rientrano nell'isola di Manhattan, escluse l'area di Central Park.
