geo_point_in_polygon()
Calcula si las coordenadas geoespaciales están dentro de un polígono o un multipolígono en la Tierra.
Syntax
geo_point_in_polygon(Longitud,Latitud,Polígono)
Más información sobre las convenciones de sintaxis.
Parámetros
| Nombre | Tipo | Requerido | Descripción |
|---|---|---|---|
| longitude | real |
✔️ | Coordenada geoespacial, valor de longitud en grados. El valor válido es un número real y en el intervalo [-180, +180]. |
| latitude | real |
✔️ | Coordenada geoespacial, valor de latitud en grados. El valor válido es un número real y en el intervalo [-90, +90]. |
| Polígono | dynamic |
✔️ | Polígono o multipolígono en formato GeoJSON. |
Devoluciones
Indica si las coordenadas geoespaciales están dentro de un polígono. Si las coordenadas o el polígono no son válidas, la consulta genera un resultado nulo.
Nota
- Las coordenadas geoespaciales se interpretan como representadas por el sistema de referencia de coordenadas WGS-84 .
- La referencia geodética utilizada para las mediciones en la Tierra es una esfera. Los bordes de polígono son geodesics en la esfera.
- Si los bordes de polígono de entrada son líneas cartesianas rectas, considere la posibilidad de usar geo_polygon_densify() para convertir bordes planales en geodesics.
Definición y restricciones de polígono
dynamic({"type": "Polygon","coordinates": [ LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ]})
dynamic({"type": "MultiPolygon","coordinates": [[LinearRingShell, LinearRingHole_1, ..., LinearRingHole_N ], ..., [LinearRingShell, LinearRingHole_1, ..., LinearRingHole_M]]]})
- LinearRingShell es necesario y se define como una
counterclockwisematriz ordenada de coordenadas [[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Solo puede haber un shell. - LinearRingHole es opcional y se define como una
clockwisematriz ordenada de coordenadas [[lng_1,lat_1],...,[lng_i,lat_i],...,[lng_j,lat_j],...,[lng_1,lat_1]]. Puede haber cualquier número de anillos interiores y agujeros. - Los vértices linearRing deben ser distintos con al menos tres coordenadas. La primera coordenada debe ser igual a la última. Se requieren al menos cuatro entradas.
- Las coordenadas [longitud, latitud] deben ser válidas. La longitud debe ser un número real en el intervalo [-180, +180] y la latitud debe ser un número real en el intervalo [-90, +90].
- LinearRingShell incluye como máximo la mitad de la esfera. LinearRing divide la esfera en dos regiones. Se elige el menor de las dos regiones.
- La longitud del borde linearRing debe ser inferior a 180 grados. Se elige el borde más corto entre los dos vértices.
- LinearRings no debe cruzar y no compartir bordes. LinearRings puede compartir vértices.
- Polygon no contiene necesariamente sus vértices. La contención de punto en polígono se define para que si la Tierra se subdivide en polígonos, cada punto está contenido exactamente por un polígono.
Sugerencia
- El uso de polygon literal o un multipolygon puede dar lugar a un mejor rendimiento.
- Si desea saber si alguno de los polígonos contiene un punto, pruebe los pasos siguientes: Plegar la colección de polígonos en un multipolygon. A continuación, consulte este multipolygon. Esto puede mejorar el rendimiento. Consulte el ejemplo siguiente.
Ejemplos
En el ejemplo siguiente se buscan ubicaciones que se encuentran dentro de la isla de Manhattan, excepto el área de Central Park.
