isPointInPolygon(lat, lon, polygon) → boolean · Geospatial

Checks if a point is inside a polygon using the ray casting algorithm.

• lat (required): point latitude

• lon (required): point longitude

• polygon (required): array of [lat, lon] coordinate pairs

let zone = [[52.0, 4.0], [52.5, 4.0], [52.5, 5.0], [52.0, 5.0]]
{
  inZone: isPointInPolygon($input.lat, $input.lon, zone)
}
