geo.ST_Intersects() function

The geo.ST_Intersects() function is experimental and subject to change at any time. By using this function, you accept the risks of experimental functions.

The geo.ST_Intersects() function tests if the specified geographic information system (GIS) geometry intersects with the specified region and returns true or false.

*Function type: Test*

import "experimental/geo"
geo.ST_Intersects(
  region: {lat: 40.7, lon: -73.3, radius: 20.0},
  geometry: {linestring: "39.7515 14.01433, 38.3527 13.9228, 36.9978 15.08433"}
)
// Returns false

Parameters

region

The region to test. Specify record properties for the shape. See Region definitions.

*Data type: Record*

geometry

The GIS geometry to test. Can be either point or linestring geometry. See GIS geometry definitions.

*Data type: Record*

Examples

Test if geographic points intersect with a region

  minLat: 40.51757813,
  maxLat: 40.86914063,
  minLon: -73.65234375,
  maxLon: -72.94921875
