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
import "experimental/geo"
region = {
minLat: 40.51757813,
maxLat: 40.86914063,
minLon: -73.65234375,
maxLon: -72.94921875
