geo.ST_DWithin() function

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

The geo.ST_DWithin() function tests if the specified region is within a defined distance from the specified geographic information system (GIS) geometry and returns true or false.

import "experimental/geo"

    region: {lat: 40.7, lon: -73.3, radius: 20.0},
    geometry: {lon: 39.7515, lat: 15.08433},
    distance: 1000.0,

// Returns false



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


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


Maximum distance allowed between the region and geometry. Define distance units with the geo.units option.
