ES|QL ST_DISTANCE function

×

geomA

Expression of type geo_point or cartesian_point. If null, the function returns null.

geomB

Expression of type geo_point or cartesian_point. If null, the function returns null. The second parameter must also have the same coordinate system as the first. This means it is not possible to combine geo_point and cartesian_point parameters.

Computes the distance between two points. For cartesian geometries, this is the pythagorean distance in the same units as the original coordinates. For geographic geometries, this is the circular distance along the great circle in meters.
