Parameters

geometry1

The geometry from where the distance is to be measured.

geometry2

The geometry to which the distance is to be measured. The structure of geometry is same as the structure of the JSON geometry objects returned by the ArcGIS REST API. The use of simple syntax is not supported.

parameters

Parameters contains additional properties that defines how the distance task will be preformed.
