Routing API Developer's Guide

Reverse Direction Isoline

This example calculates an isoline in the reverse direction. The result is the answer to this question: From where can I get to the destination within a given range. This can be useful to determine which vehicles from a fleet of vehicles (Taxi service) can get to the destination within a given time, for example. To trigger calculation in reverse direction, use the destination parameter instead of start.
Note: This example uses a HERE API Key to authenticate your request. For information on other possible options, see For examples of how to use the other authentication options with the Routing API, see Authentication Examples.
