Routing API v7 Developer's Guide

Request an Isoline

Use calculateisoline to calculate the area that a driver can reach within a given time or distance. The following parameters are mandatory:

  • your authentication credentials, apiKey or app_id and app_code if you are using the app_id/app_code authentication (see Acquiring Credentials)
  • the start (start) or destination (destination) position
  • the mode, which describes the type of route calculation and whether to optimize the routing for traffic conditions or not
  • range of route (range)
  • and type of range (distance, time, consumption) (rangetype)

The request below calculates a 4km isoline around the center of Berlin. This answers the question: what area can I reach by travelling no more than 4km?

?apiKey={YOUR_API_KEY}
&mode=shortest;car;traffic:disabled
&start=geo!52.51578,13.37749
&range=4000
&rangetype=distance
Note: This example uses a HERE API Key to authenticate your request. For information on other possible options, see Authentication Guide. For examples of how to use the other authentication options with the Routing API v7, see Authentication Examples.
