Calculate distance-based isoline routing

A distance-based isoline, also called an Isodistance, can be requested using range[type]=distance and providing range[values] in meters.

mode can be either:

  • short: In this mode the isoline calculation simulates route calculation from start to destination minimizing route distance, disregarding any speed information.
  • fast: In this mode the isoline calculation simulates route calculation from start to destination minimizing travel time.

The request below calculates a 4 km isoline in the short mode. The response answers the question: what area can I reach by driving 4 km or less, while trying to take the shortest possible route?
