Leg

Contains the calculated route's details for each path between a pair of positions. The number of legs returned corresponds to one fewer than the total number of positions in the request.

For example, a route with a departure position and destination position returns one leg with the positions snapped to a nearby road:

  • The StartPosition is the departure position.

  • The EndPosition is the destination position.

A route with a waypoint between the departure and destination position returns two legs with the positions snapped to a nearby road:

  • Leg 1: The StartPosition is the departure position . The EndPosition is the waypoint positon.

  • Leg 2: The StartPosition is the waypoint position. The EndPosition is the destination position.

Distance

The distance between the leg's StartPosition and EndPosition along a calculated route.

  • The default measurement is Kilometers unless the request specifies a DistanceUnit of Miles.

Type: Double

Valid Range: Minimum value of 0.

Required: Yes

DurationSeconds

The estimated travel time between the leg's StartPosition and EndPosition. The travel mode and departure time that you specify in the request determines the calculated time.

Type: Double

Valid Range: Minimum value of 0.

Required: Yes

EndPosition

The terminating position of the leg. Follows the format [longitude,latitude].

Note

If the EndPosition isn't located on a road, it's snapped to a nearby road.

Type: Array of doubles

Array Members: Fixed number of 2 items.

Required: Yes

StartPosition

The starting position of the leg. Follows the format [longitude,latitude].

Note

If the StartPosition isn't located on a road, it's snapped to a nearby road.

Type: Array of doubles

Array Members: Fixed number of 2 items.

Required: Yes

Steps

Contains a list of steps, which represent subsections of a leg. Each step provides instructions for how to move to the next step in the leg such as the step's start position, end position, travel distance, travel duration, and geometry offset.

Type: Array of Step objects

Required: Yes

Geometry

Contains the calculated route's path as a linestring geometry.
