Note

Bing Maps Calculate a Route API retirement

Bing Maps Calculate a Route API is deprecated and will be retired. Free (Basic) account customers can continue to use Bing Maps Calculate a Route API until June 30th, 2025. Enterprise account customers can continue to use Bing Maps Calculate a Route API until June 30th, 2028. To avoid service disruptions, all implementations using Bing Maps Calculate a Route API will need to be updated to use Azure Maps Route Directions API by the retirement date that applies to your Bing Maps for Enterprise account type. For detailed migration guidance, see Migrate Bing Maps Calculate a Route API.

Azure Maps is Microsoft's next-generation maps and geospatial services for developers. Azure Maps has many of the same features as Bing Maps for Enterprise, and more. To get started with Azure Maps, create a free Azure subscription and an Azure Maps account. For more information about azure Maps, see Azure Maps Documentation. For migration guidance, see Bing Maps Migration Overview.

The following example shows how to request a driving route between two locations and specifies tolerances so that subsets of route points that meet those tolerances are returned. Each tolerance returns a subset of route points in the response. The route path defined by the subset of route path points approximates the route path defined by the full set of route points within the tolerance provided. The response to this request is the same as are shown for both XML and JSON formats.

This example is the same as the request that is described in the Driving Route with Route Path Example with the addition of tolerances. Examples of the additional content that is returned when tolerances are specified are shown below in JSON and XML formats.

JSON Response

The following route path generalization collections are returned with the route path points in Route resource in the response. Each route path generalization specifies a subset of route path points and the associated tolerance (latLongTolerance). The route path points are specified by an index value. Route path points are assigned integer index values that start with 0.

These generalizations would be added to the complete response shown in Driving Route with Route Path Example.
