GetTravelBoundary

Description

GetTravelBoundary determines a drive or walk time or distance boundary from a location. This feature obtains polygons corresponding to an isochrone or isodistance calculation. An isochrone is a polygon or set of points representing an area that can be traversed in a network from a starting point in a given amount of time. An isodistance is a polygon or set of points representing the area that is a certain distance from the starting point. The GetTravelBoundary operation (also known as an iso definition) takes a starting point, a unit (linear or time), one or more costs as input and returns the resulting travel boundary. Costs refer to the amount of time or distance to use in calculating an iso. Multiple costs can also be given as input. In case of multiple costs, costs can also be provided as a comma delimited string.

Note: The response from the REST service will be in JSON format. When a request contains invalid query parameters in the GET URL or an invalid payload for POST, a cumulative error response will be returned in a JSON array. The value node in the response JSON is deprecated. For error checking, only the errors node should be utilized.
