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.
