You can use a RouteTask object to find routes between two or more locations, and optionally to get driving directions. The RouteTask uses a network analysis service to calculate the routes, which can be both simple (what's the quickest way to get from A to B?) and complex (involving multiple stops, barriers, and time windows). The RouteTask uses a least-cost path between multiple locations in a network. Impedance on the network can include time and distance variables:
As with the other tasks we have examined in this book so far, routing is accomplished through a series of objects including RouteParameters, RouteTask, and RouteResult:
The RouteParameters object provides the input parameters to RouteTask which executes the routing operation. Results are returned from ArcGIS Server in the form of a RouteResult object.
RouteParameters can include stop and barrier locations, impedance factors, whether or not to return driving directions, and many other options, too many to go into in...
