Service Area Task

Demonstrates how to find services areas around a point using the ServiceAreaTask. A service area shows locations that can be reached from a facility based off a certain impedance [such as travel time]. Barriers can also be added which can effect the impedance by not letting traffic through or adding the time is takes to pass that barrier.

How it works

To display service areas around a certain location:

  1. Create a ServiceAreaTask from an online service.
  2. Get ServiceAreaParameters from task, task.createDefaultParametersAsync().
  3. Setting return polygons to true will return all services areas, serviceAreaParameters.setReturnPolygons(true).
  4. Add a ServiceAreaFacilty to parameters, serviceAreaParameters.setFacilities(serviceAreaFacility).
  5. Get ServiceAreaResult by solving the service area task using parameters, task.solveServiceAreaAsync(serviceAreaParameters).get().
  6. Get any ServiceAreaPolygons that were returned, serviceAreaResult.getResultPolygons(facilityIndex).
    • facilityIndex is the faciltiy from the map view that you want to get the services areas of
  7. Display services areas to map view, graphicsOverlay.getGraphics().add(new Graphic(serviceAreaPolygon.getGeometry(), fillSymbol)).
