AGSServiceAreaTask Class Reference

---

Description

Instances of this class represent tasks that can compute service areas. A service area is a region that encompasses all accessible streets, that is, streets that lie within a specified impedance. For instance, the 10-minute service area for a facility includes all the streets that can be reached within 10 minutes from that facility.

A service area task needs a URL to a REST resource that represents a Service Area layer in a Network Analyst service. For example, http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Network/USA/NAServer/Service%20Area

Availability:

This feature is only available with services from ArcGIS Server 10.0 or above
