Class: GeometryService

dojo.require("esri.tasks.geometry");

Description

(Added at v1.0)
Represents a geometry service resource exposed by the ArcGIS Server REST API. It is used to perform various operations on geometries such as project, simplify, buffer, and relationships.

It is recommended that you create a geometry service for use within your applications. View the About the geometry service help topic in the Server Resource Center for details. Esri hosts a geometry service at https://utility.arcgisonline.com/arcgis/rest/services/Geometry/GeometryServer. This service can be used for production applications however, we do not guarantee that the service will be available 24/7.
