Description

A geometry service contains utility methods, which provide access to sophisticated and frequently used geometric operations. An ArcGIS Server Web site can only expose one geometry service with the static name "Geometry." Note that geometry input and output, where required, are always packaged as an array.

Use a geometry service to:

• Buffer, project, and simplify geometry
• Calculate areas and lengths for geometry
• Determine spatial relations and label points

The REST API geometry service resource is primarily a processing and algorithmic resource that supports operations related to geometries. The geometry service resource has the following operations:

• Project - Returns an array of projected geometries.
• Simplify - Returns an array of simplified geometries.
• Buffer - Returns an array of polygons at the specified distances for the input geometry. An option is available to union buffer polygons at each distance.
• Areas and lengths - Calculates areas and perimeter lengths for each polygon specified in the input array.
• Lengths - Calculates the lengths of each polyline specified in the input array.
• Relation - Determines the pairs of geometries from the input geometry arrays that participate in the specified spatial relation.
• Label Points - Calculates an interior point for each polygon specified in the input array.
