Description

A Geometry Service contains utility methods that provide access to sophisticated and frequently used geometric operations. An ArcGIS Server website can only expose one geometry service with the static name Geometry.

Note:

Geometry input and output, where required, are usually packaged as an array. See the Geometry Objects topic.

Use a geometry service to do the following:

Buffer, project, and simplify geometry.
Calculate areas and lengths for geometry.
Determine spatial relations and label points.
Determine distances between geometries.
Apply Union, Intersection, and Difference operations between geometries.
Autocomplete, generalize, reshape, offset, trim or extend, and compute convex hulls of geometries.
Convert to or from geographic coordinate strings.

Supported operations

The Geometry Service resource is primarily a processing and algorithmic resource that supports operations related to geometries. The Geometry Service resource has the following operations:


Operation	Details
Areas and Lengths	Calculates areas and perimeter lengths for each polygon specified in the input array.
Auto Complete	Simplifies the process of constructing polygons that are adjacent to other polygons.
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.
Convex Hull	Returns the convex hull of the input geometry.
Cut	Splits the input polyline or polygon where it crosses a cutting polyline.
Densify	Densifies geometries by plotting intermediate points between existing vertices.
Difference	Constructs the set-theoretic difference between an array of geometries and another geometry.
Distance	Calculates the distance between two geometries.
Find Transformations	Gets a list of geographic transformations.
From GeoCoordinateString	Converts a list of strings in a well-known format to x,y coordinates.
Generalize	Returns generalized (Douglas-Peucker) versions of the input geometries.
Intersect	Constructs the set-theoretic intersection between an array of geometries and another geometry.
Label Points	Calculates an interior point for each polygon specified in the input array.
Lengths	Calculates the length of each polyline specified in the input array.
Offset	Constructs the offset of the given input polyline based on an offset distance.
Project	Returns an array of projected geometries.
Relation	Determines the pairs of geometries from the input geometry arrays that participate in the specified spatial relation.
Reshape	Reshapes a polyline or a part of a polygon using a reshaping line.
Simplify	Returns an array of topologically correct geometries.
To GeoCoordinateString	Converts a list of coordinates into strings in a well-known format based on the specified conversion type.
Trim/Extend	Trims or extends each polyline specified in the input array using the user-specified guide polylines.
Union	Constructs the set-theoretic union of the input geometries.
