Cut

Description

The cut operation is performed on a geometry service resource. This operation splits the target polyline or polygon where it's crossed by the cutter polyline.

At 10.1 and later, this operation calls simplify on the input cutter and target geometries.

You can provide arguments to the cut operation as query parameters defined in the following parameters:

Request parameters

Parameter

Details

f

Description:  (Optional) The response format. The default response format is html.
Values:   html | json

cutter

Description: The polyline that will be used to divide the target into pieces where it crosses the target.The spatial reference of the polylines is specified by sr. The structure of the polyline is the same as the structure of the JSON polyline objects returned by the ArcGIS REST API.

JSON structures:

Syntax:

<polyline1>

Example:

{
  "paths" : [
   [[-117,34],[-116,34],[-117,33]],
   [[-115,44],[-114,43],[-115,43]]
  ]
 }

target

Description: The array of polylines/polygons to be cut. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API. The spatial reference of the target geometry array is specified by sr.

JSON structures:

Syntax:

{"geometryType" : "<esriGeometryPolyline | esriGeometryPolygon>""geometries" : [ <geometry1>, <geometry2> ]}

The target property is a geometry of the type defined by geometryType.

Example:

{
  "geometryType" : "esriGeometryPolyline",
  "geometries" : 
  [
    {
      "paths" : 
      [
        [[-117,34],[-116,34],[-117,33]],
        [[-115,44],[-114,43],[-115,43]]
      ]
    },
    {
      "paths" : 
      [
        [[32.49,17.83],[31.96,17.59],[30.87,17.01],[30.11,16.86]]
      ]
    }
  ]
}

sr

Description: The well-known ID of the spatial reference or a spatial reference JSON object for the input geometry. For a list of valid WKID values, see Projected coordinate systems and Geographic coordinate systems.

Example usage

Cut a polyline geometry.

JSON response syntax

The geometry server's cut method returns a cutIndexes array along with an array of cut geometries. The cutIndexes array can be used to determine which of the input geometries were cut to get the resultant geometries.

{
 "geometryType" : "<esriGeometryPolyline | esriGeometryPolygon>", 
 "geometries" : [ <geometry1>, <geometry2>, ..., <geometryN> ], 
 "cutIndexes:" : [ integer1, integer2 ]
}
