geometries

Specifies the array of geometries to be generalized. The spatial reference of the geometries is specified by sr. The structure of each geometry in the array is the same as the structure of the JSON geometry objects returned by ArcGIS REST API.

The geometries property is an array of input geometries. All geometries in this array should be of the type defined by the geometryType property.

    }
  ]
}

sr

Specifies the well-known ID (WKID) or a spatial reference JSON object for the input geometries. For a list of valid WKID values, see Using spatial references.

maxDeviation

Sets the maximum allowable offset, which determines the degree of simplification. This value limits the distance the output geometry can differ from the input geometry.

deviationUnit

(Optional)

Specifies a unit for maximum deviation. If a unit is not specified, the units are derived from sr. For a list of valid units, see esriSRUnitType Constants and esriSRUnit2Type Constants.

f

The response format. The default response format is html.

Values: html | json | pjson
