FeatureSet (arcpy)

Summary

FeatureSet objects are a lightweight representation of a feature class. They are a special data element that contains not only schema, but also the data. The FeatureSet object is also how feature data is sent and received from the server.

Syntax

FeatureSet ({table})

Parameter	Explanation	Data Type
table	Feature data to be loaded into the FeatureSet object.	String

Properties

Property	Explanation	Data Type
JSON (Read Only)	Returns a JSON representation of the geometry as a string. Tip: The returned string can be converted to a dictionary using Python's json.loads function.	String

Method Overview

Method	Explanation
load (table_path)	Import from a table.
save (table_path)	Export to a table.

Methods

load (table_path)

Parameter	Explanation	Data Type
table_path	The table to be imported.	String

save (table_path)

Parameter	Explanation	Data Type
table_path	The output table to be created.	String

Code Sample

FeatureSet example

Load data into FeatureSet and insert into feature class.

import arcpy

arcpy.env.overwriteOutput = True

arcpy.ImportToolbox("http://flame7/arcgis/services;BufferByVal",
                    "servertools")
