FeatureSet (arcpy)

Zusammenfassung

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})
ParameterErläuterungDatentyp
table

Feature data to be loaded into the FeatureSet object.

String

Eigenschaften

EigenschaftErläuterungDatentyp
JSON
(Schreibgeschützt)

TippTipp:

The returned string can be converted to a dictionary by Python's eval function.

FeatureSet example

Load data into FeatureSet and insert into feature class.

import arcpy
from arcpy import env

env.overwriteOutput = True

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

# List of coordinates
