## Zusammenfassung

Defines a variable search radius by specifing a maximum distance and the number of points for analysis. If the number of points cannot be satisfied within that maximum distance, a smaller number of points will be used.

## Diskussion

Tools that use radius objects: Kriging and IDW.

## Syntax

` RadiusVariable ({numberOfPoints}, {maxDistance})`
 Parameter Erläuterung Datentyp numberOfPoints The numberOfPoints is an integer value specifying the number of nearest input sample points to be used to perform the interpolation. (Der Standardwert ist 12) Long maxDistance The maxDistance specifies the distance, in map units, by which to limit the search for the nearest input sample points. The default value is the length of the extent's diagonal. If the number of points cannot be satisfied within that distance, a smaller number of points will be used. Double

## Codebeispiel

Demonstrates how to create a RadiusVariable class and use it in the Kriging tool within the Python window.

``````import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"

Calculates a surface with the Idw interpolation tool using the RadiusVariable class.

``````# Name: RadiusVariable_Ex_02.py
# Description: Uses the RadiusVariable object to execute IDW tool.
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Set local variables
inFeature = "ca_ozone_pts.shp"

numberOfPoints = 5
maxDistance = 200000

# Execute IDW

# Save the output
