Geostatistical Layer properties

サマリー

The Describe function returns the following properties for geostatistical layers. The Layer property group is also supported.

For a geostatistical layer, the Describe dataType property returns a value of "GALayer".

プロパティ

プロパティ	説明	データ タイプ
areaOfInterest (読み取り専用)	The extent of the geostatistical layer.	Extent
dataCollection (読み取り専用)	A value table of the datasets used to create the geostatistical layer. It is recommended that you instead use the GeostatisticalDatasets class to determine the source dataset.	ValueTable

Geostatistical layer properties example

The following stand-alone script displays some layer properties from a geostatistical layer:

# Name: Describe_GA_Layer_Example_01.py
# Description: Print the Describe properties of a geostatistical layer.
# Requirements: Geostatistical Analyst Extension

# Import system modules
import arcpy

# Check out Geostatistical Analyst extension
arcpy.CheckOutExtension("GeoStats")

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

# Set local variables
inPointFeatures = "ca_ozone_pts.shp"
zField = "OZONE"
GALayer = "IDW_galayer"

# Execute IDW
arcpy.ga.IDW(inPointFeatures, zField, GALayer)

# Describe the geostatistical layer
desc = arcpy.Describe(GALayer)

# Save extent of geostatistical layer
aoi = desc.areaOfInterest

# Save name of geostatistical layer
name = desc.nameString

# Save data type of geostatistical layer
dt = desc.dataType

# Save data sources and primary input dataset
dc = desc.dataCollection
ds = dc.getValue(0,0)

# Print describe properties
print("Layer name:       " + name)
print("Data type:        " + dt)
print("Input data:       " + ds)
print("Minimum X Extent: " + str(aoi.XMin))
print("Maximum X Extent: " + str(aoi.XMax))
print("Minimum Y Extent: " + str(aoi.YMin))
print("Maximum Y Extent: " + str(aoi.YMax))
