GA Layer To Grid (Geostatistical Analyst)

Geostatistical Analyst のライセンスで利用可能。

サマリー

Exports a Geostatistical layer to a raster.

Learn more about fundamentals of creating a raster from a geostatistical layer

使用法

• Select the number of predictions to make for each cell in the horizontal and vertical directions. The value assigned to each output raster cell will be the average of all predictions within that cell.

• The GA Layer To Rasters tool can also be used to export a geostatistical layer to one or multiple rasters.

• The name you give to the output raster determines the format in which it is created. When not saving to a geodatabase, specify an extension of .tif for a TIFF raster format, .img for ERDAS IMAGINE format, or no extension for an Esri Grid raster format.

Output cell size (オプション)	The cell size at which the output raster will be created. This value can be explicitly set in the Environments by the Cell Size parameter.

コードのサンプル

GALayerToGrid example 1 (Python window)

Convert a geostatistical layer into a raster.

import arcpy
from arcpy import env
arcpy.GALayerToGrid_ga("C:/gapyexamples/data/kriging.lyr", 
                       "C:/gapyexamples/output/krig_grid", "2000", "1", "1")

GALayerToGrid example 2 (stand-alone script)

Convert a geostatistical layer into a raster.

# Name: GALayerToGrid_Example_02.py
# Description: Exports a geostatistical layer to grid.
# Requirements: Geostatistical Analyst Extension

# Import system modules
import arcpy

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

# Set local variables
inLayer = "C:/gapyexamples/data/kriging.lyr"
outGrid = "C:/gapyexamples/output/krig_grid"
cellSize = 2000
cellptsHor = 1
cellptsVer = 1

# Execute GALayerToGrid
arcpy.GALayerToGrid_ga(inLayer, outGrid, cellSize, cellptsHor, cellptsVer)
