代码实例

合并 (Combine) 示例 1(Python 窗口)

本例将接收多个不同格式(Grid、IMG 和 TIFF)的输入栅格并将唯一组合值输出为 Grid 栅格。

import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outCombine = Combine(["filter", "zone", "source.img", "dec.tif"])
outCombine.save("C:/sapyexamples/output/outcombine2")
合并 (Combine) 示例 2(独立脚本)

本例将接收多个不同格式(Grid、IMG 和 TIFF)的输入栅格并将唯一组合值输出为 Grid 栅格。

# Name: Combine_Ex_02.py
# Description: Combines multiple rasters such that a unique value is
#              assigned to each unique combination of input values
# 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
inRaster01 = "filter"
inRaster02 = "zone"
inRaster03 = "source.img"
inRaster04 = "dec.tif"

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute Combine
outCombine = Combine([inRaster01,inRaster02,inRaster03,inRaster04])

# Save the output 
outCombine.save("C:/sapyexamples/output/outcombine")
