Code sample

GetCellValue example 1 (Python window)

This is a Python sample for the GetCellValue tool.

import arcpy
result = arcpy.management.GetCellValue("C:/data/rgb.img", "480785 3807335", "2;3")
cellvalue = int(result.getOutput(0))
print(cellvalue)

GetCellValue example 2 (stand-alone script)

This is a Python script sample for the GetCellValue tool.

#====================================
# Get Cell Value
   
import arcpy
arcpy.env.workspace = "C:/Workspace"

# Get the Band_2 and Band_3 cell value of certain point in a RGB image
result = arcpy.management.GetCellValue("rgb.img", "480785 3807335", "2;3")
cellvalue = int(result.getOutput(0))

# View the result in execution log
print(cellvalue)
