Available with Spatial Analyst license.
Summary
Calculates the square root of the cell values in a raster.
Illustration
Usage
Input values that are less than 0 will be NoData in the output raster.
The output raster from this tool is always floating-point type, regardless of the input value type.
See Analysis environments and Spatial Analyst for additional details on the geoprocessing environments that apply to this tool.
Syntax
SquareRoot (in_raster_or_constant)
| Parameter | Explanation | Data Type |
in_raster_or_constant | The input values to find the square root of. In order to use a number as an input for this parameter, the cell size and extent must first be set in the environment. | Raster Layer | Constant |
Return Value
| Name | Explanation | Data Type |
| out_raster | The output raster. The cell values are the square root of the input cell values. | Raster |
Code Sample
SquareRoot example 1 (Python window)
This example finds the square root of the values in the input Grid raster and gererates the output as an IMG raster.
import arcpy
from arcpy import env
from arcpy.sa import *
env.workspace = "C:/sapyexamples/data"
outSquareRoot = SquareRoot("elevation")
outSquareRoot.save("C:/sapyexamples/output/outsqrt.img")
SquareRoot example 2 (stand-alone script)
This example finds the square root of the values in the input Grid raster.
# Name: SquareRoot_Ex_02.py
# Description: Calculates the square root of cells in a raster
# Requirements: Spatial Analyst Extension
# Import system modules
import arcpy

# Set local variables
inRaster = "elevation"
# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")
# Execute SquareRoot
outSQRT = SquareRoot(inRaster)
# Save the output
outSQRT.save("C:/sapyexamples/output/outsqrt")
