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.
If the input is a multiband raster, the output will be a multiband raster. The tool will perform the operation on each band in the input.
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. 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
This example finds the square root of the values in the input Grid raster and generates 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")
This example finds the square root of the values in the input Grid raster.
