Summary

Converts each cell value of a raster to an integer by truncation.

Usage

  • The input values can be either positive or negative.

  • If rounding is preferred to truncating, add a 0.5 input raster prior to performing the operation.

  • The maximum supported range of integer raster values is -2,147,483,648 (minimum size determined by -231) to 2,147,483,647 (maximum size determined by 231 – 1). If Int is used on a floating-point raster which has cells with values outside this range, those cells will be NoData in the output raster.

  • Storing categorical (discrete) data as an integer raster will use significantly less disk space than the same information stored as a floating-point raster. Whenever possible, it is recommended to convert floating-point rasters to integer with this tool.

  • 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.

  • If the input is multidimensional raster data, all slices from all variables will be processed. The output will be a multidimensional raster in CRF format.

Parameters

LabelExplanationData Type
Input raster or constant value

The input raster to be converted to integer.

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
Output raster

The output raster.

The cell values are the input values converted to integers by truncation.

Raster Dataset

arcpy.ddd.Int(in_raster_or_constant, out_raster)
NameExplanationData Type
in_raster_or_constant

The input raster to be converted to integer.

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
out_raster

The output raster.

The cell values are the input values converted to integers by truncation.

Code sample

Int example 1 (Python window)

This example converts the input values to integer by truncation.

import arcpy
from arcpy import env
env.workspace = "C:/data"
arcpy.Int_3d("gwhead", "C:/output/outint")
Int example 2 (stand-alone script)

This example converts the input values to integer by truncation.

# Name: Int_3d_Ex_02.py
# Description: Converts each cell value of a raster to an integer by truncation
# Requirements: 3D Analyst Extension

# Import system modules
import arcpy
from arcpy import env

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

# Set local variables
inRaster = "gwhead"

# Execute Int
arcpy.ddd.Int(inRaster, "C:/output/outint")
