Int (3D Analyst)
Summary
Converts each cell value of a raster to an integer by truncation.

Int_3d (InRas1, OutRas) |
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.
Syntax
| Parameter | Explanation | Data Type |
in_raster_or_constant |
The input raster to be converted to integer. 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 |
out_raster |
The output raster. The cell values are the input values converted to integers by truncation. | Raster Dataset |
Code Sample
This example converts the input values to integer by truncation.
