An overview of the Raster Creation toolset

Available with Spatial Analyst license.

The Raster Creation tools generate new rasters in which the output values are based on a constant or a statistical distribution.

These tools are useful in determining the distribution of a phenomenon. One example of such an analysis would be analyzing whether known bear sightings are randomly distributed within a study site.

Setting the Output cell size and Output extent parameters in the tool will override the values of these settings obtained from the analysis environment.

The following table lists the available tools and provides a brief description of each.

Tools in the Raster Creation toolset

Tool	Description
Create Constant Raster	Creates a raster of a constant value within the extent and cell size of the analysis window.
Create Normal Raster	Creates a raster of random values with a normal (Gaussian) distribution within the extent and cell size of the analysis window.
Create Random Raster	Creates a raster of random floating-point values between 0.0 and 1.0 within the extent and cell size of the analysis window.
