List of raster functions

The raster functions allow you to define processing operations that can be applied to one or more rasters. These functions are applied to the raster data on the fly as the data is accessed and viewed. This means they can be applied quickly, without the time it would otherwise take to create a processed file on disk. The raster functions are organized in a raster function template, allowing you to create various processed products by chaining together multiple functions.

Global raster functions can be chained together with other functions, but they process data on a specified resolution and extent. Global functions can be identified by the hammer picture Global Function within the function button. They work similarly to geoprocessing tools and can use environment settings that you specify. To learn more, see Global functions.

All local raster functions—more than 100—support multidimensional rasters as inputs. Global functions do not support multidimensional rasters as inputs.

You can change the properties of a raster function on the General tab, including the name, description, output pixel type, and multidimensional rules.
