I am using ArcMap 10.6.1 and I need to expand a large raster with tens of thousands of zones by 1 cell using either the expand tool or a map algebra expression. The tool asks to specify each zone to be expanded but I have too many zones for this approach.
How can I write a map algebra expression in raster calculator to expand all zones in the input raster without entering each zone value separately i.e. is there a way to write it so it expands zones from one number through to another?
So for a range of raster values from the input raster.
