Fill Holes and Slivers in Imagery (Single Value)

Here is a graphic Spatial Model (PaulBeaty_HoleFiller.gmd) I created when I was at Georgia Tech. It fills DEM and other raster data (including imagery) holes and slivers with data calculated values from surrounding pixel values. These 1, 2 and sometimes 3 pixel wide artifacts are common to users who have reprojected butt-matched raster data. This model finds the "to-be-replaced" value and determines whether a 3 x 3 or 5 x 5 focal mean should be applied. The model ignores the replacement value when calculating the focal mean.

Copy and paste the text below into a text editor and save as ANSI text file without the text editor's formatting. Save as PaulBeaty_HoleFiller.gmd and open in Model Maker.
