I have problem in smoothing the slope derived from digital elevation model. I want to do filter for the slope 20 degree slope in 3X3. But I am not able to put these kernel size condition in filter tools in ArcGIS Desktop 9.3.
use the Focal Statistics Tool from the Spatial Analyst Extension. Use as Neighborhood Type Weight. Here in a text file you can define any size and values for your filter kernel. Define your 3 different filters, apply them on your slope raster and combine the resulting three smoothed rasters using the raster calculator with the con-funcion.
