Smooth Raster
The Smooth Raster tool is designed to smooth digital elevation models (DEMs) by reducing surface roughness while preserving significant topographic features such as breaks in slope. The tool has the following options:
Input Parameters
- Input raster – Select the raster that will be smoothed.
- Filter size – This determines how many points will be included in the smoothed raster
- Number of interations – This specifies how many passes should be made with the smoothing algorithm.
- Maximum elevation change – This value specifies the maximum allowable elevation change per iteration for each cell.
- Filter ratio (0.0 – 1.0) – The new cell elevation is computed using the original elevation (at the beginning of the iteration not the whole process) and the "blurred" elevation. The filter ratio defines how far the elevation is changed between the original elevation and the "blurred" elevation. A filter ratio of 1.0 would replace the existing elevation with the "blurred" elevation. A filter ratio of 0.0 would be pointless as it wouldn't change the elevations. A filter ratio of 0.5 would give a new elevation that is the average of the original elevation and the blurred elevation.
- Define maximum change from original raster or per iteration – Select an option for defining maximum change:
- "Maximum change defined from original raster"
- "Maximum change defined for each iteration"
Output Paramters
- Output raster – Enter the name for the new smoothed raster.
