Feature Preserving Smoothing
This tool is designed to smooth digital elevation models (DEMs) by reducing surface roughness while preserving significant topographic features such as breaks in slope. It works by calculating and smoothing surface normal vectors and then updating the elevations based on this smoothed data.
Input parameters
- Input raster DEM file – Select the file that will be modified.
- Size of the filter kernel – Defines the dimensions of the 3x3 neighborhood used to calculate surface normal vectors and smooth them.
- Maximum difference in normal vectors, in degrees – Sets the threshold for the angular difference between surface normal vectors.
- Number of iterations – Specifies how many times the smoothing algorithm will be applied to the DEM.
- Maximum allowable absolute elevation change (optional) – Sets a limit on the maximum permitted change in elevation between the original and smoothed DEM values.
- Optional multiplier for when the vertical and horizontal units are not the same – Adjusts the scale of vertical elevation changes to account for differences in units between vertical and horizontal measurements.
Output parameters
- Output raster file – Enter the name for the new generated model.
