Unchanged, original terrain without erosion applied.
With morphological erosion in Dilate mode, using Circle shape setting.
With morphological erosion in Erode mode, using Circle shape.
tfErosion Morphological, Properties tab menu settings.
This sets the size of the structures created in the morphological process.
Larger values will yield a more pronounced effect, and take longer to compute.
The options are Dilate or Erode.
Dilate will typically present a flatter, plateau at the highest parts, while Erode does just that, giving a more natural look, with less ‘sharp’ angles on edges.
Enable this to use a Gaussian kernel, adding a smoothing effect.
If Gaussian is disabled, select one of several available shapes for the structuring element matrix, used in the morphological process here.
The options are: Box, Circle, Along U, Along V and Cross; each yields a distinctive look.
